I reset the 2x4, clean as new. Trimmed the Do Si Dos. (215g one plant) Moved these girls into the 2x4. They finally got the humidity! (35% to 62%). Slow increase in PPFD from 60 to 120. Rehydrating the soil in Earth box, will top dress next week. It’s been 15F at night and arid, anytime I open the tent RH drops to 40%. Had to disconnect in intake fan and seal the tent to retain heat and humidity. *set heater, humidifier, and target the inline exhaust to cycle out air a couple of times per min. I like how things are going so far.
