Nice and bushy you can see an ever so slight sign of heat stress but coming along.day 41 veg pic
10 1/2 inch tall
top leaf temps have been around 80f with 55% (playing it safe because it's so warm)
soon upgrading the carbon filter & exhaust fan to 8" + 40" standing oscillating fan.
i soon will be turning on the cob leds when it's already warmer than i'd like
Agreed! A little tender on some of the top growth.Nice and bushy you can see an ever so slight sign of heat stress but coming along.
Yea daytime hotter. You are getting humidity spikes after lights out... You want to get this under control or you will have to lower your overall humidity to compensate. You could try lowering the temps slower at night. nice and even so farpics taken for a while of lights on. with the new exhaust & way for me to graph the RH & temp, i'll be able to set a schedule on my thermostat. 10 degree F difference from night & day, right? daytime hotter
@TacoMac thanks for pushing me to do some research! according to the attached chart, VPD is better at measuring than RH.

basically, for optimal leaf transpiration i need to be in the green for optimal potential.
i'm not seeing any condensation form on the leaves.
Really good example of how temp affects humidity. Looking good thoughday 50 veg
i read that light stress during flower can cause plant stress that can appear as nute deficiency.
i moved the light up from 24 to 28 inches since there's some signs of cal/mag deficiency even though i'm using calmag. also some light bleaching, oops!
she's only 9 inches tall,
super compact node spacing
i've already had to do some pruning so the leaves aren't sandwiching.
i intend to veg her for another 2 weeks then flip her
Agreed.Really good example of how temp affects humidity. Looking good though
