Its my first grow ever and i would like to know if i am doing anything wrong, I am on a very low budget so i have very limited options for my plants, i am using a home made cardboard box with a cfl lamp over it.. i have no understanding for how to set up the vent sistem, where to make the holes, how to place the fans(planing to use pc fans), so a little of bit help would be great! Im planing to put the grow box in a big closet with sliding doors, so i want to know what options do i have considering i want the doors to be closed.. what do i need, to make shure that the plants are getting fresh air in and the heat to go out, what kind of setup would you recomend..Also can someone plese tell me what nutrients to use if i cant spend any money on fancy professional shit .. I heard about milk mixed with water, but am not shure if its good for indoor use so help! Thank you for any help!
