6 Cell Plug Tray Inserts - Multi-Color Pack - Bootstrap Farmer
Need a flexible seed starting solution that lets you grow multiple varieties without committing entire trays to each crop? Bootstrap Farmer's 6 Cell Plug Tray Inserts are perfect for gardeners who want to start small quantities of different varieties while maximizing their growing space. Made in the USA from heavy-duty, food-safe plastic with innovative air-pruning technology, these inserts are built to last for years.
Why These Inserts Stand Out
Air-pruning technology for healthier roots: These aren't ordinary cell inserts. Each tray features vertical air pruning slits (0.11" wide x 1¼" tall) on all four sides. When roots reach these openings, they're naturally "air-pruned," which prevents root circling and promotes a healthier, more fibrous root system. Air-pruned seedlings develop more vigorous growth and transplant with less shock.
Extra-large drainage for easy removal: The ⅝" drainage hole on the bottom of each cell makes seedling removal incredibly easy. No more struggling to dig out plants or damaging tender roots—just push from below and your seedlings pop right out.
Perfect for variety testing: Twelve 6-cell inserts fit perfectly in a Bootstrap Farmer 10x20 tray. This modular design lets you start 12 different varieties in the same footprint, removing each insert as plants become ready without disturbing the others sharing the bottom-watering tray.
Multi-color for easy tracking: The variety pack includes multiple colors, making it simple to color-code different varieties, planting dates, or growing experiments. No more mixing up your tomatoes and peppers—visual identification at a glance.
Heavy-duty construction: These aren't throwaway inserts. Made from FDA Prime Grade Extra Strength Polypropylene (#5, BPA-free) plastic that's built for years of repeated use. We've grown countless varieties on Bootstrap Farmer trays both indoors under grow lights and outdoors with excellent results.
Made in the USA: Quality construction you can trust, manufactured domestically from food-safe materials.

The 1½" x 1½" cell size provides ample room for seedlings to develop strong root systems without becoming root-bound too quickly.
How Air Pruning Works
Traditional cell trays cause roots to circle when they hit the walls, creating weak, tangled root systems. The vertical slits on these inserts expose roots to air as they reach the edges. This "air-prunes" the tips, triggering the plant to develop more lateral roots instead of circling. The result? Healthier, more vigorous seedlings with fibrous root systems that transplant beautifully with minimal shock.
Compatible Growing System
Bottom-watering setup: Place 12 inserts in a Bootstrap Farmer 10x20 Deep Tray for efficient bottom-watering. Fill the bottom tray with water, and all 72 cells (12 inserts x 6 cells) water simultaneously from below.
Modular flexibility: Remove individual 6-cell inserts as crops become ready for transplant without disturbing neighboring varieties. This is perfect for crops with different growth rates or when succession planting.
Stackable design: The tapered cell design allows empty inserts to stack for compact storage.
Pro Tips
Prevent soil spillage: Some soil may fall through the large drainage hole when first filling cells with dry mix. Use pre-moistened potting soil to minimize spillage—the moisture helps the soil hold together.
Easy transplanting: Use a widger dibber or similar tool to push seedlings up from the bottom drainage hole for effortless removal.
Color coding: Assign colors to crop types, planting dates, or growing experiments for easy visual tracking.
Care & Maintenance
Cleaning: Hand-wash with warm, soapy water between uses. Can also be cleaned in dishwasher (without heated dry cycle).
Storage: Store out of direct sunlight when not in use to maximize lifespan. Stack empty inserts using the tapered design for compact storage.
Longevity: With proper care, these inserts are built to last for years of continued use.

Guns Germs & Steel Book Review
Format: Hardcover
Guns, Germs, And Steel is an influential treatise of competitive plausibility regarding the challenging question why population groups on different continents experienced widely divergent paths of development. Contrary to the voluminous objections cited in the many of the revisionist historians and anthropologists, the famous biologist Jared Diamond tackles the most important question of global history in one compelling volume: "Why did Europeans come to dominate the New World?" This question has been answered by others before and Diamond's idea that Europe's geography is the cause geographical determinism has also been proposed before. Any student of history or anthropology can drag up a case or two of this thesis. Baron Montaigne, for example, suggested that Europe's predominance curtailed from its superior government, which could be derived directly from the coolness of its climate. However as an enthusiastic proponent of environmental determinism, Jared Diamond presents a set of premises consistent with evidence provided from a wide range of disciplines, but he does not attempt to answer the question of genetic diversity, including segregated intelligence among racial groups as many reviewers have inferred. If anything, implicitly, the author appears to support promulgations of differentiated intelligences; he sets out to demonstrate intelligence was not the root cause to Eurasian dominance.
