So I've got my tent setup and my plants are almost 1 month old. However I cannot get my temps to come down from 85-87 every now and then it will creep up to 90. Although that hasn't happened since I went to 18-6 shutting off at noon instead of 24 hours of light. Right now my ambient temps are 68°F 51% RH. Tent temps are 84° 33% RH. TENT SETUP 4x4 apollo tent 6 inch round fan blowing on humidifer 6 inch 300ish cfm inline fan Vicks cool mist humidifier 6 inch vivosun carbon filter 6 inch air cooled hood 600 watt dimmable hps Small air conditioner piped into the bottom of tent. Lights are 18 inches away with no light burning on the plant. If anyone sees something wrong or a better way to setup my ventilation system please let me know. I'm thinking of taking out the carbon filter until flower and using the 6inch fan to just cool the hood. Any other ideas? I could really use some help. That's my little a/c setup it was able to drop the temps from 90 to 85 but I think that's still to high
Well I might have figured out the problem. I measured the lights and the were only 12 inches away. Note to self use a tape measure everytime job more eyeballing it. I also bunched up a bunch of the ducting and taped it up to try and make smoother bends. I'll see what the temps look like in a couple of hours and let yall know.
that ducting is total trash. if you use that there is zero reason to even air cool your tent. that ducting get hot like a heater . this is what you need what i use . i have 20k watts burning and the ac hardly turns on . Master Flow 6 in. x 25 ft. Insulated Flexible Duct R6 Silver Jacket-F6IFD6X300 - The Home Depot also after you get this if its still warm then just get a bigger blower for that carbon .you should not need to have that fun bringing in the air if your fan on that carbon filter was big enough . how many watts is that hps ? edit i see the heat damage on your plants so you know . and hps is not the best light for veg. if you can afford buy 1 of these . it will save a lot of time in return save you money on the electric bill. there is not need to buy a 150 dollar bulb these will work perfectly fine . replace them every 6 months after 24 /7hours of use .iPower 400W 600W 1000W watt HPS High Pressure Sodium MH Grow Light Bulb Lamp | eBay
I saw your first few words and thought I'm just going to give you uphill for shits and giggles,but I can't man. That Ducting is releasing 60% of the heat back into the tent before it even hits outside. Sent from my EVA-L09 using Tapatalk
what i was saying the metal releases the heat back into the tent . some hot air moves through it but its letting most heat back into the tent .
