about 4 weeks in

my plants are about 10-11 inches now, and they are still under an mh light. i have never heard of lsting before, is it too late? they are fairly bushy already, and are beginning to smell good. when should I start flowering? these same plants started outside for about 3 weeks, and i only yesterday put them under the lamp, outside they were getting 13-14 hours of light, now that I have transferred them inside, and to a new light source, could there be problems? and how much light should they be getting at their present height(11 inches) Any help here would be great, I cant wait to get my own buds.

You can start LSTing now, just be gentle and make sure you don't break the stem.

Your plants will double to triple in height during flowering so you may want to start now.

You need 50w HID light per sq ft minimum , so it depends on the size of your growing space, LST will help maximize the usage of the area.

your going to have issues with mildew and or spider mites. start a fungi regiment and stick with it. neem comes to mind.

fungi regiment? please explain. and to lst, just tie the stem at a 90 degree angle right?

Yep, just bend it over gently and use some twine or string to keep it in place.
