How do I use PRO-MIX® HP®?

To use PRO-MIX® HP®, open the package, remove some PRO-MIX® product and place into a large tub or container. Lightly break up any clumps so that the PRO-MIX® is light and airy. Most growers prefer to add a small amount of water prior to filling containers. If you add water, add enough so that the PRO-MIX® product is slightly moist to the touch. Do not saturate. Fill flats, containers and/or pots, without compacting the PRO-MIX® in the container. Plant your seedlings, young plants, etc., then water in containers.

Shipped quickly and as described
It was what I expected as functionality, lightweight and easy to move about. I plan to use it in my enclosed patio to obscure weight bench and wts. My only complaint is that the bamboo cover on one edge is not secure. But I will probably use a magic marker to cover the natural back that is showing. I don’t have time to return it as my event is coming soon.

Good product, needs double hinges for versatility.
Size: 6 Panel, Color: Brown
Blocks out all the light, looks good, good color. Only con is that it is not double hinged so it is hard to position the extra panels because I bout 6 panels instead of the 4 I usually get. Good deal, very decent price with the free delivery. Very clean packaging, came in great shape, no smell or odor from the factory.

Very Pleased with Room Divider
Size: 4 Panel, Color: Brown
This room divider is even better than I expected. It's sturdy but is lightweight enough that I could get the box up a flight of stairs with no problem whatsoever. It folds and unfolds easily and is very easy to move. And there's no assembly required! It really is woven and is quite attractive. The main reason I chose this item was price (although I did like the way it looked) and I got more for my money than I thought I would.

Works well
Size: 4 Panel, Color: Coal Black
i bought this for 3 reasons. 1. Privacy when changing so I don't have to lock dog out of room. 2. In case MIL comes over and wants to snoop. She won't be able to see my bedroom. 3. A nice backdrop to use when taking photos of the clothing I make. This is perfect for me. My only "complaint" is that it is not the most sturdy thing. I have to finagle it in a way that keeps it from falling over. But for the price, it can't be beat!

Cheap and unstable
Size: 4 Panel, Color: Black, Size: 4 Panel, Color: Black
Although this has nothing to do with the product, it arrived a day later than previously stated. Making me have to create a makeshift room divider the day it was actually needed. When the product arrived it arrived in a box that showed no evidence of damage. Once opened, divider was found inside a plastic cover. Great protector for dust or scratching. The divider was fully assembled so there was nothing for me to do but remove it from packaging and use it where needed. After further inspection the divider was not only cheap and flimsy looking it was absolutely unstable. It would wobble and appears to have been assembled in a rush making some panels crooked. I noted significant damage to the bottom portion of some of the panels both front and back. It does not feel like an item worth the price. The color is as advertised and the product had no smell. The sizing was accurate.
