Everyone is buying really expensive equipment for 100-1000$ and dozens of nutrient boosters and stimulants etc. expecting better yields.
These people should realize that it is not about that, but that it is about grower´s skills.
When you reach yields about 700-750g per square meter with basic equipment and nutrients, than you can start experimenting with other stuff. Later on, you will probably find that all these things are useless if you are good grower.
For imagination there is an example how basic system could look like. Great effective low cost design
Nothing misterious about that.
You dont need LED panel for 1000$ to get good quality yield with effectivity over 1 GPW.
Nothing against LEDs, they are just still too expensive. And when i see setup that costs about 1000-2000$ with effectivity about 0,9-1,3GPW i am little bit laughing
