Thank you so much! Also thank you for the interest in the rest of the process. I will definitely be sharing a full detailed process for everyone, every step is as important as the last! As for the medium we use a 70/30 coco perlite mix and the lights at my facility are 1000 watt hps aircooled with digital ballasts. But we see much better results with the 1000 watt gavitas at the other facility.
