Both substrate bags are full of high-quality, sterilized ingredients ensuring a contaminant-free journey. Millet grain is perfect for the colonization of mycelium as it is much less prone to contamination than other more traditional grains, i.e., Rye Grain, and quicker to colonize!

Monotubs are best for more experienced growers as they need a knowledgeable hand to support them during the fruiting process. If you are a beginner and are looking to start your first kit, we’d recommend our all in one grow bags.
Using our pre-sterilized grain bag and CVG is not only easy, but will save you time in the long run! This kit is widely used and reported to yield larger, more abundant harvests. To ensure your kit goes smoothly, please use our provided guides you can find here.
