I just got the notice that my electricity will go down after week for couple of hours maybe 5-6-7 hours and the problem is that i will be in week 2 flower

Hello. Yes everyone is right. Here's my suggestion... Rent an electrical generator, at a tool rental place. I can rent one for a day, here in Canada, for around 50 to 80 bucks + fuel cost = around 100 bucks for a day. Plug in your lights, a fan to keep the air moving and your freezer or fridge so your food don't go bad. Easy.... Chuck.

Light some candles for them.

Don't panic, you're going to be absolutely fine! First, to ease your mind: a one-time extended dark period will not cause your plants to reveg. Reveg (re-vegetative growth) happens when photoperiod plants get more than 12 hours of light, disrupting their flowering hormones. Extra darkness won't trigger that, but it can occasionally cause some minor stress or, in worst-case scenarios with unstable genetics, hermie issues if it happens repeatedly. Since it's just a one-off 5 to 7-hour power cut, the best and easiest thing you can do is adjust your timer to match their schedule for that day. You can simply let the plants stay in the dark longer, or shift your light cycle ahead of time so the power outage falls exactly during their scheduled night period. Just make sure that once the power comes back on, you return them to a strict 12/12 routine. If you can't change the timer, just letting them sit through the extra dark hours for that single day is still much safer than having light leaks during their dark cycle. Keep your extraction fans in mind though, as a couple of hours without airflow can cause humidity to spike, so try to keep the tent closed to preserve the environment. Happy Growing Growmie🌱

Length of uninterrupted darkness per day is the key to focus on in regard to re-vege concerns. Ensure it gets 12 hours of uninterrupted darkness and it will not re-vege; gauranteed; no worries; that's how the biology works... The actual length of uninterrupted darkness is somewhat variable. 12 hours is safely above thath variability. 10 hours might flower some but not all, for example.

Better to have darkness during your day hours than light during your night hours...............which is the biggest cause of issues. Your plants will be fine with a few hours of darkness for just one day. If it happened every day for weeks..............then you might get issues, but a one-off.............no worries.

Stop worrying. Here is a secret: Cannabis loves darkness. Makes cannabis feel sexy. They need light, sure. But they love darkness. All long night plants love darkness.

Don't panic, you are completely fine! Your plants definitely won't reveg from this. Reveg only happens when photoperiod plants get too much light during their dark cycle, which disrupts their flowering hormones. Extending the dark period or having an unexpected blackout during the day will not trigger revegetation. Since it's only a single event lasting 5 to 7 hours, the absolute worst-case scenario is that the plants experience a tiny bit of minor stress, but it won't ruin your harvest or turn them into hermies in week 2 of flower. Just let the lights come back on whenever the power is restored and keep running your normal 12/12 schedule right after. If you want to minimize any stretch or humidity spikes while the extraction fans are off, you can leave the tent intake flap slightly open for passive airflow, provided no external light leaks into the room. Just let nature do its thing and your girls will bounce right back. Happy Growing Growmie🌱
