growing, but short on time

so i just started a grow about a week and a half ago(5/26) from clones, but i'm moving out of my place at the end of july, giving me about 7 weeks left to grow. i'm wondering what the best lighting plan would be for the rest of the grow. right now i'm giving them 21 hours of light with a light amount of nutrients and theyre growing pretty well. Should i start flowering them now? theyre not very big yet so i dont think the flowering process will take as long as usual. i'll probably be able to dry the plants wherever i move to, but i dont know if i'd be able to transfer live plants or have a good setup. what do you guys think i should do?

sweet, thanks i think i'll switch them to 12/12 in a day or two depending on how long i want to keep them in the dark. good news is i'm growing two indicas with a 400w hps. do you think if i get the light closer, it'll help the plants grow faster? right now i have the lights about 20 inches away, and i'm afraid if i get them closer they might scorch the plants cause theyre still kinda young. if i placed a revolving fan between the plants and light, would i be able to get the lamp closer?

The only thing that has been proven to reduce flowering time (slightly) is to give the plants a 36-48 hour dark period before 12/12. This can shave several days off flowering time, but at the expense of end yield. This method also carries a slightly increased hermie risk.

Another (experimental) method i have heard is to use a non 24-hour cycle, for example 6/12, for an 18 hour day in total. This would require a 7-day timer, which would need regular adjustments. Some people say they have heard of others doing this successfully, but I have never seen a documented grow with this method myself, so try it at your own risk. At the very least it will reduce your end yield, if it works at all.

yeah-turn them right away on 12-12.
