Hey everyone im new to this threat. So here is the deal, i am not a new time grower. This would be my third grow and im working on making it big. Prior to this i have done a closet grow under a 600W hood lamp with not so good air flow. I will be turning over to a 1000 Watt lamp in a 8x4x7 grow room with ventilation and good air flow. What i need help with is a good suggestion in what kind of soil and nutrients to use. Also anyone that is familiar with thc bomb to let me know if i should top it and how many times. I was thinking of using subcools super soil mix also, but im not completely sure if its worth it and how to exactly use it. please reply with any good information.. thank you in advance.
