Passive air intake is the easiest way to go , and I just worked my Vapour pressure I’m doing really well if im to go by the chart iv never looked that far into it glad I did now ,Air flow so important.
I was reminded of that two weeks ago with a mold outbreak.
Ive been also studying the vapor pressure deficit chart. Incredible how much can go wrong with the tent environment.
Ok so I switched to 400w MH 12-12 today and added a mini pro co2 bucket and a humidifier. After turning my light up I ended up with a temp of 104 and humidity of 37. I’m trying to pump in some cold air and boost humidity. I’m also running my light at night and letting them sleep during the day. The light was at 50% now it’s @ 100% there is a 75% setting if I can’t get the heat down maybe I’ll have to turn it back a notch.Hey Louie,
so that’s largely up to you. The bigger the plants the more places for flower to develop.
however if you are running out of head room in the tent I would switch to 12/12 lighting sooner rather than later. In the first 2 weeks of the bloom process your plants will grow 20%, its the stretch before pistils form.
I have that chart. I think I got it from the last time you posted it.Wow 104 is hot. this might be the most useful chart to use for growing. Def try to drop the temp or raise humidity. I also run lights at night. Helps with opposite warming affects in the winter.
