Did the 14 day trim of foliage on the bottom canopy to get rid of the unnecessary leaves that I could. I figured out the best way to manage VPD and keep humidity in range was to set the AC Infinity controller to VPD mode (was in cycle mode and that worked until the plant got larger) and turn on the fans higher when I wanted VPD raised.
I also returned the in tent dehumidifier I got from Amazon. It had functionality to set humidity and detect temperature, but always detected temperature as 99F and humidity as 35 RH after being on for 5 minutes. I could put it in always on mode and control it with the AC Infinity controller, but that used a UIS port unnecessarily. Plus the new one is large enough and strong enough to dehumidify the lung room, which has been game changing for me so far. I eventually drained it outside, as the reservoir was smallish for how strong of a dehumidifier it was and I had to empty it at least twice a day.
In the lung room, the dehumidifier is set to 50% which it gets the room down to and holds it pretty steadily. I also added a duct splitter to the intake hole at the bottom which now blows air around both sides of the grow container instead of directly at it. This seems to have to have increased air flow immensely. I can basically get VPD as high as I want it, even went too high (1.6+) a few times in my trial and error periods. I finally figured it out to fan speed 5 when VPD goes below 1.2 and fan speed 2 once it gets to 1.3. It will stay at 2 until it drops below 1.2 again. At this setup, VPD doesn't go above 1.35 or below 1.1 normally, and usually sits around 1.22-1.25.
At this point I am watering 1 gallon every other day and feeding twice a week. The soil is dry according to touch and moisture meter after about a day and a half, but I've been pushing it to 2 days to avoid any over watering issues.
The Cal-Mag amount is for only one feeding per week, the rest of the nutrient amounts are for both feedings.
All good things come to an end! This next week will be the final one for this girl. It's been fun, can't wait to do it again! But ready for harvest until then.
So it was pointed out to me that while my phone has a macro lense, I was using it wrong, so now I have better pictures of trichomes for the this week once it is over.
It's a waiting game of is she ready now I guess? I'm hoping the temperature issue didn't cause anything major. It was about an hour before I noticed. The leaf colors are kinda of concern for me, but the rest of the plants looks okay otherwise. Trichomes are mostly cloudy I think 🤔. It's honestly hard for me to tell.
Slight discoloration in the leaves, which I'm attributing to overfeeding Open Sesame and Beastie Blooms. No other issues observed so far. Some lower leaves have fallen off here and there, not no major issues that I've seen.
Intake fan and filter were added, have AC exhausting outside rather than into another room. Next week I will be exhausting the tent outside the room as well. VPD is now dialed in to the range I set and never gets outside of it. The AC automation isn't working properly and I have a request in to that company, but in the meantime, I have alerts tell me when the temperature gets too high, then I manually turn on the AC and automations work for a day afterwards.
She's growing out more than up. Going to install an intake fan and get it going with the exhaust fan, as well as exhausting outside instead of in the room the grow tent is in. I will probably move the dehumidifier to this room when that is done since I'll (in theory) be able to use that room better to regulate grow tent conditions.
Humidity has been going up during lights out, humidifier is on the way. It only gets down to about 65 at the lowest at night, but the 5-10 degree or so drop is enough to make the humidity shoot up, which in turn throws the VPD off. Hopefully the dehumidifier resolves it. Will update at the end of this week.
