Critical+ will be a good choice to run in a vert scrog. In my experience, The Doctor, not so much. I planted to 10 packs of The Doctor, and every plant was trash. Slow growing, no stretch, just a horrible variety in my opinion.
Hybrid type plants worl best for a vert scrog. Full on "sativa's may present a challenge, because of the stretch. But that can be controlled, just a lot more work. When I ran a vert scrog, I had two levels of plants. One level at floor level, and another about 5' off the floor. Built a shelf for the plants to sit on for the upper level of plants.
I had bare bulbs hanging. A 600 up top and a 400 below it. I lined the walls with the green plastic/gray plastic netting that comes on a roll at the big box stores. Used that netting to pull branches back and secure to.
For my "door"/entrance in the room, I made a wall on hinges. Lined that wall with netting. Plant on the floor was on a homemade dolly with wheels on the bottom. So when opened the door/wall, the plant and all moved with it.
My best piece of advice I can give you, is pay attention working around bare hanging bulbs that are on. Cause you touch one with your bare skin, you're gonna know it. And have a physical reminder for awhile.
Photosynthetically active radiation, often abbreviated PAR, designates the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of photosynthesis.
