Great for seed starting!I like this better then anything I ever used for starting seeds.Had to cut my block with a saw but i didn't mind i was cutting a 1 x 3 inch cut that filled 12 1x1 inch trays. It really expanded and wasn't messy. I did cut the block in a box because that was messy but again i feel it's worth it because this stuff works.

Amazing product! I planted tomato seeds on 2/25. It's 3/3 and I'm already seeing them sprout up. I'll never buy plants from the nursery again if this works out.

This worked just as described. It expanded into a lot of soil. I see a lot of organic matter. I am hoping there won't be any weeds. I will follow up after my seedlings sprout. If it works I would definitely buy more. Great value.

Wow! This stuff is AWESOME!The first thing I liked about it is that it once you add the water and put in your pots...it;s not messy like the soil you buy in the bags. I added the gallon and a half just as the instructions indicated, and it turned into this easy-to-use, nutrient-rich potting soil.The only question I have is if I can store the extra and use it later...will it re-hydrate well and be usable? I'll come update this after I try it.

I have worked in greenhouse, owned 2 floral shops and a green house for 30 plus years and this is the best seed starting product I have ever used, package looked sort of small untill I opened and processed it, HUGE amount when wet. my geraniums were up in 3 days. 100% sprouted, lantana, gerberas, petunias, rudbeckiaalso up. no bugs or mold

Looks like standard compressed coco coir, but the thin plastic had torn during shipping so some of it crumbled off and had to put in a container right away. Not a big deal but for a brand that tries to look sustainable they should think about using something other than plastic wrap that doesn’t function well

This coir is the best value I have found in coco coir. The price is right!I mix some of it into the soil of everything I plant. Here in super-dry Arizona, the water holding properties make the difference between thriving plants and pathetic plants. I have to water less often and it keeps the soil more consistently moist but not too moist.

Wasn't sure what to expect from a compressed block of dirt, but when you add water, it REALLY expands. I used it with some castor seeds, and 44 out of 50 seeds have sprouted and are doing great in this soil.
