watering questions

1)how often should i water marijuana plants
2)how much water should i give them each watering

For seedlings a damp top inch or two on the soil is all they need til they get bigger. Once they develop a good root system increase the watering until u get a little drainage from the bottom of the pot, not much, to ensure ur plants roots are absorbing the most food and water possible. Once u reach this point, u don't need to water again til u lift the pot and it feels 'empty'

should i use a spray bottle or just pour it on

depends on how close your lights are to your plant.. if its really close then dont foliar feed because then youll burn your leaves. what i did was took a small vitamin water bottle. heated the cap up and poked holes in the top like a small watering can. then i squeezed it and sprayed it around the bottom of the plant. seemed to work for me. sometimes i spray bottle sprays too wide and gets the leaves to puddle water.

im growing in a green house so im pretty sure the sun is far enough away for me to foliar feed
