answered grow question 4y ago
18/6 or 20/4 there is no need to do 12/12 and will only hurt your yield. Hole this helps good luck

Time lapse under HID lighting
How do people do time lapse with hid lighting? Do I need to set timers to turn off hid, turn on fluorescent and then take the picture? Is there a filter I could buy that eliminates the horizontal scanning lines?

HPS 400w Vs MarsHydro TSW2000 cost
Alguém me sabe dizer o quanto menos uma luz LED gasta comparado a uma HPS ? Por exemplo, estou usando uma HPS 400w, e subiu 40€ na conta de eletricidade, se usar uma MarsHydro TSW2000, iria fazer grande diferença ? Obrigado

Does anyone know what random 2 hour power cuts would do to autoflowers? Sometimes 2/3 times a day. I am supplementing with battery powered lights but I sometimes forget... They are on a 24 hour light cycle
