Watering with lights on or off?

Should you water when your lights are on or when they are off? And why

IMO early when the light just turn on. Therefor they have water and nutrients more readily available during the whole light cycle.

Depends on the system, but for the majority with lights on if automated because they don't need as much with lights off.

Lights on, because I can't see what I'm doing in the dark

When they are dry and need watering.

Preferably lights on I'd say, helps seeing as another poster mentioned when you're stoned as fuck.

Water when the plants need to be watered.

Some methods of growing you have to water during both light and dark periods. When I was doing flood and drain there was no way the plants could go 12 hours during lights off in hydroton without flooding the table. So the plants were flooded on a timer every 3 hours for a total of 8 times a day/24 hours.

I use blumats with coco and those drip 24/7. When I have soil plants in the tent I water them when I have the time. Often that's right before lights off when I get up in the morning. The plants don't seem to care and that's all that matters.

Why would it matter?, In Hydro roots are permanently in water and has some of the best indoor crop methods like DWC or NFT.

Thanks everyone for your opionion...happy growing

I’m not the op, but I’m guessing because he’s doing hydro with spoilless medium

I water at lights on, specifically because during lights off, it's pretty cool in the grow areas. 56-64F. I keep my nutrient mix just above room temperature, so that when I water, it warms the root zone just as the plant's day is starting.

I grow in Sunshine #4 peat-based mix.

I run my lights at night so I can water/feed just as they turn on. This gives them time to vent and evaporate all night long and seems to cut the risk of any mold issues popping up. Also eliminates the coldest part of the day and keeps the gurls cozy.
