Hey
Jennifer28 thanks for stopping by and welcome to the forum. Here's a general overview of my process which I gathered from GWE website and tips from a lot of friendly people around here.
Canopy
I let my plants get to about 7 nodes and then I top them down to the 5th node and start training them in a way which is very similar to the guide @MRFURLEY provides as part of his "plant training" thread. This method combined with a trellis netting (called a "scrog") for support is what I did to create the canopy you see here.
I also defoliate (remove leaves) and "lollipop". These are terms you can search on the website as needed.
Lighting
I use LED "quantum boards" primarily that are about 240 actual watts, 3500k spectrum, LM301B diode. That's all technical speak that you could use in a Google search to find a similar product as needed. I made mine from individual parts purchased from ali baba.
I also use CMH/LEC fixtures. But I dont like them as much because they're hot (which requires more ventilation equipment and could destroy terpenes).
Nutrients
I am still on my first bag of Mega Crop and really happy with it. This all in one nutrient is sometimes combined with a carbohydrate during flowering stage but could grow beautiful buds on it's own.
Medium
I use a 70/30 coco perlite mix
Let me know if you have any specific questions I missed
