I grow indoor and veg for about 5-6 weeks. First I put clones in hydro system to get a root base, works very good. Once a root base is built (usually about 6-9 days) I put them in dirt. This is when I start to count my veg period. I tie my plants back to train them instead of topping as they grow. This keeps them short and bushy with fat, dense buds that don't have huge stems that weigh a lot. I veg under a T-5 light that is kept about 3 inches above tops of plants for 5-6 weeks with a 18 on 6 off schedule. About two weeks before they are to go to flower room (12/12 light) I start to flush. I like to flush the girls twice before I start flowering. The day they go to flower room I add special bloom neuts (organic) to soil water and let them flower. You have to make sure your room has no light getting in. Also, do your plant maintenance when light is on. Do not go in room when light is off, just better that way.
One last thing. Put up a bulletin board with your plants listed. I use mailing labels and write down everything I do to each plant and stick them under the coordinating plant strain. This will help you so much. You will be able to see when you added neuts, when you watered, when you tie back or topped, when you did this, when you did that. It is a wonderful mechanism and when you are done you can put all the info into your computer and you will have a step by step guide on how to take care of your plants for future use.
Good luck my friend. I hope this helps. If you have any other questions please PM me and I will be happy to help.
