Multi-Planar Scrogging
Sorry about the delay on updates, but I have been busy with various projects. I have thought of a name for my scrogging experimental technique that I have been working on and I have some pictures to show you. I have not seen anyone using this method before and if anyone has seen this elsewhere please let me know. I definitely would like recognition for this if it increases yield like i think it will and it turns out that this is an original idea that I have come up with. I call it "Multi-Planar Scrogging", and more specifically the "PENTASCROG" with "Penta" denoting that there are 5 planes being scrogged. There are 4 vertical screens attached to the borders of the horizontal screen. They form a five sided box or basket if you will. The reason that I thought of this is I was thinking about the way that I like to scrog by weaving the branches through the screen in order to keep the growth mostly horizontal (for even light coverage and maximum surface area).
One of the problems that I ran into with the Skyscrogger was that it shot up chutes that blocked out the light from the growth at the screen which caused it to produce fluffier medicine in the light-starved areas of the screen. From this experience, and seeing how the various RDWC scrogs of the same strain turned out, I decided that when weaving the screen it is best to cut off the chutes and avoid overcrowding. The plants with uncrowded branches running horizontally produced denser, easier to trim meds, and bigger yields.
In this thought process I realized that it would be advantageous to cut out the center chutes. I also noticed that the colas along the edges of the screens were uncrowded, and grew up vertically forming healthy dense buds. Then this got me thinking about how you are not supposed to be able to yield more than 2 pounds on a single 1000 watt light which optimally has a throw of a 4' X 4' area. The ratio then would be a limit of 2 pounds per 16 square feet, which reduces to 1 pound per 8 square feet. It seems like the 1 pound per 8 square feet limit is accurate and usually only achieved by a skillful grower with the proper strains who uses the
sea of green method. However I hypothesize that the limit of yield per 1000 watt lamp can be further maximized by increasing the surface area using my experimental Multi-Planar Scrogging / Pentascrog method.
This math is all for the 8' by 4' G13 scrog, and I have added a 1 foot tall border that runs around the perimeter. The 4' X 8' screen has a surface area of 32 square feet which would have a maximum yield of 4 pounds by conventional methods. Now add in the 1' tall border with a total surface area of (1' X 4') X 6 panels = 24 additional square feet of surface area. This could increase the yield by the same percentage that the surface area increased assuming that they are directly related. This would make the theoretical maximum yield go up by 24/32 = 75% to a theoretical maximum of 4 X 1.75 = 7 pounds.
Now the best yield that I have gotten with a single plant under 1 KW in a 4' X 4' screen so far is 1.6 pounds (this was a plant that had solely horizontal uncrowded growth), so I am going to use that ratio to calculate what I believe is my realistic maximum achievable yield for a single plant in the 4' X 8' G13 Pentascrog. 1.6 X 2 lights X 1.75 = 5.6 pounds realistically assuming that the relationship between surface area and yield is in fact direct.
Now for the coolest part- if this technique is used with a single plant in a 4' X 4' screen under 1 KW the theoretical yield actually increases by a higher percentage, it doubles! A 4' X 4' screen has a surface area of 16 square feet and with the 1' tall border on all four sides it increases by (1' X 4') X 4 panels = 16 square feet, an increase of 100%! This means the theoretical max for this surface area is 4 pounds, and a realistic maximum for a single light Pentascrog would be 2 X 1.6 = 3.2 pounds. Of course this will require either a longer veg time, a very stretchy, probably Sativa dominant strain, or perhaps both. :evilgrin0040::anim_09:
By the way I chose the border height of 1' because you have to be able to reach the center of the screen.
Personal note (Proof once again that it is good to share!): Through being baked on ISS, and explaining my rationalizations and calculations, I just now realized that it would be a great idea to add one more vertical screen2' x 4' screen that will bisect the 4' x 8' screen. This panel will be shared by the two lights so realistically I can only count it as an increase for one of the lights, but it is still an increase in total surface area for the single plant of 8 more square feet. This gives a new total surface area of 64 square feet and a theoretical max yield of 64 square feet X (1 pound/8 square feet) = 8 pounds. This this gives a realistic potential maximum yield of 64 square feet X (.8 pound/8 square feet) = a full 6.4 pounds. I can put this bisecting screen in there solely because there is a light on both sides and this will leave nothing in the shadow when the chutes run up the screen.
This means for the G13 is now officially going to be a HEXASCROG. I will attach the one remaining 2' vertical screen tomorrow after I wake up. I will not have to reach over this screen at all and the center chutes are just waiting to start running up the screen while the rest fills in. These are all theoretical numbers and they assume that the relationship is direct (linear) between surface area and yield, but one thing is for sure it will increase yield. You could even put taller screens on sides that are not ones that you have to reach over for any reason. Also I suspect this technique will work best for people using wide dispersion/ throw hoods such as the Magnum XXXL because light will reach higher on the sides and allow higher side screens. I will try the technique here under these hoods and possibly under the XXXL Magnums we use on the RDWC scrog.
I will post more pics soon once I attach the center vertical screen.
