Hey MP, do you mean spin your plants in place, or spin them around the fixed bulbs? If you meant in place, there are things called "Lazy Susans" i believe that allow you to rotate plants from a fixed spot. I have recently incorporated a couple of these to help spin my larger plants without lifting them too much in the tent that I have (for it is pretty taxing bending over to pick up and rotate 5 gal buckets with plants that were just watered etc..) I'll take some pics if you want me to....
I am running something similar for my set-up, but I have CMH's on each side of a HPS in the middle. I think your plants will enjoy the duel spectrum, I know mine do! The thing I have found interesting is that even though the HPS puts out more lumens, plants that are equa-distant from both lights will orient toward the CMH's....
Anyway, looking good as always, keep it up!
I had wanted to spin the plants in place, so all sides of the plants would be recieving light as it rotated. Lazy susams would work, but I was lookin for a motorized way of doing it so all sides get exactly the same amount of light throughout the lights on period.
I actually posted this idea a couple years back on grasscity forum, and just recently while reading through maximum yield I found a unit that did exactly as I had wanted to try back then. The site isn't exactly woking but they do show the typical high times mag advertisement with a couple hot whores hanging all over a unit that does what I intended though on a much smaller scale then I envisioned www.spinnerhydro.com
That's interesting that plants lean towards the cmh light in your setup.. Pretty much goes to show what they prefer.
I also missed a post of yours with questions a few days ago... With coco I keep the ph between 5.8-6. I'm currently running Rez's and H3ads modified lucus formula for coco which is really a minimulistic approach to feeding the plants in coco. The get what they need, and nothing more, which I found makes for a nice flushed out plants by the end if you follow the regimen exactly. You can find the regimen in a sticky in the reservour seeds vendor section.
