I check that the UVB tube worked properly.
They are set to turn on for 20 min a day at 3 pm, i will increase by 20 min a week or until i noticed heavy leaf stress.
(Light were turned off for the picture)

Plants are looking good, lifted a bit the lights.
I noticed some roots seems to be drying up as they might not get water as other toots cover them, hopefully no root rot will take advange of this.
Their week of transition is done, entering flower week tomorrow.

Decided to try the emerson effect to increase yeilds, changed the light schedule to 7h30 to 9h00 pm with some far red for 15 min after lights off.
Used 2x 730nm chip of 50w each.
We see if it works, i had to put the light at the top of the tent to have a full coverage, but this cause half the light to be lost by main light under it.
Apparently it doesnt need a whole lot so im hoping they wont reveg with the far red.

I have 2 RapidLED 730nm that I have used on my last two grows. I run them 15 min before and after lights on/off.
It’s hard to tell if they increased yields as I grew different strains each time but I definitely feel like it helped initiate flower faster with more rapid bud growth.
I’m interested to see your results and thoughts on how they work.

well im giving 13.5h of light instead of the 12h, hopefully that extra 1.5H of light a day will give more weight

Consider running a comparison sometime where you create clones and one gets the far red and the other doest to try and validate the theory. It is an interesting concept...
Yeah i still struggle to start clone, wish i had the space for multiple tent to do more experiment.
