Hey Dog, looks like your plants are coming along better than mine, but you're treating yours way nicer.

Mine are finally starting to flower once again. The timing is currently at:
10 hours daylight
3 hours Martian night
10 hours SID
1 hour Martian night

which would put the time factor for the light spectrum I'm using right around 2.0. Why 2.0? Because I'm replacing 2 hours of total darkness with 4 hours of "night light". The plants need a full four hours under the night spectrum I'm using in order to make up for only 2 hours of total darkness, so the "time clock" of the plants is running only half as fast when the Martian lights are on. But on the flip side, I'm getting four hours of night photosynthesis in trade for two hours of day photosynthesis. I'd definitely get more if my Red was not 660 nm, the peak for Pr sensitivity.

The Martian night lights I'm using are:
52 watts of 660 nm Red (672 individual 5mm LEDs, which are not terribly efficient)
50 watts of Red Incandescent light

I also swapped the two 26 watt 55/6500k CFLs back for two 42w 2700k ones because the heat is less of a factor now.

Hopefully that helps provide at least some information that will help us figure out the time factor of each of the spectrums.

The plants have been quite stretchy recently, which I expected because of the high levels of both Red and Far Red during early flowering. Sal has warned that Far Red during early flowering promotes stem elongation whereas Red inhibits it, and tests by Dogznova have also confirmed this.

It broke my heart to do it, but I had to top about 4-5 inches off the newer HDF plant because it was already getting too tall for the cabinet, and it's less than a week in actual flowering conditions. Hopefully the stretch slows down so I don't have to do the same thing to the Vanilla Moon. We'll see!

I know I could just alter the spectrum and schedule to prevent it, but my goal is more to learn what happens than to make anything specific happen. At some point, when I've gotten what I need to out of these plants, I'll try a real crop with a real, adapting, Martian spectrum.

I'll also have pictures soon. I'm not lazy, I'm very busy.

First attempt at a 24-hour "Martian Method" In order to keep track of events, at the request of some online friends, and in order to share the love with the rest of the cannabis community, I'm starting my first grow log using the Martian Method, which I learned about from a very helpful Salmayo, here: http://www..com/vbulletin/showthread.php?t=30203&highlight=Martian and it has also been discussed in another thread on this board, starting at post 1438: http://boards.cannabis.com/indoor-lighting/150174-perfect-led-grow-light-58.html Rating: 5