The deep significance of this book is that Diamond's thesis is not simply idle conjecture. He proves that the Eurasian land mass had by far the best biological resources with which to develop agricultural societies, and was thus more able to form large, coherent, and powerful social entities. In order to back this idea, Diamond introduces a set of well-researched data on what kinds of plants and animals are necessary to support a farming society. He investigates the biological resources available to potential farmers in all parts of the world. The people of Eurasia had access to a suite of plants and animals that provided for their needs. Potential farmers in other parts of the world did not have such access and so, their fertile soil went uncultivated. Beginning 13,000 years ago, the author illuminated the circumstances that may have smoothed growth for some groups and repressed the same for others. Diamond accepts the out of Africa theory for the dispersion of Homo sapiens to the other continents as well as the importance of location that they went. For Diamond, food production is the definitive cause of capricious rates of development for different peoples. He demonstrates how the abundance of wild plants subject to domestication and availability of large mammals served as immediate factors to transition from hunter/gatherer bands and tribes to sedentary agriculturally based chiefdoms and states. In this context, Eurasia was home to important number of crops and animals that readily and successfully domesticated. This domestication resulted in mass food production, which the author claims is the "ultimate" cause of Western dominance. Food production in turn, led to a number of adjoining causes related to the rise of the West:- farms and animal herds led to stationary populations and excess food to support a specialized class of bureaucrats and soldiers and it also increased population density.
After establishing this strong foundation, Diamond falls into reiterating ideas about the creation of large-scale societies. These ideas, while clichéd, are still enthralling and Diamond presents them in a very clear and well-written way. His other major original contribution comes when he discusses the diseases that helped the Old World conquer the New World. Building on his earlier chapters dealing with Old-World domesticated animals, he shows that these very animals were the sources of the major plagues such as smallpox which virtually annihilated New World populations. The fact that Old World people had immunities to these diseases was a direct result of their agricultural head-start. Finally, Diamond concludes, the unique East-West axis of Eurasia and the absence of any impenetrable geographic barriers fostered the spread of new crops, technologies which gave rise to many competing communities, whose competition further increased the western lead over the rest of the world.
These technical details, while complete, are presented in a very easy to fathomable way and Diamond's writing style is fun and engaging. Diamond's arguments are persuasive on the surface, and even the prevalent skeptic will have reason for pause after reading his book.
However, I have some concerns with respect to the credibility of this book. I felt that I had to second guess most of his evidence, because it was equivocal, lacking or incorrect. Firstly, Diamond uses the term "Eurasian" to describe cultures and societies. However, the term is essentially used to describe a geographical landmass or tectonic plates. All the way through the book, he uses the term "Eurasian" when it supports his hypothesis and replaces the term with European or western Eurasian to support another part of his thesis. He does not separate Europe and Asia to explain societies and cultures even though Europe and Asia contain different religions, cultures and languages. But then again, he separates "North Africa" from "Sub-Saharan Africa" even though they are part of the same continental landmass and have more commonalties. On page 161, Diamond attempts to explain his reasoning behind using the broad and vague term "Eurasian" when he states that: "my use of the term "Eurasia" includes in several cases North Africa, which biogeographically and in many aspects of human culture is more closely related to Eurasia than to sub-Saharan Africa". I believe Diamond confuses contemporary North African culture with the cultures that inhabited Northern Africa from 10,000 BC to 8th century AD. For example, from pre-dynastic to the mid-late stages of the Ancient Egyptian civilization, the ancient Egyptians had contact and traded with cultures in Ethiopia (sub-Saharan Africa). The Ancient Egyptian and Amharic language (Ethiopia) belong to the same language group which is Afro-Asiatic, and also belong to the same sub language group, which is Semitic. Diamond makes vague generalities in supporting his thesis and fails to engage significant evidence that challenges his thesis.
