BonjourDo you run CO²?
CO2 is use mostly to help plants with the heat generate by a 1000w...I guess you don't need it with cobs!

I disagree with this. CO² is widely used in Colorado's commercial growing facilities to significantly increase yields. I'm curious about how it interacts with COB LED.Bonjour

Hi, I would love to improve my growing.Bonjour
And it is the first time I am concerned about cold in the growbox...in January it is cold here (lots of mountains around French Riviera...full of snow...5ºC right now!) But I still have the 600hps in the 4x4 next to the cob so for now it is ok...but when I am going to replace it with cob too...I guess it is going to be...removing the fan on the drivers when it is cold and put it in to heat the box...
I never had this problem with hps...lol!
@bassman999 why don't you start a grow log? We could help you this way...!
I am sure you could do much better with a little help!...no?
I grow since a long time and I always pull between 440gr and 530gr from a 600hps (30d vegg and 70d bloom generally) way less in 2000 when I started indoor with WW...
I know many things about growing plant but there's much more I don't know...you have to stay humble to progress!
I know a guy who was a god of growing...he is stock in 2000...no improvement since...I told him since years that they are many new system and techniques to improve his grow but he is sure nothing is better than his setup...and he laughed when I spoke about cob..."only hype" he said!
Let me finish my bloom and show him the results (it is going to be hard he work where he live and never stay long far from his ladies...)he gonna be shock!
Have a great day ★
Huh? CO² doesn't increase heat unless you're running a CO² burner, and all the literature says that raising temperature in your growroom is the best way to fully utilize CO² supplementation.One of the reasons I have not pulled the trigger on going with CO2 was the heat generated by my HID's. Now that it appears that even with 12 COB's blazing my room's temps went up a whopping 1 degree above ambient temps in the basement.
CO2 is now a viable option that I will be taking on in the months to come.
Ahhh, I'm totally with you now. I haven't been able to run CO² for the same reason, until just now with my new heat pump.It's the sealing of the room with 1200 watts of HID's that causes me hesitation about CO2. I don't have the ability to run a splitter and the portable A/C I have sucks. My temps last summer WITH intake/exhaust venting hovered around 100 degrees.

@ttystikk do you have a link please!
25% more by increase the heat at night...or the 12h plants sleep!? Do I get it right!? Because nothing easier than switch on a little heater!
Have a great day ★
I believe this too, with some limits. Therefore, I don't plan to raise nighttime temperatures very much at all.My belief is high temps are the enemy of quality and affect the flavor and smell. Limo,did you notice this when you ran higher temps with CO2?
no....don't 'learn' it! make these people utilize units that make sense!Bonjour
So what you gonna do...26ºc days and
28ºc at night? (Sorry not easy to remember ºF...I do with feet and inch now I have to learn ºF and oz...lol!)

Freezing is 32F, then 180° later, 212F is boiling.Bonjour
Lol!
Just a question...how many ºF is boiling water and ice?
What is 0ºF and 100º?
Is there something under oz?

Generally, the chiller is the single most expensive component. You need not get a big one if you do your diligence with tub insulation. I realized that I wanted to use water for ALL of my environmental control needs, so I bought larger units to replace AC.Most expensive part of any hydro is usually the water chiller no? I keep wanting to do some sort of hydro/aero but am intimidated by the res temp.
