When should i put my clones under 1000 watt hps sodium

Im picking up my clones in a couple of days from a clone nursery by my house.I have some t5 enough for the 8 clones im getting,I know they will be ready to go with good root structure already.So when can i put them under my 1000 watt hps and can i use it for growth stage.I was going to let them get 12 inches high before i switch to 18/6 but im not sure if i can use the hps for the growth stage.If i can maybe i will bet a couple more clones when i go.And if i do use it will they grow faster under the hps or is it to much for my little babies.

Depends on what bulb you using. If it is a dual spectrum bulb you can use it right through your grow. I put my week old seedlings straight under my 600w hps with no ill effects. If the clones are well rooted and healthy, i would give them a week under the t5s then put them under your hps.

You could potentially grow (veg) with the hps as long as its not set on a 12/12 schedule. If you're looking for bigger plants, then veg until you get about half of the height you want, because once you set the timer for 12/12 you'll usually double in size by harvest. I just wait until my clones root and I throw them into flowering without vegging at all, works great

If i put them right into flowering how much less will i get when i harvest.And what about the nutes would i just go directly to week 5 or 6 on the foxfarm growth chart.And how tall would they reach and how much bud do you get of one plant after its all dried.Sorry for so my questions but i would love to got straight to the flowering stage if it works better.

sry to hijack on this but i was wondering the same question... after my clones showed rootsi took them outta the humidor, planted them in soil and imedeatly put them under my 1000HPS... within hrs they were dead... should i give them a few days outta the humidor under a CFL or somthin?? how long b4 i put them under the 1000???

Let them get used to it a little at a time; a couple hours the first day, then half days... just as you would if moving them outdoors.

Once they're acclimated, and thriving, go 12/12
