Review: Extra fluffy! - This is excellent coco coir. It expands to an airy and light product that works great for both seed starting and bends for potted plants. The water runs through it quickly but remains full of moisture. What makes this particularly good coco coir is the expanded product is an especially fine grain, extra fluffy, and spongy (compared to other coco coir I’ve tried). I generally prefer coco coir over peat moss for both ecological reasons and the efficacy of coco coir over peat moss. This is particularly good coco coir and after using this product I don’t understand why people even bother with peat moss. Peat moss can easily dry into a solid bricklike substance whereas coco coir (especially this one) remains airy even if you accidentally under water. Since using this product there has been a noticeable improvement with my microgreen yield, my potted plants look happier, and the price point is reasonable. I’ve purchased this multiple times now and have been very satisfied every time. The only issue I have with it is it’s a rather large block and a bit of a commitment when you expand it to 15 gallons, but that is probably part of the reason it’s priced lower per volume than other products. To help avoid mold during storage I dry the expanded product in the oven on a low temperature (no hotter than 180 F). Higher temperatures release toxins into the soil like ammonium which are bad for plants so if you do this, keep the oven no hotter than 180 F. Then I combine it with 1 part vermiculite for 6 parts coco coir for an especially fluffy grow medium.
Review: Perfect! - Fantastic for growing gourmet mushrooms! Does not have additives that would be harmful for a grow, which is a relief after having a huge trichoderma disaster with another brand! Plus, the discs are the perfect size for fruiting a colonized 1qt jar! Very convenient :)
