as above what does everyone keep their rooms at? I've always been around 25-26* when useing hps but now useing the cobs and boards what should it be kept at? My whole room is pretty equal just drops off temp wise a couple of degrees at the bottom of the pots.

Just wondering what's gonna grow me the fattest buds?

I suggest you raise your pots off the ground so the heat does not get sunk. It really takes long to get the bags up to temp with LEDs, you don;t want to sink that right back into the ground if it gets too cold. Kinda regret I didn't do it this run as it gets a little chilly overnight here now. My suggestion is for the cold part of the year run DWC or aero, and when it gets hot do coco or soil outdoors. Aircons are fun but they chow a lot of power. My 8" extractor does a fine job when things get a bit muggy.

I've always been told by experienced growers that an ambient temp of 28 is good. It is important to keep the roots warm now that winter is arriving. It's a good idea to have a thermometer at pot level to monitor this. You could also have another at canopy level as well, just to be sure that it isn't too warm as the heat rises.
Hope this helps dude.

P.S. I have a large CFL that I use in winter that warms the space up as well as providing a little extra light :)

The highest it's been is 30* when we had a 30* day so I'm good on that part and keeps 26 overnights get when cold at night. Pots are off the ground on iws drain trays

28 you say? Ok I can try that. I have a thermometer on the floor, a minder from pl grow systems with temp and humidity read in the canopy and also a probe above my light then I have another I can switch between c/f that hangs in the canopy loo

I have 24.2 on the floor with 26 at the canopy

Leaf temp 23-25*!on the few top ones I checked is that about right?
Yeah I think that is fine. I was always told not to let the temp get below 20/21 at pot level, so your temps sound good to me! Above 30 anywhere in your grow space starts to be a problem I believe.
