If its autoflower it will be fine.

Ive had autos in the dark for a few days before, they did stretch quite a bit though, but they we're only 14 days or so old at that point..

A Photoperiod on the other hand might switch to flower and may even herm depending on how long it's in the dark.

I have zero experience with photos in that respect though so I could be very mistaken.

Hopefully you'll be sweet bro, fingers crossed for you 



We had a power cut a few weeks ago, it only lasted a few hours but I tied a torch above my plant so it was shining down on her, I dont know if it did any good or not but I thought it would be better than sitting there in the dark.lol

Are you ok for temp and things like that.

If you can't say it with flowers Then don't say anything

Cool beans or warmer ones now 😆


Just for reference, I went as long as 5 days before without power. The plants were photos in flower so no issue with the extra dark. Harvest went fine, no hermies to be seen.
