That is always the tricky thing is not knowing how a plant will grow, if I were in your situation I would remove the scrog net and LST/BUD tie as much as possible if you have the vertical height to spare then your horizontal growth is already going to max out, so in the interest of yeild I would try and get em to strech as much as possible because that is where you have the space. The plants are going to grow to the space that is given them. With photo plants you have the ability to control how big they get by how long you veg them(more or less) so at this point your plants have probably grown as Wide as they are going to, now try and maximze the vertical space you have.
Again this is just my thoughts based on the pictures you provided, I dont know what your lighting and temps are so that plays a big part in things as well. Can you raise and lower your lights?
Here's an overview of my equipment:
- 2.5' x 2' x 7' tent
- 400 cfm inline filter/fan combo
- Intake air comes through a screened port in the back that sits just above soil level.
- 300-380 actual watt LED panel with 5 watt chips.
- 4x 45 watt CFL's. I use them for viewing plants, and some pictures. Sometimes I'll use them to help warm up the tent. Maybe I'll use them in flower this time too?
- 7 gallon Smart Pots filled with a mix of Fox Farms Cocoloco (35%), Dr. Earth 808 (5%), and perlite (60%). Sounds crazy with so much perlite, but it's worked great before!
- Small oscillating tower fan placed near intake vent to help force fresh air around. Small fan pointed up near door to keep that air space from becoming stale. I'll probably need something for above the screen too, to blow on the flowers.
Here's how my tent runs:
Intake temps: 73-75 F day, 69-72 night.
Top of canopy: 75-81 F day, 69-72 night.
Humidity: 50-70%, usually right at 60%
I have no heat issues atm. I think my 400 cfm fan is overkill in my tent. When I sleep, I turn it down to minimum speed, which still keeps good temperature. I turn it to max while awake and it holds a very constant temperature.
I can raise and lower my lights easily enough. From where my panel currently hangs, I can raise it by almost another 2 ft before I hit the filter.
