I have a mix of hlg and cobs..now.
I put higher numbered crops down too training the plants to fill the space.
Pinching out, bending and topping.
That being said average about 2-3oz each from 8 plants.
I’ve had amazing numbers from plants if you train them.
I’m short on head space so never grow tall sativas .
Best results 9z dry on 1 cheese plant think it was gh cheese under 300 watt cobs with a few other strains..
All hydro.
