You can use whatever u want man just make sure what ever u pick u know the pros and cons are. Im on my first grow and im went with 100% perlite and hempy bucket. What a hempy bucket is is that u measure 2 inches from the bottom and drill a hole in the container. So whenever ur watering the bottom will get filled with water and anything over 2 inches the water will flow out. Its kinda like a soil/hydro grow bc wwheneverthe roots stretch out to the bottom they start growing reaaaaallllllly fast!
Thanks for this comment man you really made me look into hempy buckets and wow.... For the past few days I have just been researching about them I have come to wonder why everyone doesn't use these things.
Nutes, ph pen, 4 inch exhaust blower, perlite and a few other bite and pieces have been recently bought and are on their way. Once the fan gets here I will begin to prep the fridge. This project should hopefully be underway within a couple of weeks.
I was also wondering if anyone knew how many plants I could fit in my fridge with a 250hps? I was thinking I 2 plants would be optimal for my space.
