Dear Bargavn,
Mushroom cultivation, in its first place is not a Home made business. You can surely do the cultivation in your home, but only for your self consumption or hobby cultivation. Since, planning a large scale cultivation, will require good space and at home, it will effect the structure due to high humidity, you need to maintain during the growth process. Please, do consult, someone, who is an expert, before you decide on your place of production.
In case, you are planning in a small quantity, try to sell it in your locality and as you grow, you can target and tap your market.
Thanks
