Static drug labs.
Currently, in each static lab there are 2 tables. Once for cooking Crack, Cocaine, Heroin and Meth, and the other for Seeds and Marijuana.
The problem
As it stands, you can cook 20 Marijuna and ~10 Cocaine per hour. If we go off the rough prices of drugs as seen below, that works out at around $6.000 per hour for the cocaine and $9.000 per hour for the Marijuana. So in the best case scenario it's $15.000 per hour, Taking away the cost of materials for the cocaine ($2.000) It works out at $13,000 roughly per hour. Which on paper sounds pretty decent, However the risk involved in this is so much higher than a lab at home, providing you cool the home setup adequately. You run the risk of SD/PD raiding the labs as well as rival gangs attempting to attack you. Not to mention you need a lot of people assisting you to be safe, so when you split the money it's by far not worth it.
My suggestion
I’m not looking for the labs to return to how they used to be, But my suggestion is more tables to be added. Maybe 2 of each, which would make the hourly rate roughly $26.000. I personally feel that this is enough to make holding a lab worth it for a gang, and with the ongoing need of drugs to maintain turfs I feel its needed also.
