I'm just going to leave it at this...
I'm sure you are all great growers. I'm sure you follow regimens that were in place long before you've started growing and tailored them to your liking. That's fine. However, there is more to growing than just the "ideal" conditions that are regurgitated.
A cold environment is no different than a hot environment as long as all other factors are addressed BEFORE temp. That being said, I'm no master grower or expert botanist.
I was simply forced into growing in the cold and figured out how to do it instead of throwing money at it or battling it any further.
I'm not saying that growing in the cold is better. I'm not saying it's worse either. It's just another method that provides the same end results. Whatever temp you run, I guarantee better yields and healthier plants if you provide for the other factors before temp control.
Good luck and happy growing.
