I'm just finishing off my first grow and while it's been overall pretty successful I don't feel as though I've utilised my grow space to the max so I want to draw on the community's exp to help with my next grow. My grow space is 1 meter square tent 1.8 tall under 400w mh/HPS light. I'm using a wilma 4 pot system with a mix of coco and clay pebbles. I've had problem with space more than anything, the plants grow in to each other and I end up with dense growth not getting enough light and air particularly towards the bottom. How would you overcome this. Pruning? Less veg time? Fewer plants? Stronger light? How can I maximise the space I'm growing in without causing problems?
