how are you obtaining over 2 grams per watt and how can i do it? your not doing a vertical grow are you? how close can your plants get without burning
I am doing nothing special. No advanced pruning or anything like that. I may top depending on the strain and I always "lollipop" my plants. Only the first 5 to 6 inches up the stalk though.
I use quality soil, lights, nutes, etc and I tend to them 3-4 hours a day. I am semi-retired (yeah you can say it, I am an old guy) so I have the time to do so.
Now I do use "passive" CO2. Meaning my flowering areas are in the same room as my furnace and hot water heater. Both of which use natural gas. CO2 is a natural by-product of burning natural gas. I have never taken any CO2 readings so I really dont know how much CO2 is being emitted in there.
Maybe that is my secret. I never really put much thought into it other than, "whatever CO2 is coming off the furnace and water heater can only be a good thing. Lets put the flowering room in there with them". That was 12 years ago.
Also, it is only a few strains that I get that type of yield from. Skunk #1, Afghani #1, and Chronic to name a couple. Mainly your heavy to pure indica strains.
There are plenty of other strains that I dont see that kind of yield from. Some of it is genetics and some of it is simply my method of growing and that strain just plain dont get along very well.
I wish I had some kind of magic wand answer for you but I dont. And no I am not doing a vertical grow. Straight soil with overhead lights.
Everyones set up and environmental aspects are different so that will effect how close you can get your light to your plants.
The way I have my 1000 watt set up, it is in a fixed position 5-1/2 feet above the floor of my flowering area. I do not raise or lower it ever. I just place the plants in and let them grow to the light. I use the following reflector:

The walls of my flowering area are not permanent walls. They are 4 feet tall sections of blueboard insulation that are covered with mylar and can easily be moved out of the way so I can get in and work with the plants. I velcro the 4 corners where the blueboard sections come together when not working with the plants to prevent light escaping from the "flowering area". The floor is painted white. The top is open except for the light fixtures. So you see, I have flowering "areas" inside a much bigger room. Works great for naturally controlling heat and for ventilation.
Sorry if I babbled on more than you ever wanted.... but you know how it is after taking a couple hits.
