need ur advises....pls

Hello evryones,...
Nice to meet u....im Julien...
Had first time indoor grow , twenty years ago...an now re trying...
Inside steel cabinet, which sizes are...80cmLx 150cm height x 45cm wide, for space reason...
Insi have aeroponic system 5 pots,
250w hps with ''upgraded' lamp at 37k lumens, extract 400mph, (carbo filter) with temperature control, intract with small computer fan. Temp . . 24-27c , day, and 19-22c at night...humidity , was too low at 20%...and I ve added humidifier to reach now 35-45%...
TWO sprouted seeds....liberty haze, and critical 2.0...
Both have first root come out from root riot and rocwool...(Iwant test both,)...
I v read this is maybe too early to put in the aeroponic system....???
I ve set up watering 3min/1,5 hour...
Is it correct ??

Pls give me ur advises and tips, as it is first time aeroponic...

Leave the pump on 24/7. For optimum results, a plant's roots need constant access to water. Reed this for better results in growing cannabis using aeroponics.

Hi,
Thanks for ur reply and will follow ur advise from tomorrow.
Critical 2.0 has grwoth much vigorous than libertyhaze until today...6-7 internodes and only 4 for haze...?!
As my height is limited, imtrying to lst, and will start scrog by tomorrow.
They are at abt 21 days old, and plan to start flowering on or abt 28-31days...
Do yo think they continue grow and will will screen for how long time ??
I'm worry to have or too small canopy or overcrowded...
Pls give me ur experience if u have. Thanks
