Well this is my first grow. I'm running sensi seeds super skunk, vision seeds northern lights and Humboldt seeds green crack. All responses and or advice are welcome as long as we keep it civil ppl.
I'm using a 400 watt mh bulb on a dimmable ballast that I'm running at 75% right now. I have a 172 cfm hurricane fan with a carbon filter to extract heat and later on smell. I will be switching to a 400 watt hps bulb for flowering. My soil is promix hp with some dolomite lime added to keep my ph levels straight. Been using BioBizz nutrients and I highly recommend them!
Some things to try are lolipopping and super croping your plants and topping. If you want multiple branches all fighting for the top you can super crop which is pinching a little below the top node and bending it over or topping where you chop the top off and let the side branches fight for the top.
