When growing in smaller areas like tents, its a good choice to crop or train your plant with LST to grow its maximum in the small space. Also if you want to max the yield getting more buds instead of a main branch.
I’m going to explain a easy way to do this now you want to wait at least till they are 6″ – 8″ in height is when I usually crop them. Your going to pinch off the grow tip just the top leaves that are growing out. In a few days it will regenerate and two new shoots will emerge. Do this again after they grow out some, soon you will have a branched out plant.
Once you have all the branches grown out you can train it to fill up and net by attaching the net (Trellis) https://www.hydrofarm.com/p/BCPSH16 https://www.hydrofarm.com/p/HGN15 https://www.hydrofarm.com/p/LHN010 to your tent poles a easy way is to use plastic zip ties. Once you have the net in place carefully push the branches through the holes in the net to fill up all the space. This will allow maximum light to reach all the buds on your branched out plants
You can also use garden ties https://www.hydrofarm.com/p/HGST to train your branches to spread out the way you’d like simply secure the wire around the main branch twist it around and up the branch and shape it the way you want it to go. If you need the branch to be pushed down use fish line and fishing weights and attach that to the branches to weight them down be careful to not break the branches although Cannabis stems are fairly strong, they may break if too much pressure is applied. I also sometimes use plastic zip ties to support the branches and spread them out so all are receiving a good amount of light.
