I think so, reg air is ~400ppm co2, you won’t run co2 after lightsoff. Probably room size matters, but if considerably larger than tent, should be ok.
You will need a meter, you can check room with it.

Yeah is a medium sized bedroom i think it will be 10/15m2. I will try to grab a CO2 controller as soon as I can and having a tank plugged in. How much CO2 money on avarage go away for you?

Can’t remember exactly, and on road atm, but a reg size welding cylinder is 50lbs, $38 for the co2....

Yepp, that would work good. The surface structure does'nt matter much as long as its a metallic surface.
A hammered sheet or a stucco reflector surface would be more diffuse vs. a polished surface but that would not make a big difference at 18-24".
To reflect UVB you are forced to use alu or iron sheets because colors, paints, plastics, glas and all that swallows UVB almost completely. Pretty sure there are UV reflective coatings available but for sure expensive and they would work just the same like any metallic surface. You could polish reflector and spreader surface to optimize UV reflection; thats already enough.
I cut the spreader to fit exactly from the first to the second T5 socket/holder. Then I have made 2 about 10mm deep incisions on each end and bent the middle piece straight flat. I hot glued the magnets to these little flat areas.
I also glued small alu angles to the T5 sockets. The spreader holders has to leave at least a 12mm gap between holder and T5 socket in order to be able to change the bulbs without removing the glued holders. But the best would be you use angle irons from the beginning which are already magnetic. This way there is no need to glue another magnet or iron piece on the holder angles.
Unfortunately I had no angle irons at home so I took aluminum and glued on little iron plates.
At some future point I'm going to replace them through angles made of iron.

Yepp, the Agromax bulbs are in use and therefor I use 30" as minimum distance for the hardening process. I slowly increase the time they get UVB untill they get 2+2h the day(beginning and end of the day). From today they get 15+15mins and until end of next week(switch to 12/12) they'll get 1+1h. I let the plants reduce the distance and LST them later to keep at least 16-20" distance when the stretch is done. I'll add a scrogg net later..
Blue and UVA wavelength have both big impact on nodial stretch but it depends on the total amounts of light they get. Lets say you use 50w 3000°k LED and a 24w reptile bulb(usually 7000-10000°k) the effect would be pretty strong. With 300w warmwhite LED and 24w reptile bulb the effect would be much lower. So it depends on the ratio.
Usually it needs ~10PAR/w per m² of blue wavelength to keep plants short and bushy.
But UVB has also an effect on plant height.
When the UVR8 receptor is triggered it tells the plant to switch in "defense mode" and this has also a few effects. In defensive mode she puts more effort in the conservation of the species than in her size. Plants getting UVB stay a bit smaller but will get more woody branches with higher stability. They also go earlier into the reproductive stage which has also a yield increasing effect and generally they do everything possible to protect the next generation.

Is it me or did the Diesel in the back get more lavender colors? So beautiful

I see them so often, i can’t tell day to day... but, yeah beautiful!
One of my gc buds thinks the qbs intensify colors, and thus lowers chlorophyll content, making for smoother smoke...
I think there may be something to this... uncured haze smokes smooth, clean, gray ash...

Thumbs up, bro! You did a realy good job. All these tops look impressive. LED really help to bring the colors to life because of its blue wavelength. With blurples or additional UV you'll get even more colors..

The other half of the tops:
“Diesels”, this one (front and left), smaller one (back):
Lowers from this “diesel” gonna get some more light.
