I had a power outage for about 4 hours in the middle of my light cycle. Will this cause any harm? Basically my lights come on at 2pm. Power went out from 830pm -1am. Then the lights were on until 8am.
It shouldn’t hurt it long as it is not a recurring thing. Think of it like a cloudy, stormy day, natural plants not getting much light for a few hours, and they turn out fine…
No harm! I had a major storm my first grow, like less than a month before harvest in full on flower bud cycle. Was without power for close to 28 hours and they lived. Just keep them back on their normal cycle.
Recheck all your timers, they may be off times now
