Innit paulie and all is good at the ranch.
So, fan at top of tent into cf outside of tent meant Temps at 30c with a 250. = No.
Bit of ducting under the light and trim the ducting into CF. Tested at 600watts, temps at 29-30 in mid sunny afternoon. Im happy with that. Its amazing what a bit of repositioning of extraction does for temps. Loads of neg pressure in the tent and its heating the whole house
Have given them a bit of dark as they have been on 24/0 since they put their cocks out and settled them into the 600 today and they are growing quickly now. So will do them on 20/4 with lights off 12-4pm i think. That should work fine with the 600. ill top up the pots with soil tomorrow and take off the single fingered leaves. clip on Fans not arrived so next week it is. But not too worried about that.
