Canna Aqua Vega(ryzotonic and cannazyme also) with a bit of cal/mag. Day 56.
2 plants(Gelato) at the half way mark in my tent. The day it was switched to 12/12 and Canna Aqua Flora.
It looks like a large yield grow for a small room and 2 plants...

Could I see a pic of your light? It looks like a cool little build.
That is a sweet light. I made it. About 3 years ago. It has been used for many successful grows.

It is 5 Cree CBX 3590(3500k) cobs run on a 250 watt meanwell driver. For 50 watts per cob, which can be cooled passively(heatsinks instead of fans). I have the driver(powersupply) outside the tent for temperature control reasons(the driver gets hot).(that center led...I was told to remove the hood for a more even coverage reason, if you're wondering...)
This tent/light combo is killer. There is PLENTY of light, which I think is a part of dankness.

And you sound like an ignorant child, thanks for making it personal. Now I can take the gloves off.

...I am kidding about that, I have no interest in having a war of hurt feelings.

I care very much about precision of thought, however.

Sloppy writing is evidence of sloppy thinking, and sloppy thinking leads to sloppy doing. I am sort of a crusader for better thinking, for which I will not apologize.

I promise I am fun at parties, bend over, I’ll show you :oops:
Well played!!

What does something like that cost to build? How are your yields?
cree chips are like $30 each - $150 for 5
140mm passive heatsinks are $19 each, $95 for 5
could probably run all 5 on a hlg-240h-c1400b pushing the driver to the max, that would be 50w each like he said, $60
then the power cord, wire connectors,wires, aluminum for the frame, could be up to $40
then tax + shipping

my guess is he spent a minimum of $350 building that and that is worth every penny

This is considered "old" now...
3 years ago this was cutting edge.
The cost has dropped, more efficient running, better numbers.

Cost:
About $100 per cob. Give or take.
The more cobs you add the lower the cost due to getting one power supply(driver) for all the cobs.
This one cost me about $400

We are stretching now...
These put on an easy 6 inches since that last pic...a week ago.
You can kinda see the one in the front is stretching more than the one in the back.
Gonna start stripping lower growth soon, but not yet, I was taught that as long as the leaf is green, it is providing for the plant. Until the flowers actually form, I will leave it alone.

Can't. We are in flower. 10 days in.
They were pinched like 4 or 5 times during grow. Between the 2 plants, there is 12-14 useable tops
This Gelato is reported to double in hight during stretch. Left enough room in the tent for the doubling.

I measured the tent from the top of the pots to the filter/fan in the top of the tent less a couple inches for the light(it has a small heat/kill zone)and drew a line at half that. When they reached that line with an even canopy we went 12/12 and changed the nutes to the canna aqua flora line with boost and 13/14pk. That was Aug 27.

Drop the 12/12 line a few inches on the next run?

You are probably right.
I did not want to waste room, so made sure the tent was filled. Perhaps I got a bit...greedy. Underestimating growth seems to be my way, most my grows end up with a bit too much no more room.
At least that is an extra high tent(one of those that has a 1 foot extender on it).
Also never grew this strain before, so its an unknown. These were all the seeds I have of this too, only had 3 and one didn't pop, so decided to get these 2 to make up the shortfall.
