I just finished the best LED thread to the end and what a read! ( I posted there but it seems that the momentum has perhaps shifted to this thread now)

These Martian nights sound like the future to me. (I'm already a UFO conspiritor so i love the name! :P )

The idea of a 24/12 grow sounds like it is and should be possible for us in the near future with a few more clues desciphered. It looks as though we already know that the Far-red wavelength is essential to balance the Pr / Pfr ratio. I took note of Sal's recommendation about Mother's initial set up in the "Best LED" thread. He had taken note of the 126watts of Far-red illumination that you had in mind for your set up and said that you would likely need what he specified was about twice that amount of( i think it was 250watts or so he suggested) wattage to balance with the competeing Red (660nm). It was something to that effect, please don't crucify me if i'm wrong. (I tried to find exact quote)

Am I mistaken in thinking that a 89% Red to 21% Far-red would be good during the day and inversely perhaps 89% Far-red to 21% Red during the Martian night time on a 24/12 flowering schedule. I could be way off here but i'm just postulating a bit. We know that the absence of the light in the blue (<500nm) has to do with making the trigger to flower happen. It seems like all that really leaves us to play with is our Red/Far-red ratios during day and night.

Anyway i've set up a new room in a new house (starting from seedlings for that matter to avoid mite or bacterial contamination from transplanted clones) I have previously built my own array and modified some high flux LEDs to run a small grow box (veg was great/ flower not so hot) as a precursor to spending some money on a Procyon lamp, which i finally did purchase. I am adding some seedlings to my grow as they germinate and form tap roots. At the moment only 1 really took off, but i've planted what appeared to be another good candidate today so hopefully i'll have a few plants to work with. For the most part my seeds should consist primarily of sativa breed and Northernlight's derivatives thereof. Notoriously i have a nack for germinating females, hope my luck holds here.

Mother i hope you don't mind another grower hitching his trailer to your thread. I will be doing my first attempt at a Marian night grow with the plants that i am starting here as well, and it would be good to keep us all in the same place for ease of access to the information gleemed here. I'll be awhile getting there late as i need to establish a healthy mother plant first, but i promise to do the experiments.

One thing that i have been thinking about doing is purchasing another Procyon (I'm really impressed with the penetration levels the Cree LEDs produce) and modding and paralleling the two combined blue arrays and red arrays together. Knna will be please to hear that i agree with his statement that they are cranked up too much by default. Right now my 1 procyon lamp is sitting nearly 3 feet off the floor for my 1 little seedling. Its a waste and i could be turning it down and lowering the light instead. I am an electronics hobbiest and I enjoy modding and making things work better or more the way i intend them too. As well i would then gain the control i would need to establish a martian night with the procyon 100. Its too bad there are no Far-red Cree's or i would definately go that route, however i did find a good supplier of High powered Far-red Leds HERE. I'm getting on ordering them now. Could take awhile to arrive. I am supplementing my Procyon with a 40w CFL to help provide all the other spectrum during veggin 24hours ATM.
Sorry for the long post.

Mother let me know if you would prefer i start a separate thread.

Here are a few pics.




Thanks all. L8trs
hey dude, i don't know about mothers feelings if you post in this thread, but you should definitely start a grow log too. you can copy and paste the same stuff or just post your conclusions in mothers thread. i just think the grow log would be of the utmost benefit. that way there would be a start to finish, materials included, defacto guide...even if the method is still a work in progress.

just something to consider.
