CANNA_401 Today I'm starting a Purplematic CBD Mini Grow in my Homebox Q30.
I soaked the seed in water for 24 hours and now planted it in a coconut coir tablet.
The plan is to later transfer the plant into a tailored 10l Airpot, and the lighting temporarily consists of two Osram E27 LED bulbs until I find a suitable alternative.
To monitor the grow room, I'm using a hygrometer from Switchbot and for the circulation, a 140mm USB fan.
For the exhaust (once necessary), I'm using a 100mm inline fan from Vents (Quietline 100 7W).

CANNA_401 TAG7: Temperature: Ø 24.9 -- Humidity: Ø 51.8 -- VPD: Ø 1.54
TAG6: Temperature: Ø 24.1 -- Humidity: Ø 54.1 -- VPD: Ø 1.42
TAG5: Temperature: Ø 23.3 -- Humidity: Ø 48.9 -- VPD: Ø 1.49
Today I sprayed the pot with about 100ml of water (pH: 6.4), the plant seems to be doing great despite the low humidity.
TAG4: Temperature: Ø 24.1 -- Humidity: Ø 51.4 -- VPD: Ø 1.47
Unfortunately, the humidity levels are consistently quite low. Because my homemade 140mm fan didn't dissipate enough heat (sometimes 28 degrees), I connected the tent to my 80x80 tent to direct the air from both tents using the 150mm inline fan. (There is still enough negative pressure in the large tent).
TAG3: Temperature: Ø 24.5 -- Humidity: Ø 67.2 -- VPD: Ø 1.05
It's pretty difficult to keep the temperature below 25 degrees, and I hope the plant can handle so much light. Today, two 80mm USB fans will be installed for air circulation, and the plant will be placed in a 1L air pot; the soil was completely moistened beforehand (pH 6.3) and 1.5g of TNC Bactorr was mixed in.
TAG2: Temperature: Ø 23.5 -- Humidity: Ø 66.0 -- VPD: Ø 1.0
Today I measured the DLI and PPFD values in the tent and sprayed the plant with water six times. (pH: 6.6)
TAG1 - Today the little one has fully straightened up, and I installed a new 50w lamp (cheap lamp from Amazon with LM281B LEDs) that lights up the tent quite well.

CANNA_401 TAG14: Temperature: Ø 23.7 -- Humidity: Ø 56.9 -- VPD: Ø 1.18
The lower leaves are continuing to turn yellow, I'm not sure what the cause is.
TAG13: Temperature: Ø 24.3 -- Humidity: Ø 47.8 -- VPD: Ø 1.42
TAG12: Temperature: Ø 24.1 -- Humidity: Ø 53.7 -- VPD: Ø 1.12

TAG9: Temperature: Ø 24.0 -- Humidity: Ø 53.6 -- VPD: Ø 1.39
Today I watered the little one until I saw slight drainage. (pH 6.3)
TAG8: Temperature: Ø 25.1 -- Humidity: Ø 49.4 -- VPD: Ø 1.62
The climate is really hard to control in the small tent, especially the humidity is consistently quite low.
Like with my other Purplematics, the leaves are curling a bit.

I think I need to put the plant in a bigger pot because the soil in the current one dries out too quickly.
