Our premium horticulture vermiculite is simply the best grade and variety for mushroom growers. Almost all vermiculite sold in local stores is very coarse. It's hard to use properly in the mushroom growing process. We use only medium course Sun-Gro Premium grade Horticulture vermiculite in all our products! Vermiculite absorbs water and is a key ingredient in many aspects of mushroom growing and fruiting. Vermiculite is a popular add on to almost any kit or growing project.
