White Widow - Seedsman Seeds (Feminised)

Nothing noteworthy for plant development. Still working past the cotyledon on the first set of leaves.

As anticipated, the addition of a third tent has affected the micro climates of the other two tents. (I mention it here because this thread contains the posts regarding the addition of the third tent)

In the nursery its a positive change. Higher humidity, higher temp. Avg. 25 C @ 75%...

In the flower tent I'm seeing temperature spikes like I haven't seen before. Now up to 29 C. Even after taking 100 watts of supplemental lighting out of play and reducing rh to reduce exhaust filter resistance... No help. Redirecting fans to a few different configurations... At a bit of a loss. I don't really want to pull air directly from the basement side of the wall into the tent. Avg. Temp out there 18.6 C this time of year. 🤬 Lol

The veg tent runs a little cool at 22.5 or so...

I'm rearranging intakes and outputs to create a better flow through the room. I caved and opened the exposed passive vent on the flower tent. Its actually functioning as an exhaust vent, open, so I can turn the intake fan up. The flower tent is running at a slightly positive pressure now. I'm now the basement light nazi again...

Flower tent down to 28 C... Veg tent up to 23.1... Nursery unchanged... still pondering it all.

Also, wouldn't you want negative pressure to pull the hot air out faster through the exhaust and get the new, cooler air in to replace it? This is my current theory with my tent and it seems to be working better than when I pushed more cool air in.

Yeah... That would be ideal wouldn't it... Lol

Best I can do until the intake filter picks up some resistance and/or the carbon filter dries out and loses some resistance. Passive vents to relieve pressure is the best I can do at the moment.

I'm pulling about 300cfm through this 5' x 5'. The heat is just a summer thing... 😉 Gotta slog through it...
 
No plant duties tonight, I'm finally ahead of the mine field I set out for myself over the last few months.

The nursery is happy as usual.

The plants are all happy, catching up on neglected cleaning duties today.

Transplanting in 100 square foot grow room gets messy... Considering that of the 100 sq/ft or so I have to work with, the tents occupy almost half that space.

Cheers
