Aaaaaaaaamazing!

Hi Y'all, Having been around growers most of my life in US and EU, I saw growers in the US growing perpetually, always going for big plants with long veg periods, whilst EU, predominantly Dutch growers, would let the clone root and put it directly into bloom in a SOG setting. I mostly know the...

Did you have contact with them? I'm thinking of getting some reptile lights now for somewhere between $2.5 - 3.5/bulb. I've been looking at these. Am I getting my inverse square law wrong? Looking at the 30W f.e. at a distance of 4" they give off 140 uW/cm2 and at triple the distance 12" 59...

Anybody come across the Agric-Ultra MetaRail? https://www.agricultra.com/metarail-uva-uvb-light Can't put my finger on it, but something is screaming BS at me! I believe it's not a light... It's just a pdf.

theoretically... one could actually hang CFL bulbs at 8" or 9" and the LEDs at 18", without creating too much shade.

I'm just worried about the 12" distance.... I just ordered new LED lights from China and I do not think, that I will be able to run them at 12"

Look at those sexy ladies.... The more I look at those plants, the more I'm at risk of a "me too" lawsuit!

Clearly, it would not be used for a closet or garage type grow. Just for research in a commercial facility... and it would need like I said a minimum 2x2 ft beam. That thing could be anywhere from $20k-200k. Am not even going to ask for a price, but having a thing that allows absolute control...

Has anybody checked out the specs on that thing? Would be nice to have one with a 2x2ft beam so you could exactly research every single strain on its particular requirements re light.

I just found my new growlights: https://solarlight.com/product/1000w-solar-simulator-ls1000-6s-uv/ :lol:

There are 285nm diodes, but also haven't found a strip and I have looked for several hours day for the last week. Also for now it makes no sense in getting the strips as they would be more expensive than the bulbs and you'd have to switch them out every 6 months.

Thanks, brainstorming is always better when someone is helping. ;)

Thanks, but fluoros, besides Exoterra are not available in this country. But the sample thing I'm aware of. Just a little problem, if I order 32 units or so... Customs are sticklers in this country.

280nm is a bit scary. Searching on alibaba for 285nm LEDs, they will pop up... trusting them is the big issue. We pay around 30% customs+vat, so having samples sent from different suppliers would dry me out quick.

I just discovered, that I can't get the Solacure in South Africa, so I will have to find alternatives. Any 285nm LEDs or other bulbs out there? Arcadia are also not available. Frustration is setting in. Getting UV lights here seems to be a turd gone sideways.

The Philips Actinic are not for psoriasis, they would directly cost way more, if somebody really needed them. The Philips are for fly zappers.

Yes, I mainly liked the price and the ability to go higher with the UVA. I like the idea of being able to adjust the UVA to UVB ratio and keeping them separate for better control which allows experimentation.

Yes, besides having the perfect UVA peak, the price is what I noticed as well. They have UVBs that start at 305nm, but that is sadly missing the 285nm and since they are used to treat psoriasis, they are around $100...
