if u worried about space untill your final harvest (so u can decide keepers) you can take clones and keep them under 24hr light it slows them down from stretching because they don't get off time to stretch I do it and keep light a cfl not far away and just water after rooting to keep them small no nutes or root enhancers it normally keeps them small for long enough iv had to do it a few times and use a card board box and 2 cfl a 6500k and 2700k I had 20 at around 2 inch for around 6-8 week lol in solo cups untill i could decide hope it helps
