4/8 - They are doing great. PPFD at 800. Debating if I want to do CO2 this grow, because I could easily get 1000 PPFD out of this light. That means adding a dehumidifier to keep a sealed environment, but don't think there's enough of a cost benefit. Might just add more far red at lights on and lights off to try and get a little more vegetative stretch before I switch over to 12/12. Clock is ticking. Mother-in-law shows up 6/15, and I'll want it chopped by then. 4/8 - on further calculation, I'm switching to flower today. Never switched this early before, but we'll see how it goes, eh? 4/9 - prepping for vacation. Bought new 10 gal Roughneck storage container, mixed new nute mix 2:1:2. EC 1.40 with 0.3 tap water. 11ml of pH down to get PH from 6.4 to 5.8. Ditching the auto fill. Too high risk for flooding without flare fittings. Don't trust cheap-ass quick connect push fittings. 4/10 - turned off "seedling vpd mode" which kept humidity artificially high. Turned on 2nd bank of LED lights, so system is pulling about 370W with lights on, still significantly dimmed down. Turned on light cooling circ fan, which is a sealed aluminum labyrinth tied to two 4"vents. Although, almost all the heat this lamp generates is from radiation, not thermal loss of the LEDs, so the heat sink is barely warm. Lights up to 16" over canopy to allow growth while on vacation. Ppfd at canopy 800. Room temp 81, humidity 73. Auto water time is 30 sec per pot.
