The other day i went out and bought some worm castings at homedepot. The only thing is that they come in soda bottles and in a liquid form. The wuestion i had is whens the best time to use this? Should i use it when there about 4 weeks old right through vegation? Also do i just use the castings as if i was waterin them. Somones advice that is experienced with these kinds of castings would be greatly appreciated.

It sounds like you are talking about a tea, what are the nute nevels N.P.K? Start using nutes at like 4 or 5 nodes. you are probably going to be mixing a few tablespoons of that castings tea with a gallon of water, the bottle probably has similar directions labeled on it

alright cool...... thanks for the info because i would of just water it srait with those castings. Does anybody else have any suggestions for me?

I think that stuff works really good for foliar feeding (spray on). It came in a spray bottle right? I used the hole bottle in like 4 days all over my garden.
