9 clones, 400w HPS, SOG,!!!!!!!!!!!!!!

right now i have 2 plants finishing under the 400w and a 3rd bush about 2 weeks in ((couldnt veg longer so i had to put in flower)) when these 1st 2 finish ill put the bush in the back ........

SETUP: 400w hps HTG supply homemade cool tube. 6in and 4in inline exhaust. 6" right at the start of the cool tube and the 4" at the under end of the ducting. the 6" alone wasnt enough temps are now 90F for about 2 hours during lights on. rest of time around 85F.
9 clones in 1 gallon pots strain: 2 train wreck, 7 dank bag seed. pro mix soil and mirecal grow nutes.

my main quetion was if 9 plants was an alright number and how long i should veg them (if at all) to maxamize my yeild please help me guys im just waiting for 3 more clones to root +rep

((sorry bout all the spelling error's))

If your'e doing 9 plants, I would say veg them to around 10-12 inches and then flower. If you did some LST and a few other things, you'll get an even better yield too...

oh ya i forgot i had a trelis i wanted to put up as well do a scrog sog. probly not fill the hole screen sense it is a hole 9 plants but 10" alright anyone else got info or got something else i can do to improve. im moving in may so this will be my last harvest tell i can get set up in new place thanks and +rep meezy

9 plants might be a couple to many for 400 watts. i would veg them for one month then flower them should make for a decent yeild 1/4 to a 1/2 a pound

thanks looks like thats wut im doing a month veg should be around 10" thanks guys
