ok how long are your lights on for? there are two main stages of growth, vegetative growth, which is where you plant grows at a decent rate. and then there is budding, which is where your plants start producing the good stuff. you want to start the budding cycle at about a month at the earliest.
yah man like fuzzy said though, study study study. i had read for a year on growing before i actually started. now you don't have to get that extreme but you have to know the basic need of you plants and the different problems that can occur.
ok c you want to keep you plants under 18 on 6 off for atleast a month. trust me your plants would have been soo much bigger if you would have done it that way. then you put them under 12\12 for 8-12 weeks depending on the strain of the plant.
or you can keep them the way you growing them now and be lucky to get 10grams of dry smoke off of all of the plants put together. see the way i grow mine i get about 4 oz per plant which isnt great but its better than nothing.
well the little hairs should be about 75%amber all over the plant. amber meaning a redish brown color. then you cut and let dry but you should look that up as well. it can be a very long and difficult process as well
