Quality and purity are words I like to hear, friend.
This can be made using the dry sift technique I shared on this forum. It's in the hashish sub, here:
As I already replied via PM, you are more than welcome to pick my brain if you'd like.
I have been through the progression from 2, 4, 6, etc.. up to 16+ lights and everything in between and everything involved. People completely underestimate how much these 1kw bulbs can heat up when you start to add a bunch of them and don't have enough air moving through the room. If you are cooling your hoods that is one thing.. but a lot of people do not, and it makes me sick to my stomach when I see it.
Fried babies = no bueno. The cooler the temps on the surface the closer you can get your lights. The closer you can get your lights the better your product is going to end up. Bud density is basically directly related to light intensity. You can make fluffy strains.. not fluffy.. if you do it right.
If you run too much light and not enough oxygen you will starve your plants. You won't notice it by eye unless you've seen rooms done otherwise.
They will metabolize as much as they can given the oxygen and the light. Not enough of one or the other and you're just spinning your wheels.
Need to balance it out, have an equal pressure in your rooms, i.e. no negative pressure, or positive so it won't smell.. etc.
Lots of people don't figure it out for quite a while. Skip all that and do it right the first damn time.
