Hello growers,i have 2 questions
to ask you,first one is - Do i need to add extra perlite to bio bizz Light mix when growing autoflowers outdoors? Second question-Is it good idea to place some hydroton on the bottom? Thanks in advance!
Extra perlite will increase the plants tolerance to overwatering. Root like air as much as water, and nutrients. If your area is prone to heavy rain at times It would not hurt. I usually place grow stone at the bottom and in the mix some. Same concert differ material.
