Wow Jon you got a lot going on! First I gotta say that your scrog-to-be lady is a gorgeous plant. Beautiful structure.
As for your experiment I say run it but only if you have a way to feed that much plant all the way through to the end. The more foliage the more food needed.
A 7 gallon pot won't be enough in my opinion unless you can feed it.
If you want an example of success I can give you this.... I built a 2200 gallon pot outside in my yard with excellent orientation for sun coverage. I filled it with my own LOS and planted a hybrid I made of a very chunky stinky colorful Rose Kush Indica crossed with a very branchy Cinderella 99 male that was of perfect Christmas tree structure, very similar to the Roses perfect Christmas tree structure but Rosie was more of a fat bottomed girl.
I topped the plant above node 4 and removed node 1, leaving 6 branches. I then scrogged her out with the bottom of 2 nets at 6.5 ft off the ground and net #2 at 7.5 feet above the ground. The final plant was 9 feet wide by 9 feet wide and 9 feet tall. You could walk underneath with only 6 boughs to look put for. So it was a 9 x 9 canopy but only 18 inches thick. A scroglipop.
At the outer edges I let branches grow around the 8 x 8 scrog net. I ended up with 29 tops above the nets and everything below lollipopped out.
I had about 10 pounds of foliage stripped that my worm farm ate over the winter. The final tally was 3 pounds 5 grams of only grade A bud. All lesser bud was removed as it got lost under the canopy. Zero larf.
I tell you all this so you know what was up top because underneath the soil the roots filled the entire planter. The trunk was as big as one of your legs is around in the picture, no BS.
So it took 2200 gallons of high grade soil fully mineralized as per Rev's recipe to grow a 3lb scrog with water only. Could I have done it in a smaller pot? likely but you now get the idea of what is required to go bigger.
I highly endorse that you try your experiment but the only way I can see getting a plant that big in a pot that small is with synthetics or tons of teas so be ready for that and pay it forwards to the pot. Don't let it become deficient or you won't be able to catch up and you will lose all your leaves by the time stretch is over.
It will need a liquid feeding every watering, whether organic or synthetic.
As for the discussion on UV and IR, I actually just bought a UV/IR bar and did a fair bit of research prior to buying it. Oddly enough there isn't a lot of info out there unless you get into very scientific stuff but I perservered and this was my conclusions...
As Mel said, UV is what gives you sunburn and trichomes are the plants sunscreen.
Thats pretty straight foreward stuff but you can easily give the plant too much UV and sunburn it before it has enough trichomes to sunscreen itself so it works best to use it at the high noon part of your light cycle and only once frost has naturally started or else there is no sunscreen.
Start it out at 15 minutes and as frost thickens, slowly increase it in both directions from noon until right before harvest you are using the UV for maximum 2 hours. Just like starting on your tan in the spring to be a bronze god by late summer. You can't just run out into 100 degrees for 8 hours in a speedo without detriment, you need to start out slowly.
UV also breaks things down and more will degrade your trichomes, then burn your plant. You can only expose a plant to a certain amount over its entire life before damage outweighs profit.
IR is more interesting. My take was that its more of an indica thing. At least thats where I see its biggest benefit, but I haven't tried it, my knowledge is purely theory and could be totally wrong.
When a plant is exposed to IR it doesn't get any photosynthetic value from it but it still feels its warmth, much like sitting in the shade on a hot day.
It actually invokes what is termed as a "shade response" from the plant, so the plant, thinking its in the shade, grows taller searching for the light it can sense and feel is there, but not directly to power photosynthesis.
It makes plants taller thus increasing mass that will eventually hold trichomes. More plant equals more trichome space. Then once its big you switch to UV and build the trichomes. It also invokes lankiness.
So I went with a bar that has both but can be independantly toggled on or off.
OK break time, my thumb is sore
Oh and yes, if you dust your entire rootball in myco at uppotting it will do better than not. I have done many side-by-sides with clones. It is better every time in organics regardless of strain. Myco is expensive because it works.
delivery cost me about 1000 dollars worth of cannabis seedlings and they comped me a few bucks. CL
you man. You better take me up on something. Lmao!
