How To Hang Your Fluorescent T5 Grow Light

Specifically for seed starting and plant cloning, you will want to keep your T5 light about 6" - 12" above your seedlings to help prevent excessive stretching. This also ensures you are giving your plants plenty of light energy. Once they grow past the seedling stage, the light can be raised to around 12" - 24" above the top of the plant canopy which increases the light coverage.

Always test the canopy level to gauge leaf surface temperature, since canopy temperature and room ambient temperature might vary. If your hand gets too hot at the plant canopy level, then the light is most likely too close to the plants and should be raised up. Read our complete guide on how to hang grow lights for more information.

Why use Fluorescent Grow Lights?

Fluorescent lights have been a staple in grow rooms around the world for as long as grow lights have been around, and for good reason. Fluorescent technology is great for growers that want a higher intensity light compared to CFLs, but can’t afford the height & investment requirement that other lights require. Fluorescent Grow Lights are great for the vegging and Cloning and Propagation , plus they can be placed much closer to the canopy of your plants.

Color temperature has a strong influence over plants and different temperatures will affect plants in different ways. A blue or bright white found in the temperature range of 5000K is recommended for plants in the vegetative stage as it keeps them short and bushy.

Color: Blue, Size: Queen Size Set of 2, Color: Blue, Size: Queen Size Set of 2
pillow whore here 🤭 and I very rarely find anything worth writing a 5 star review for but let me just save you the time of searching anymore for the PERFECT pillow!!! BUY THEM! 😍 I promise you will NOT be disappointed!! I have spend thousands on pillows over the years, trying to find the perfect pillows... As someone who suffers from debilitating chronic pain and who has had multiple neck and back surgeries I'm very particular about pillows & have such a hard time finding one's that are comfortable, not too hard, not too soft but also offer great support. I FINALLY found them 🥹 and my hubby is Italian and stays hot but gets even hotter when he sleeps so finding an authentic cooling pillow has seemed impossible UNTIL now!! Just wow!! Now Im adding more to my cart while they are still 70% off 🥳🤩

Loved the pillows
Color: Blue, Size: Queen Size Set of 2
I don’t get paid for reviews so if you want a real one here ya go …. These pillows are great in my opinion. They came vacuum sealed and popped right up “ big and fluffy” immediately, as in big enough I wasn’t sure they would fit in my pillow cases. I used them last night and even though they are full, big and fluffy they still smashed down to a proper size when I laid my head down. First night in a long time I did wake up with a headache. I was extremely happy with these pillows. Now cooling ….I didn’t really find a difference from a reg pillow but, that again just could be me. Hope this helps

Heavenly Sleep Upgrade – DIORIS Pillows Are a Dream Come True!
I’ve finally found the perfect pillows! The DIORIS Queen Pillows Set of 2 has completely transformed my sleep experience. From the moment I laid my head down, I felt like I was at a luxury hotel — but right in my own bedroom! These pillows strike the ideal balance between softness and support. The premium down alternative filling cradles the head and neck gently, yet offers just the right amount of firmness. Whether I sleep on my side, back, or stomach, these pillows adapt perfectly and keep me comfortable all night long. The slow-rebound, breathable fiberfill is a game changer. It stays cool, supports proper posture, and even helps reduce neck pain — something I’ve struggled with for years. I wake up feeling refreshed and ache-free, which is priceless.
