Ive got 6 beauties into week 6 of veg now under a t5 4'x8bulb lamp and we had to cut the power to the house today to re-wire over half of the pad. How long (maximum) can plants in veg be in darkness before serious damage occurs? They are all healthy
one (up to) 24hr block of darkness may shock them a little but if there are no other interruptions once you get them back on the cycle,,they should be fine :^)
