this is my growtent setup!
i have 20 whitewidow seeds
im planing to run about 16 plants inside!

so guys its my first time and ill gladly hear what you think!
sorry no pics since i dont wanna start doing something wrong.
please share your opinons, will i need something else or im ready!?

i bought whole complete for US$ 753.4!

i have problem with temperatures, 28to45C and 10to26deegres, please help!!

What size of fans are you runnning? That tent is going to need some major extraction with a 600 in it. Are you sucking air through your cooltube and out of the tent?

45c Yikes! That's about 110F. Need more info, is that fan just for the tube? Is that the only fan? If so is that hot tube air getting out of the tent?

i just started my first grow, i think i still have problems with temp, 17to27C and 28 to 45RH for now its my second day ill post more info and pictures soon, please need some advices should i go up or down with temp or rh and how i can do that, im sucking air trought cooltube and also running 1 big ventilator inside the tent.
