I am a hempy grower...

A "hempy bucket" is just drilling a hole 1-2 inches from the bottom of the bucket to create a mini reservoir, yeah?

One could feasibly use any medium, perlite, vermiculite, soil, coco fiber, crushed rock wool, worm castings, etc or a mixture of some of those

My next grow is going to be 50/50 perlite and Fox Farm Ocean Forest I think.

See, I am no po.

The HPS sounds nifty. I am just going CFLs I think, but yea 75 F is where I am going to keep temps as well.

good luck and keep us updated bro

peace
