So i went and got a new ac got my temps down to 26-27 daytime under lights and 21c during dark. girls are looking good other than some slight nute burn. Littlest one still vegging at about 6inches. tallest is 16in. just raised my hps to 20 inches from the closest plant because of some leaf edges curling. All seems well atm.
@Dunk_Junk,
I switched awhile back to electric. my 1000w is on 75% and my 600 mh is on 100%. i did run my 1000w on 100% 24h a day and because of that i was using "prime" electric hrs which is like .20-.30 more per kw. my bill was litterally double wat it was when id have it on 18h. and just doesnt make sense electrically to grow on 24h for me.
@Sggtfghkirer, If you're still using HID you need to get some digital ballasts instead of the old magnetic ballast. I did a test, my old 600w magnetic ballast was pulling WAY MORE than my 'new' 1000w digital ballast.
