Auto flowers no, but the set up won't likely work for a photoperiod.

6" c' filter adapted to 4" Cloudline fan?
Has anyone mated a 6" carbon filter to a 4" inline fan? AC Infinity is OUT of 4" filters, so considering getting a 6" and adapting down to 4" intake on AC Infinity Cloudline. Seems intuitive, since reduced intake restriction would be preferable, with increased life as a benefit.

High heat in greenhouse, how hot is to hot?
I built a 16x20 greenhouse with dual vents and a 24” exhaust fan. I hit a max of 122 (it’s 92 outside). I typically reach 105-110 on regular days. Everyone looks happy other than an nutrient burn issue. Can weed plants handle this kinda heat?

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

Ventilators OFF/ON
Hi, guys. I have one more question today: - My box has three ventilators. One is working in the upper air channel all the time to bring out hot air. Other two staring on my plants. Should I use all three of them? Or one is enough till my babies will grow thick to pervent mould?
