Very impressive looking setup and TREES, not messin around in this thread!!!
I've been thinking about this unique situation with such tall tree's going in and the light coverage of 4 single lights per tree. This is all just from my OCD of trying to make things more efficient for what is put out. I could be way off base on this one but I'm going to throw it out anyway.
The main problem I see with this setup is light distribution to the 'whole' tree, or at least a decent amount more than it's seeing... I believe double stacking the lights would benefit this grow greatly and increase yeild.
Now, I am basing this on the info from earlier in the thread... a 10 plant, 15 light setup and assuming all 15 lights are 1000w. Is this similar to your current light/plant layout?
X= plant
0= 1000w light
0X0X0
X0X0X
0X0X0X0
_0_0_0
-6 plants get 4000w each
-4 plants get 3000w each
*Notice 4 plants only receive 3000w
----------------------------
Now in this setup I am going to assume each extra light (double stack-2000w) will increase plant growth/yeild by 15%, just gonna call it a .15 plant gain for tonight since it's late. I feel that I'm being conservative on this number because if you doubled stacked all 4 corners of the plant you'd only see a 60% gain and not double in my figures. But with such large trees going in this system that need even more side light distribution than normal to really get these babies to explode and utilize this system, who knows what the limits are on these monsters, it could get exponential growth rate by double stacking....
X= plant
0= 1000w light
#= double stacked 1000w's
0X0X0X0
X#X#X#X0
0X0X0X0
-2 plants get 6000w each
-1 plant gets 5000w each
-7 plants get 4000w each
*Notice the least amount of light any plant will see is 4000w.
So each double stacked light (2,000w) will add 15% to the growth of the plant over a single stack light.
-2 plants have 2 double stacked lights (6000w total each); each plant receive's a 30% gain in yeild for a total of 60% from 2 plants.... 2.6 plants instead of 2 from single light (4000w)
-1 plant has 1 double stack next to it (5000w total) for a 15% gain in yeild.... 1.15 plants instead of 1 from 4,000w
Here's where it gets interesting because of your single setup having 6 plants with lights on 4 sides and 4 plants with lights on 3 sides. The double stack diagram has 7 plants that are lighted from 3 sides but 1 of the sides is double stacked (4,000w each on 7 plants).
-7 plants have light from 3 sides but 1 side is double stacked (total of 4000w each)... But the original single light setup has 6 plants with 4,000w around them, I'm going to call this a wash and not include the 15% from the 1 extra 4,000w plant that is double stacked since they aren't getting hit from 4 sides like the single light setup...NO gain (make up your own mind on this part, I'm trying to be very conservative.)
¤2nd part of above- In the single light setup the last 4 plants are lighted on only 3 sides (3000w). This gives the double stack 7 plants that have 1,000w more each... (7x.15 = 1.05 plant for FREE).
Total = 1.8 FREE Tree gain!!
Take what you will from this as I haven't grown an MPB setup and just thinking outside of the box here which this system is completely about... In a way. At first this system didn't make sense from previous grow methods I'd read, after DD and Heath were kind enough to explain the system and why it does what it does, it now makes complete sense!
Way to hit it hard out the gate, very cool!
Alright, back to the pro's... :D
