*First feeding last week was 1/4 recommend*
THIS WEEK:
*TARGETS*
RH - 65%, +/- 5% offset (No automations set, statistical only)
Temp - 75F (max low 70, max high 79)
VPD - 0.9-1.3kPa, controlled by automation. (Dehumidifier turns on at 0.9 or below and turns off at 1.3kPa.)
*WATERINGS/FEEDINGS*
First watering (day 16): 1/2 gallon water until 5% run off. PH 6.5.
Second watering (day 18): 1/2 gallon water and Fox Farm Big Bloom mixed at 6tsp/gal ratio until 5% run off. PH 6.5.
*ADDITIONAL NOTES*
Dehumidifier FINALLY came and got it in the tent Saturday night (day 20). Humidity target numbers were not great this week as a result, but were in range 90% of the time since adding the dehumidifier.
Made a change to humidity and temperature settings. This week was temp range 70-79F, target temp 75%. Heat turns on at or below 70F, AC turns on at or below 79F. Both turn off at 75F. Target humidity was 65%, with the range being 60-70%. This was only for reporting purposes, I have been controlling humidity by following VPD ranges for my set temperature range. VPD target range is 0.9-1.3kPa. Past data has shown when VPD goes down it's because humidity goes up when the temperature goes down. My plan this week has been not letting the temperature go below 70F or above 79F in the room the grow tent is in and turning on the dehumidifier when VPD in the tent gets below the target range.
The environment around the grow tent sits around 70% RH, so raising the humidity is easy if needed, but usually it's not. I have an intake Fan to install so I may move the dehumidifier out of the tent and into this room, depending on how well I can get the tent conditions to match the external room. The dehumidifier has raised the temperature slightly in the tent, but not enough to be alarming, only 2 or 3 degrees max.
AC is in the external room and the tent is usually with 3 degrees of the room. Tent is currently venting out into this room, AC vents outside. We'll be changing the tent to venting outside in the coming days.
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.
