Getting the rust off

The non mainlined girls are starting to be a right pain to take care of. The wire ties from the LST make watering difficult, and they are keeping the humidity up. Also, the heat outside disappeared, so the house is running a bit cool. I would start to exhaust the air to the house, but my current carbon filter (from the last time I grew 15+ years ago) is failing, and for some reason I don't want to put on the new one until the next grow. The work to LST, trim the anemic undergrowth and difficulty water says enough that this rando LST is not something I'm going to repeat. I haven't made time to get a stable screen setup to attach to the pots, so that's also out. Of course, I also happened to snap one of the mainlined girl's stems. It was a 1/4 stem, so only 2 of the 8 growth tips are affected. I'll update later with a picture of her in her electrical tape, but it's been a few hours since the snap and the leaves are doing well. Her arms are just so thick and short, so don't have a lot of movement to try to pull them further apart from each other. I'm tempted to flip to flower tomorrow just to get this grow over with. The crop and attempt to de-chaos after the super crop is just a mess. I want to be working with 2 4-way LST plants, and 2 neat mainline plants to see how well they compare against each other. The only thing that's holding me back is I think the mainline plant should get a bit more veg time before the flip to flower. But, I will do at most one more week of veg. Wednesday. Considering the mainlined girl was snapped last weekend (and Monday I re-snapped the taped limb), I'm finishing this week of veg. I bought some metal conduit to brace the sides so they can't suck in around the canopy, but likely won't get a chance to put it in until this weekend. The plastic 1/2" PVC piping that others have used felt more bendy than I wanted. I took a few pictures to demonstrate that the girls are currently filling all the space they have with the tent closed.
