Damn man, a week, ya, that will bring them to show sex. If all of them are going to start to flower now, you wont get to much of a yield. As for the smaller ones, they wont show sex for awhile. You can start off at 12/12, some people do, and as soon as its mature enough it starts to flower, but ideally you want to vegg for 3-4 weeks before you start to flower.
Poweroutages at this time of the year? Where do you live? If you live near the great lakes, then yeah, the snow effect lakes will cause power outages. And unless you have a backup generator there is really nothing you can do. That really sucks you have to deal with that.
I live in New England, I get alot of Noreasters in the winter, and lake effect snow added to it, so accassionaly there are power outages, but I am not too worried.
You actually gave me a great idea. I could build a LED system, and have it battery powered for emergency power outages. LED's will work great for Veg, and it would be great to have for emergencys like that. Maybe you should look into getting a LED system large enough to cover the lighting for outages, and just keep some back up battiers. But I am sure a big enough LED system would take a few battiers. But hey, its better than having no light during a outage.
Keep the grow up! Ill be watching. Puff...Puff...Passes it to you
and the over wather/ under water can be tricky, sometimes a plant looks underwatered but was really overwatered. How much have they been watered. Best bet, is to wait until the soil is dry. Marajuana plant don't like to in constant moist soil, they like for it to dry up, so there roots go searching for more food/water. So as soon as you see the soil is dry, you can water it. If its still moist, leave it be, and let it use that water up.
