@Med_in_Tropic, I used it with my French Cookies plant to improve the soil because it was compacted at that time, so I added some organic matter.
There was one plant that had curled leaves, but I'm not sure if it was due to the seed's viability. I've never used it for plant recovery before.
@kitzeed16, I just tried using it. When I bought it, the seller asked if I was growing cannabis, lol 55555. What brand is good? The prices are all over the place, I'm confused looking at them.
