Sounds like you will be just fine! maybe hand water them once a day.I am using an ebb and flood system with 4 feedings per day with individual pots. The pots don't completely drain therefore some of the roots sit in solution but that's normal for this setup.
No clue, I remember one time we had a bad snow/ice storm and it was out almost a week. I was DWC and we had no heat, so I had other problems that stunted them. The lack of light wasnt too big of an issue, although they will have some shock when the lights come back on, maybe raise the light up a bit the first 12 on.Thanks for the input. I'll chill till the power gets restored. How many day in the dark are ok?
