I keep my host plants in 1 gal containers. Lots of bonsai/LST and regular haircuts/trimming keeps them well under 2' tall. I toss 4-5x as much as I actually need for clones. They have been in the gallon pots a bit over a year.
After a year or so when they start getting gnarly, I'll start new moms, transplant the old ones into 5gal buckets and flower them out. Works well for me.
Been running the same strain going on 3 years now.
