It was a pretty explosive week of growth. She started showing signs of pre-flowering towards the end of the week, so I started feeding FF open sesame.
Temperature settings I figured out on my portable AC, as well as set it to dry mode to control the humidity and have automations setup to turn on/off in the lung room. On above 75 degrees and off at 66 degrees during the day (down from on at 77 and off at 68 at the beginning of the week) and this keeps the tent between 69-79 degrees. At night, I turn on above 72 and off at 63, since it is very humid at night here. At night the tent is 66-75 degrees. RH during the 24 hour day is between 52-65% and my VPD is now set to dehumidifier on at 1.1 or below and off at 1.2 or above, trying to maintain a VPD around 1.2.
Watering is .5L and needed every other day at this point, and feeding twice a week. Following the FF feed schedule here: https://imgbb.com/sJ8mfWT
Can't wait until next week. Will be switching to 24/0 light schedule because humidity is still getting out of wack at lights out and I don't want to deal with humidity spikes during flowering.
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.
