So far your good man. With dirt becareful about over watering. Over watering can cause your plants roots to suffocate. Your plant breathes thru it's roots too & it will cause the plant to seems sad. Avoid using any nutes since miracle grow dirt comes loaded with nutes in it. For about a month maybe a bit longer keep it all water.
As for the lighting, if your space is as bright as it is outside then your a lucky guy & your plant should grow healthy & pretty speedy. Considering there is no bulb in the world as bright as the sun.
Try & place a small fan inside your space with your plants. You want a nice breeze hiting your plant all the time. The plant sweats & the cool breeze helps it dry off all those chemicals. The light breeze also bruises the plants stem making it heal & grow thicker to become imune to the "wind" be careful to not make it a constant rough air on the plant. It's gota be light Enoch to cause a breeze & heavy enough to cause a bit of swaying. A soothing sway. The plant has to breathe so the fan is a must.
Water every week. Or lift your bucket daily. Get used to it's weight. Notice & grow a feelng as to how heavy the bucket is just after you've watered your plant & compare it to when your dirt goes dry. You should be able to tell the difference in a light dry pot to a heavy just watered pot. Be cautious of over watering dude. Sorry but I can't stress it enough. Personally I let my plants go dry for a while. The dry dirt makes the roots go thirsty & they grow out in search for water left over in the dirt. & your plant will always let you know when she's thirsty.
As for pruning never cut more then a 1/4 of your plants mass off at 1time. I personally prune right before I water & my lights go off so they can heal while they rest. Always use very clean sterile utensils too.
So your good so far man. Love your plants & just be cautious about everything. & all your fellow growers are always here for advise or feed back man.
