Just got back from lowe's and a local feed store. The only 5 gallon buckets I could find were the same diameter as my 3 gal pots. I found some 15 gallon "things" but that's way too big for my grow or grow space.
I'm gonna try to stack em. If it don't work, I'll know better next time. My plan is to fill the new 3gal pots about 2/3 of the way with my soil mix. Then cut about 4 inches off of the bottom of the plant pots with a utility knife. I'll cut the rootball up and place into the new pots.
DP, funny that you mentioned root stimulator. I just bought some
I'll post some pics when I'm done. Wish me luck!!!
