Two self-induced tragedies when it comes to indoor gardening.
#1. Over-watering
#2. over-feeding

Also remember that when you cut your light back and begin flowering your plants will almost double in height before they are done. If you have 6 feet of height space you might want to induce flowering at around 3 feet. If they grow too big and approach unsafe heights due to light and heat you can take a fine string/twine and bend them down by tacking the other end of your string to the wall with a thumb-tack. This will also allow light to get down to areas where it might normally not, which in turn produces nice bottom growth buds. Remember !!! Dont over-water Dont over-feed Good DRAINAGE is Good CIRCULATION is important.

One last piece of advice(although it wasnt asked for) Do NOT show your garden off to people. Including friends. I know its hard but it isnt as hard as doing time, losing job, losing house, losing kids, losing freedom, losing your bank account(mostly due to lawyer fees) Be safe. Have fun. Enjoy your harvest.
