Hi. With 2 26 watt CFL's that should be adequate. I only run two 12 volt PC fans with my 400 CMH/HPS setup but they are on monitors that spin up as the heat in the cab does. I would run at the minimum 4 26 watters in Daylight spectrum for veg and then swap out for 4 26 watters in 2700 warm for flowering.hey guys!
i have decided to run my first 12/12 from seed grow, and have it well underway.
i have 3-3 week old plants and 25~ beans planted w/ 4 peaking thru the ground. all bag seed. this is being done under CFL (52w at the time, will add more as they mature)....
one of my questions old skool has already covered, and my other one is ventilation. 2.5 sq ft shouldnt require more than maybe two PC fans...should it?
and im thinking of transplanting into empty butter containers when theyre ready, short and wide...anyone ever try this?
^ Don't worry, the only spectrum you will find in the 42w variety of spiral bulbs is the flowering spectrum. I think they are 2700k. I sure wish I could find some 6500k ones!
well for now through the next few days, they are under 5300 spectrum...i have added another bulb, now i have 3 26w. all my beans came up, but they are stretching, especially the ones that popped up before i added the new bulb, but i was wondering...does 12/12 for seedlings make them stretch?
sooo how tall will the plants be at their best if i 12/12 from seed?When starting the plants as seedlings you need to get them as close to as much blue light as possible to avoid any early stretch. I find this is extremely important in the first 48 hours. If using CFL's you can have seedlings almost touching the bulbs without any heat burn/stress issues whatsoever.
12/12 from seed. Small cab, so I couldn't really go up with it. Only one other direction to go....
