Birthday of the Mark 1 Mobile Photon Cannon AKA MPC1
4 x CXA3070 5000k at 1.4amps=235watts on a light mover in my 4x8 space. Walls will be going up in the next few days. Using the fan gives the light dual utility as it blows down large leaves exposing lower growth and foliage to light. I know that I have a rats' nest above my light and I will be taking the light down tomorrow to clean her up a bit. In a few days I will be building a my second cannon to add into the room and I will outfit these lights with some DIY reflectors. These lights are lite as hell from the plastic and pc heatsinks, but eventually I plan on re-mounting the whole thing on rigid plastic and aluminum sheeting so that I can ditch the fans and use an inline cooling system.
Total wattage of light in the 4x8=~675.2watts There is a lot more wattage being used by the room ~10w per Spectra, the light rail is 5.5w, and about 23w for the photon cannon fan, so a total of 68.5 extra watts. The room is running at 743.7 but I will run just over 1100w by the end of flowering. I will probably add my two bloom boosters and some small T-5 UVA bulbs near the end of flowering for at least 75 more watts but a majority of the grow will be less than 1000w. I may build a 730nm flowering initiator for the room as well. I would like to get the early yields that some people have been claiming on this forum.
Here she is in action, it's mesmerizing to watch.The light only bounces back and forth in the 5 feet at the center of the room.

I have had excellent results with my light mover in the past in the veg room, and I think that it will work out splendidly in the flowering cabinet. I think that this may be an opportunity to really stretch the limits of how close you run your lights, I think that if I can keep the lights fairly low but with enough spread to cover 3/4th of the room I will be able to push huge light intensity without burning out the chloroplasts. We'll see, maybe my plants will just freak out. The real trick is never having the lights go all the way into the corner of your room, but you have to keep the light high enough to cover over half of the room. Always move the stoppers inwards about 1.5 to 2 feet depending on your space. I will probably tighten up the move distance to about 3 feet once that second cannon is in place. I hope you guys are having an awesome day. I'm gonna go pass out as I've been working for far too long, my mother in law is visiting and the Mrs. is freaking out a little, so much cleaning, organizing and rearranging.
Sincerely,
IlovePlants
