These were all under LED, Platinum panels 2 p300's. The paternal line was done all under HPS. Interesting to see the better response on the HID over the LED. Im curious to the spectrum claims on that panel. I just noticed that you had a hybrid setup the LED/MH and most MH guys pack HPS for the later life cycle, given your previous grows i figured that you would make the change.
If i ask too much or if i babble too much in here let me know. Tests like this, especially when i am not growing ATM, are huge. I get to see a few things that i just dont have the room to do. That is to test the different light deliveries as well as mediums to grow in.
All of them were bred in the 18/6 cycle and sometimes 20/4 when needed extra heat in the winter, used that to keep temps up over 55 at night as to not stop photosynthesis. Even though 50 is where it really likes to stall, i wanted to make sure that there wasnt any more than a 7 degree change in the day/night cycles.
