Dust Shroom Greenhouse Use

When cultivating using a greenhouse made of transparent material, such as glass or plastic it becomes abundantly clear that plants require regulated climatic conditions - and to that circulation and fresh air are KEY! These structures range in size from small sheds to industrial-sized buildings but all require airflow and can be easily outfitted for Dust Shroom Filtration.

Dust Shroom Indoor Use

When you grow indoor with artificial lighting, you can better control the quality of the material by controlling the conditions, manipulate the growth cycle to harvest more frequently. You can grow year round regardless of conditions outside but that also means that you have to bring the air from the outside in - and to that circulation and fresh air are also KEY!