In addition, when studying the development of different cultures and the spread of food production and technology, he modifies the definition of different terms to fit his hypothesis. Any hypothesis can be supported if you continuously alter the variables you are challenging. I found this to be the most distracting facet of this book. He does this with the terms "North African" and "Sub-Saharan African" which are terms that carried little meaning between 13,000 BC until the 7th century, but are used to separate the significant accomplishments of Ancient Egyptians (Africans) with other Africans. On page 92, he states that: "the availability of domestic plants and animals ultimately explains why empires, literacy, and steel weapons developed earliest in Eurasia and later, or not at all, on other continents." That statement is false, since written records of the Ancient Egyptian (African) language have been dated from about 3200 BC, making it the oldest and longest documented language. The Sumerian language, as Diamond claims is the oldest language, developed around 3000 BC. Additionally, a recent archaeological discovery has suggested that some Gerzean pottery with early hieroglyphics located in Egypt could have originated since 4000 BC.
Ancient Egyptians were also the first to develop mathematic concepts such as the Decimal system and science such as astronomy and medicine during that time period and significantly influenced Greek science and mathematics. Diamond does not mention any of this and I believe that he leaves out noteworthy attainments by non-Europeans to support his thesis. Throughout the book, Diamond also poses the following question in the background: "Why were Eurasians, rather than Native Americans or sub-Saharan Africans, the ones to invent firearms, oceangoing ships, and steel equipment?" Nevertheless, Diamond does not engage in the most basic question relating to the motivations of these cultures: Did Native Americans or Sub-Saharan Africans have a need for firearms/oceangoing ships? More to the point, did the Native Americans, sub-Saharan Africans, and other so-called non-Eurasians, want firearms or oceangoing ships? The answer would have forced Diamond to research the cultures and religions of Native Americans and Sub-Saharan Africans in more detail, rather than explaining it with geography and/or food production.
Also, he does not include the significant accomplishments of Ancient Egypt, including papyrus, an early form of paper that originated in Africa not Europe or Asia. On page 190, Diamond states that: "Continental differences in axis orientation affected the diffusion not only of food production but also of other technologies and inventions." It is known that Ancient Egyptian technology including scientific or medical discoveries traveled along the north or south axis towards the Middle-east and eventually to ancient Greece. Diamond doesn't mention any of this, which further questions the credibility of the book. Another problem with Diamond's style is that he seems to negate the influences of Non-Europeans, specifically Africa and China, to the current Western hegemony such as gunpowder from China, natural resources from Africa by either not mentioning them at all or under-emphasizing their importance. It is quite likely that without the influences from non-European civilizations that current Western hegemony would not exist today. He also makes downright false statements such as in page 247 when he states that: "Delivered in grenades, rockets, and torpedoes, those incendiaries played a key role in Islam's eventual defeat of the Crusaders." According to historical records, there is no evidence to suggest that grenades, rockets and torpedoes were used during the Crusades.
I agree that the domestication of plants and animals could predispose agriculturalists to further development. However, geography and domestication of animals and plants alone is inadequate to support his thesis without explaining the role of the people and societies occupying the geography. Geography might be a factor to explain how Western Civilization became the dominant civilization in the world today. Though, European civilization did not arise in a vacuum. Regardless of the plausible geographic advantage of Europe and Asia, factors such as political intentions, morals, ethics, religion and culture all served to explain why some civilizations were determined to expand and build empires through conquest, while others did not. Diamond claims that his theories offer an alternative explanation to traditional racist dogma. Conversely, I believe his theories do just the opposite. By stating that Europeans developed into the dominant civilization by "chance" or "luck" with respect to geography strengthens racist theories that European civilization was "destined" to become the most powerful.
