@EDDIEKIRK thank you for that. The perlite is a good idea for me because im on a budget so making the medium stretch further is good. One thing i'm wondering, if i was planning on planting these in the ground (using a tire to house the plant) would there come a point where the roots extend into the normal earth and the grow medium becomes irrelevant? I have no idea if this is how that works. Also, say i bought fox farms, do you need to use nutrients? or is water fine.
