as there are a lot of long term growers in this forum i think it would be helpful for us to put down our milestones in cannabis cultivation. by this i mean changes you have made that you would never turn back from, like using pearlite for example or switching from sodium to hps also it would be good if you could explain the difference it made to your yield/plant health/flavour. then some other can try you tuned in techniques. cheers all bigwits
