Youre better off trying to find 4x 3x3 lights instead of one 6x6 light. A 6x6 light would need around 1200w plus good light spread; its just easier all around growing with more but smaller lights.

Is the flickering constant and time between on and off always the same? Driver problems. Contact Mars, best off doing it both here and their standard cust serv. Is it more irregular and sometimes affected by you twiddling the dimmer? Dimmer issue which can easily be fixed by replacing the...

Manual method is good, theres not much to it. Just sift a bit of trim, first over one paper/surface, for your first/00 quality, and then sift the rest over another paper. The first that comes out of every batch of trim is always the best

If you run slightly higher temps in your tent your RH is going to go down a bit.

Lighting angles: this would be more true with a bulb/point like light source. The way a bar light spreads the light out with a bar fixture i really doubt that youre getting any benefits for light angles.

Looks a little like led light burn.

It does not create more light, just spread it. But thats something you can already do by using a bar light or similar. Marginal gains at most.

So i hear, something about sulfur as conservation agent for the bacteriae.

Back in the day peeps were doing comparisons and side by sides with Photosynthesis +. I also saw something about some phosphor metabolizing trichoderma here locally but never tried. @jaked3800 how much do you estimate it helped your grow results?

What lighting have you got on this one? How old are the plants :)

Fantastic build, very nice looking. Theres some tests of regular vestas if you havent found it already: https://www.rollitup.org/t/using-and-testing-vesta-strips.988504/ Would love to see them grow :)

Yes indeed! In down cannopy aswell. Though leds nowadays are so rich in green it doesnt really make sense theres a low penetration issue. Personally im not a fan of too green heavy leds, the density is great but it seems to give a more boring mids quality in the product imho.

We had very little extra yield for 240w of side lighting so not sure i would bother with intracannopy; just try for a bit more intensity from up top. However it was just one month of testing.

Fixture size and strip length is a very important part of light intensity: if youre getting lower from your 4ft diys its very possible down to the other light being slightly smaller, thus concentrating rhe light. Fwiw i always spec my lights a little smaller than my cannopy: in openspace this...

Heres the 3D mock up. Ive set up my strips so they can take a standard ledstar pcb mounted on top for any type of supplement you could wanna add. Already have a provider for 4up ledstars so you can get a nice composed supplementation channel. One of the diy-iest strips ive ever seen :) The mock...

Diying for low price has been moot for a long time now since the china lights started taking over in the low price class. I still feel its very valid to DIY for spectrum, function and for very specific growspaces or needs. I can still not find a growlight that has the spectrum and performance...

I have never really seen anyone define what penetration is and how you measure it. 1.5-2g/w seens to be fairly standard for a well dialed in led grow if your lights are on point.

Those are some pretty low yields, more is definitely possible. We do around 750 or just over pound and a half per tray and were a tad smaller than a 4x4. How have you changed your growstyle and environment in order to adapt to your new leds?

If they are long flowering, less, if they are fast (80days or less) more, id go up to 4 in that space but ive got friends who managed 6 in a 80x80cm tent

Things are moving along:) ive got my design finished for a 3 foot strip with some nifty features. Awaiting the 3D mock up for now. Basic features are 420 diodes, 12 of them monos in series of 3, 840x30mm. This fall i will start with some prototypes in order to lock down a good led mono...
