I use

canna coco soil and clay pebbles
15ltr pots
600w metal halide in veg and 600w HPS in flower
1 light for every three plants

I grow my plants to 9 and a half inch and then tip then, then let them grow to 14ince and flower. Total veging time normally around 4 weeks and 8 in flower!

I usually have grate results and have been doing this for a number of years, I just don't want to be missing out on better strains because I am used to blue cheese.

Let me know if you think I can make any improvements?