Moreover, Diamond dismisses politics, religion, culture, individuals, and timing. For example, consider Cortez's victory over the Aztecs. Cortez's victory was not assured. Many elements had to be aligned for a few hundred Spaniards to overcome a mighty empire. The odds were really in Montezuma's favor. Even with horses, armor, and guns, the Aztecs were easily a match for Cortez. The Spanish armor was superfluous. According to Keegan, they even shed their heavy armor in favor of the native quilt vests. The firearms at that time were not quick to reload, so sheer numbers could have overwhelmed the Spanish. The Aztecs lost because of politics, religion, and individuals. The brutal politics and religion of the Aztecs made their subjects hate them. The Spanish were immediately supported with armies and food by the smaller nations like the Totonacs that hated the Aztecs for their cruelty. The insatiable appetite of the Aztec gods for human sacrifices insured that Cortez found ready allies. If either Montezuma or Cortez had been composed of slightly different temperaments the war could easily have gone the other way. Had Montezuma been more decisive, he could have had Cortez killed at the coast. Had Cortez not been so incredibly determined to take the country, he could have just returned to Spain with a load of the early gold presents sent to him.
History is determined by far more than geography, plants, and animals. Culture, religion, individuals, politics, and timing all play important roles. My criticisms have nothing to do with "political correctness", but rather I take issue with Diamond's style of revisionist history that does not emphasize the influence and significance of non-European civilizations towards current Western civilization. While reading the book, I was frequently second guessing the facts of Jared Diamond because they were either inexact or vague.
In closing, as an introduction to anthropology and a cogent depiction of one school of thought on the rise of the West this book is marvelous. However, it needs to be approached with an open-mind as it has some of its faults. Reflect on the thesis and the supporting evidence, and then draw your own conclusions. Love it or hate it, you owe it to yourself to read this book. As for me, this book is one of the best revisionist histories on the Ancient Civilizations but as the case with revisionist history, it has its share of one sided and extreme arguments. It is a good book but not great. Still, it is very simple to read and very easy to cognize which I think deserves the Pulitzer Prize it won.

Excellent. Not just pictures but also retrospective commentary, better in that than some other game art books out there which are just images without context. And of course these games are incredibly artful and the images themselves are worth looking at. Beautiful book inside and out

This was my first book purchase, top notch quality and the feeling every page as you touch and turn it is satisfying, delivery was also earlier than anticipated. Some of the concept art in the book is available online if you know where to look, but there are some never seen before art in there too, plus the tidbits shared by the developers is nice and gives cool behind the scenes information, overall a great deal for any Deus Ex fan.

Yes, I Absolutely Asked For This.
Format: Hardcover
The Art of the Deus Ex Universe is a gorgeous artbook that encompasses Eidos Montreal’s past two Deus Ex games, Deus Ex Human Revolution and Deus Ex Mankind Divided. It starts with the foreword by the creator of Deus Ex Warren Spector who talks about the game he created being a classic and giving his approval of the latest games saying they keep the spirit of the original alive. From there you get five chapters of great art and behind the scenes commentary by the Art Director Jonathan Jacques-Belletete and Martin Dubeau. The five chapters are in order characters, weapons and tech, locations, the breach, and in-game adverts. The last two are short and brief compared to the first three chapters. You see the concepts on how they nailed the uniques aesthetic designs of Human Revolution and Mankind Divided. The “cyber-renaissance” look, as the art director calls it. The art style of these games give off a Cyberpunk dystopian look; that does not seem too far fetched to believe might happen. The Art of the Deus Ex Universe is a fantastic art book you get two games in one art book. You get good looking art concepts and fun making of Deus Ex facts. Such as the colors pink, violet and purple do not exist in the world of Deus Ex giving the visual metaphor of Eliza Cassan being an AI as she the only person who wears purple in the entire two games. There are many fun facts like that all over the art book as well as the beautiful artwork. A must for Deus Ex afficandos!

Even if you're not big into books, you totally asked for this one!
Format: Hardcover
Eidos Montreal's work in the Deus Ex series is a standout in the science fiction genre in terms of art direction. The art design in their games is a unique mixture of classical elegance and technological achievement; it is both gorgeous in some ways and somber in others. This book is an excellent showcase of art, and it also provides meaningful developer commentary on the rationale behind many designs seen in the games. Overall, this artbook is excellent, and a must-have for fans of the series who enjoyed the art design of the games.
