Alfalfa and tria are two different questions imo, as lots of people seem to use tria til harvest with no problem. This is my third season outside using alfalfa and kelp tea, drench and foliar. I love it and use it till about a week into september, max. This year i planted autos alongside the...

I've been using getdata and ran a citizen clu058 2700k 90 cri through it and have gotten some weird outcomes... Manually plotting and using the technique Rahz described is simply not working.. totals way over 100%, even when adding and averaging, and wildly differing results based on number of...

Delicious! I have to learn to do those.. Will be playing with the software mentioned.

I'm looking at various clu058s and trying to decide which to try. And trying to make the spd data something i can compare to other stuff im reading. The first graph in this post of yours is what Im after https://www.rollitup.org/t/cri-test-and-mcree-weighted-results.919923/page-2#post-12931024...

Thank you.. Ive Been searching but I cant find software or spreadsheet to do what you suggest. I also cant find the process to do it manually :wall:

Im just trying to correlate what I read (e.g. 10% of total ppf in 400-500 range) to the spd... Somehow i thought a great deal of conversions would be neccesary

Thanks mate.. Is that expressed as % of total ppf? It just says relative intensity on that axis.

Hello, i'm looking for a formula to figure out, using manufacturer specs, spd or other, for example - percentage of total ppf contained within 400-500nm. Thanks

Pg 8, radiation characteristics http://ce.citizen.co.jp/lighting_led/dl_data/datasheet/en/COB_5/CLU058-3618C4_P3373_1115.pdf Solving for Y in above sketch is @27degrees x 2 = 54 degree total spread to throw all light on canopy and not onto the walls of the dead zone between light and top of...

Solve for angle Y

Optics? I reckon im not looking to focus the light with reflectors.. 4x4 with 7' height. Diffusers? Sorry boys i cant like posts yet

Well now to figure out airflow, heatsink and fan size.. Got a 760cfm inline i hope will cool this thing and suck thru carbon.

Sick.. That looks like a sentient being. Weed, sorry about the poor sketch, my hand is a meatball with 5 sausages. Basically a std 8" duct used as a manifold, closed on one end, with 4 1-foot hoses that fit over the heatsinks and vacuum it. Looks complicated but just a few holes to cut and...

Approx 24x24x8" for a 4x4 room. 4x@150w clu058 on 2 meanwell hlg320-c2800. All the room air sucked through the heatsinks. About $450 plus duct and wire. Thoughts...thanks.

Hey Beast, any updates? Just saw your question about transplanting.. Definitely give it a week or more before flip to fill the bucket w roots.

I got a really late start this year so I bought a bunch of autos.. First time. Looking for a dank cheese photoperiod keeper too.. Dina and kaliman are what I'm looking at.

Hey Candy, I'm pretty impressed by that bush. Your training skills are certainly up there. I have one dinafem cheese xxl auto outside and it's in the top three out of 12 plants in growth and size. Please keep updating...

Great, thanks to you both.

Hey yall, First time here at RIU.. I'm impressed with the crew here. Former overgrower, current icmager, and long time agricultural worker here. Got a little scrog goin, and its my first, I'm almost ready to flip. I've done a lot of reading and tried to search, but my questions are specific...
