but per light?

PTAC- Packaged Terminal Air Conditioner (The big 240v A/C-Heater things sticking out the wall in most hotel rooms) The sleeve is just that, a rectangular metal sleeve that goes in the hole cut in the wall, and the PTAC unit mounts to/in the sleeve.

Having seen these in junk yards, they run both heating and cooling- with water. The unit supplying hot and cold water is still required, and can be a heat pump.

This is at a very basic level similar to what I'm working with- only I've separated the hot and cold a bit so that cold can also dehuey.

That's more reason to add lights if this is his lively hood and not a hobby. If adding lights is going to increase his profits in the short term then he should do it.

If adding lights won't increase yield and risks adversely impacting quality, then it won't increase profits. Therefore, he should NOT do it. Control your environment first, then expand. I learned this the hard way...

Like ttystikk said, use that cold outside air to your advantage while you can. Of course I agree with mini splits being the best choice, when your situation doesn't work for one, it doesn't work... so if you don't want to get too technical with it, there's these variable transformers (aka variac) that you can plug your intake fan in to. They're like fan speed controllers, but rather than turn the motor off rapidly over and over again, they change the voltage to your fan to slow it down, so you can adjust the speed/cold air you need to pull in, no risk of motor damage. Another plus is they actually quiet your fan down. I have three, used one for over 2 years in one room and the second for a little over a year in another room both with Vortex 6" inlines, no problems, each turned down to about 75%. The third is on an Active Air 8" duct booster fan for another room around a year, at about 80%.

These are the ones I use:

Hold on here folks.. I seem quite the over simplification of co2 use going on. Temps of 90 neccessary? Ummm no.

While it is true that higher temps boost a plants metabolic rate which enables then to take advantage of higher co2 concentratuins, advising a somewhat newb to set it and forget it at 90 is, well, it's just not good advice.

Optimum conditions change throughout the growth cycle and day time temps are just one of the factors, nighttime temps and more importantly, the difference between the two is equally important. If your room is at 90 then your plant tissue is likely at 95. It's just too hot.

Those temps are good for veg and maybe the first two weeks of flower but unless your having hotter nights, your going to get some major stretch going on.

I'm not going to sPell out the ideal situations for all phases.. I mean, it took me YEARS of research, trial and error. And then inevitably some jack hole will just say nuh uh. But needless to say as flowering goes on, your temps and co2 lower. We are at 77 and 800 during the bulk up phase and 74 and 600 during maturity.

You could run 90 degrees all day long and nothing bad is going to happen, but in terms of bud quality...nothing good is going to happen either.

Peace

by adding lights you add more plants thus increasing your yield... i dont see how thats unclear...

wheres the evidence that co2 and high temps effect bud quality in a bad way?


also as long as you do not go over 95 in the canopy you are ok..at 1500 ppm co2

Your rude and cocky attitude does not serve you well. Where did anyone say anything about 90 degrees at night and setting and forgetting at 90?

 

[legallyflying]

My rude and cocky attitude serves me just fine actually. Especially with hack growers dispensing bullshit advice. 90 degrees is "preferred".

Uh huh, show me a link to someone other than a keyboard hero saying that.
