Grodan AO 50/40 6/15 Cube, 2x2" sheet of 50 cells

I have very few compliants about this product. Overall, I like it quite a bit, but not enough for 5 stars.Pros:-Nice big blocks (for my seedling bin, I found I had to cut these into quarters, which makes them last longer-excellent absorbency-takes on any pH you soak them in (takes a few hours or soaking, but it maintains pH for rose cuttings very well)-great for most seedsCons:-not great for ALL seeds (wet feet is the culprit for 70% of plant failures, and it is easy to have wet feet with these)-Somewhat hard to maintain uniformity in water retention when cut into quarters for my seedling bin. Somewhat inconsistent density could be part of it.Overall, I'd like to see the manufacturer produce a list of common herbs, flowers, and indoor/outdoor plants and give recommendations regarding water amounts for seedlings. Learning myself has been rough.

not packaged the same, in a plain plastic bag, so it could be anything, ph is ok, there are some discolored parts of the rockwool, only time will tell if it affects anything. Also rockwool for those who havent used it holds ALOT of water, water too much for some plants that dont like wet feet. (Tomatoes, peppers, hops, cannibis.) but with propper drainage that problem too can be overcome very easily happy growing.

Ok if you know what your doing cubes are not separated you have to cut them apart or rip them

:)

Just make sure to soak cubes and check PH before using-- otherwise Great product!!

Very happy with the speed of delivery, the quality of the product and would recommend it to anyone needing to start and germinate seeds for their hydroponic system. Also good for starting seedlings as well. Excellent product.

I do like this product. It is easy to use and I had NO problems with it. I DO recommend it and I WILL purchase again as needed.

Fake!!! Not what they are advertising
