how many ml of water should a plant get in early veg? everyday

i was also wondering if i could add some piss to the water to help the leaf growth, but i'm not sure on the ratios
i'm growing with a cool day light cfl

There's a lot of variables there? Pot size, medium,what you consider early vedge, strain etc.
Water them till you see some run off.
Yes on the piss too. This seems to be a tried and true organic method. But like I mentioned to someone else don't go take a leak In your hydro reservoir or anything. I only use piss outside in raised beds though
Dilute it. You can find the right ratios inn one of the threads on RIU. Peace

When my plants are still small under 6th set of leafs, i only water about 6 to 8 oz every other day slowly increasing every few waterings. By flower in 5g pots i water about half a gallon per plant every 2 to 3 days.
