Plants are looking great Esme
To bend the plants down I use some string and some safety string
I was wondering how to attach branches to those pots for LST, now I know how, thanks, great trick
Cant wait to see that full of flowers Dude I used those for CMH and it was nice. Check out this from Migro:

The cheapass umbrella reflector mops the floor with the other ones (IF i remember correctly)
Anyway I'm pretty sure thats just a testament to the benefits of vertical bulb usage, not really the reflector.
But tbh if I had 4 600s going in normal greenhouse reflectors I would be way too lazy to change them out. it sounds like it's not worth the cost for the gains once you already have 4 lights overlapping.
One side being 1.75m gives you a small advantage already. Now you use 685 w/m² instead of 600. Maybe if the room was truly 2x2 or slightly bigger parabolic reflectors will be a more significant upgrade. Just my 2 cents...maybe I'm completely wrong haha
