Atreum is a UK company, right? You can try to look at the Sale of Goods act which means you have legal rights directly with the retailer for up to 6 years after purchase, especially if you can get meanwell to say that there was a manufacturing fault on the driver. Atreum will say no but they...

CO2 is of course also very important for photosynthesis. But in this case, where theres some clear signs of nutrient defs, i would not think CO2 would be the culprit. Afaik theres no deficiency signs of low co2, only slower growth. If you think about it: the nutes we give dont really have a...

Try to get Atreum to help you with warranty service with meanwell, those HLG drivers have 5 or more years of warranty. That xlg driver, is there any screws you could tighten? Or if this push fix is the only way then is there a way you could screw the driver itself onto something so that the...

Your flower nutes, are they also in the soil slow release? That may the problem. The way we deal with these issues is by measuring ec and ph of the runoff. If EC comes out low then just up the nutes. As a general advice id rec using liquid hydro nutes for led grows and if not, at least have...

That type of deficiency could be either too intense light in current environment or too weak nutes. From research it seems very hard to hit the absolute too much light level with any growlight we use around here, but you may have a limiting environment or just too little nutes.

If i were to go for one of these fancy, fastest growth type systems id be looking at making a PPK a la Delta9. Im wary of any system where one pump failure could mess up the whole grow. Any machine will eventually fail, how much it affects your grow dependa on your system and if you can build in...

Yeah, i quite like the idea myself, making a repeated series of strips in order to make a custom spectrum or just save a bit on wiring. I tend to gravitate towards this with lower voltage strips, around 24V / 700mA. That way its easy to just throw in a mono strip in the series that tweaks the...

+1 on filling up driver voltage. A few monos on that string really helps but generally i choose something other than blues, at least something slightly outside the normal spectral range. When i get people to try out our buds every single one can sense which weed was grown with some extra...

It was long time ago though so dont shun those 600w drivers.

HLG > XLG, digikey > alibaba sourced. Sometimes theres been indications that a specific batch of drivers been more prone to fail, i believe to remember a bunch of 600w 48V drivers being fail prone.

Problem is that those drivers will not run in parallel. Or atleast the -M and -H type xlgs. Not sure why but we tried and failed. Spmetimes we could get two in parallel by turning them on manually but never woth a timer.

Nuggfest... Very nice

What was EC??

Do you measure EC of run off? This will tell you whether its too low nutes or lock out. Lock out then flush a bit, low nutes then add some not slow release nutes. High intensity led growing is easier woth hydro nutes.

First of all i dont think your values are critically wrong, you can flower like this all though you need to be careful moving air on top and below cannopy to avoid mold. Secondly, if you want to drop rh at night you can try heating the growspace a few degrees.

Thanks for posting this, very nice.

Im not sure what to say cause my advice would go a little bit against what most people would advice. Yes, for yield efficiency or better said light intensity is more important but the differences in efficiency are quite small, i prefer to just add a little extra wattage to get the intensity and...

As far as i know youre correct but might be a bit different if using different make diodes. This is based on some tests posted long time ago from hlg: 4k and 3k 50-50 results in exact 3500k. I think the reason we see 5k/3k mix is for fabrication/comercial purposes: if you buy 5k and 3k as a...

If you have all the gear why havent you tried it out yet? Seems like the best way to get a baseline. LED? Just cause you got those 600s doesnt mean you can't mix lighting. Try it out, now would be the best time to see if its too hot, and if you feel its too hard to manage then wait a couple of...
