I should add I'm not ready to put a space heater in there yet. And I accedentaly said circulating fan. More correctly it's an oscillating fan, that's blowing over the canopy that I am thinking of turning off.I used to have a fan controller variac thing to slow/speed outtake in emergencies, also a heater on thermostat plug
Air is just coming from another room but heat is not on. So the oscillating fan is just blowing air around not in or out of the room, and it's directly on the plants. The in and out fans don't blow directly on the plants. I'm thinking they don't need the wind on them when it's a little chilly.Is your air coming from outside? There are a few things you can do

Well you could try turning that fan off and have passive air from same room and see if temps get warmerAir is just coming from another room but heat is not on.
What light source? If using LED these cool temps will kill growth rates and yields.There is a slight chill in the room, aroud 71 F is the high. Would it be better to turn the circulating fan off? There are still in and out fans on. rH around 55%. Plants in flower. Thanks if you know!
low so far is about 68F. so that's kind of perfect right? it's probably a litttle hotter under the lights too so maybe i shouldn't worry.what's the low? that's an ok temp to be at in flower if it doesn't drift too low. I'd rather have it little cooler with air circulation, than a degree warmer with no air moving... the fan wouldn't be cooling the room much at all anyways, just moves the air around.

they're HID's. I leave the input fan on because the dehuey is in the room it pulls from. I might set the dehuey a little lower too since yeah, it seems to be having less effect. i didn't realize that's probably why!What light source? If using LED these cool temps will kill growth rates and yields.
With cool temps RH% can become more of an issue as the air holds less water causing RH% numbers to be higher with the same amount of moisture in the air, and is harder to dehumidify.
older non-digital 400W MH and HPS with ballast attached so they're generating some heat. oscillator moves that heat off the canopy somewhat. it's a bit of wackamole because if i fix day temps it will mess up night temps and vice versa. for now i want to get to on average the best levels i can, knowing that it won't be perfect but for now the best i can get with what i got. i hesitate to turn on the heaters as it's going to warm up again for a while plus the heaters generate light and that's a whole thing i don't have time to fix right now.I would want those temps up around 78-79 probably, what types of HID? Wattage? HPS, MH, CMH?
yep, tried a few things but got down to 65/48% low, 71/52% high. Would like the colder night to get some color but not getting enough heat on the high end right now. Back to looking at more space heat control. I guess maybe it could pay for itself. Also gives me a new question of just how bad would constant 76F day and night be?I would want those temps up around 78-79 probably, what types of HID? Wattage? HPS, MH, CMH?
Better than this cold stuff. It kills yield by slowing the metabolism. You want warmer leaf surface temps when the lights are on. Cold plants equals slow growth and reduced yields. Cool nights give purps because of limited phosphorous uptake due to cool roots, also hurting yield. It's ok to do that during ripening, like the last 10 days or so but do it too early and it's hurting yields.Also gives me a new question of just how bad would constant 76F day and night be?
I better get on it then. Found a heater I have that doesn't seem to make light so I'll try that. Thanks.Better than this cold stuff. It kills yield by slowing the metabolism.

I tried 2 more things.I better get on it then. Found a heater I have that doesn't seem to make light so I'll try that. Thanks.
It's not a tent so lots of air leaks but I gotcha. I more or less point the circ fan at the lights. My exhaust is already at the top because usually too hot is my problem. Already playing with fire (old lady) cutting holes in the wall, so I gotta think i won't cut another hole. I'm going to try blowing air in from the other room (hole already there) which may make the dehuey work harder again but it would be a little cooler. Wish the can fans were better. I think an aftermarket speed dial fucked up my can fan and I took it off and now that fan takes 24 hours to come up to speed.Point your fan at your light and blow downwards, exhaust the air from the bottom of the tent, play with the speed until it’s nice and warm
