If they are T8s or T5s it is okay. LED or HID - turn the bright lights off. Spray undersides mainly and some on top of leaves. Also turn the fans off. Let them sit for 45 minutes or so then turn on the fans. Let the fans blow on them for an hour or so then turn the lights back on.I'm in veg right now. Most of them are a foot tall give or take, about a month old, then I have one bigger one that is about 2 and a half months old, also still vegging and yes I have I believe a 56 oz sprayer.
How critical is it to spray during lights off? Lights are only off while I'm at work. I started some spinosad Sunday evening, I will be shooting them again with it tomorrow. They were sprayed during lights on but I turned all fans off for about a half hour.
There didn't seem to be any negative effects on the plants as far as spraying with the lights on. Is the chance of scorching the plants spraying lights on the main worry or does it make the treatment less effective spraying during lights on?
A gallon sprayer is 128 oz I think. Just adjust your mix by 1/2. Soaps, essential oils, canola oil, etc are fine in veg. Neem oil is also very good when in Veg.
If you are in the USA you can get this stuff at grow stores, Home Depot, Lowes. and surprisingly Ace Hardware. My local Ace has a great selection of spinosad, insecticidal soaps, pyrethians.
