First timer I’m struggling with the temperature and humidity when my 2x 600w HID lights come on.
Set up: 1.2m x 2.4m x 2.0m budbox lite tent
2x LUMii black grow lamp with euro reflector
Ram 6” mixed flow inline fan (extraction)
Rhino carbon filter (extraction)
4” inline fan (intake fresh air)
9” oscillating fan
6” fan
Water cooled air cooler
Humidifier
I have 5x 12L pots under 1 light and 3x12L, 2x16L pots under the other light all with autos in so running 18-6 light schedule. Plants are 10 days old they look good so far lights are 3ft away from plants. Temps are getting to 30-35c for first 3-4 hours after lights on and humidity dropping to 30%. Temp is only 23-26c above lights. Thanks

Im not sure if your extraction may be powerfull enough for them 2 lights i used to struggle with a high power 5 inch in a 1.2x1.2x 2.0 with 1 600w hps and i ended up using a cooltube and i was glad when i switched to led as them temps your getting arnt going to do you no favours and hopefully someone else can tell you if thats your problem

Would I be better getting another extractor or just a more powerful one? Temps were fine when I only had 1 light on, I was thinking of cutting it down to 1 light and only 5 plants but I can’t bring myself to get rid of the other 5 hahah

let me tag a couple of others in my growbro @Trichome farmer @Mañ'O'Green @Arthur @Nosias @arty zan I'm pretty sure one of these can help also @Dabber @hairyman as i know one of them will know for sure about extraction

Prolly of no help what so ever but my notes indicated i needed two 5 inch fans for the space you have if i went with hid's.
I went led and smaller tent but id written in notes with some numbers (guess there is a sum i cant remember to work out ideal airflow).

If you are running air cooled fixtures vented to the outdoors and it is still too hot you can add AC to the room or change lights to LEDs or like you said only run one of them. I use an 8" exhaust fan in a 3x6x8 foot space and in the heat of summer she runs ~75% of maximum with 700w of LEDs.

my buddy runs a similar set up to this two 600s he was hitting 32c in the summer so we got him two air cooled tubes/hoods dropped the temps down to 28c not ideal but best we can do in the situation if your not venting the hot air outside of the room where the tent is you wont get rid of the heat to keep the humidity up for younger plants you will need a humidifier

It’s set up in my loft, it doesn’t directly extract to the outside it’s about 2m away from soffit boards but there’s good air flow in loft. I have another humidifier coming next couple of days. Did your friend get a separate extractor fan for the cooled tubes or use existing fan? Thanks mate

I think you definately need another extractor. I'd say you always one extractor per hps per 1.2m tent as they run so hot. Try another extractor if you can or even the cool tubes too. I've run a hot grow before, 32+c, so hot I stopped monitoring. I was stressed the whole grow but the girls did fine and I had good meds to smoke for my troubles at the end!
