I have to add swamp coolers here with the dry climate. I have dehumidifiers and they never get plugged in lol

It seems most running a sealed environment are traditionally relying on their A/C for a good portion of their humidity removal. A/C "running less" = Humidity increaseIs that a problem most people would have or just those in high humidity areas? I'm guessing that you'd just fan more if the exterior humidity was less than your target.
Maybe just add co2 insteadallows for more humidity is what I read.

They've made LED specific and sunlight specific par meters. Are you referring to something beyond that?

He's referring to way beyond that. "par" does not break it down to all the spectral wavelengths

I own a fuck load of test equipment, alot more than any of the companies you guys see selling led products on here although they should spend some money and try to catch upto me. I don't believe that the current way of how horticulture lighting is measured is correct, the math doesn't add up to me at all and I believe we are missing alot of readings that we should be talking into consideration.

Just did some googling and Bruce Bugbee is currently proving you right. Except that it does break down all wavelengths, it just doesn't include combination effects and intensities.
We'll have an updated "par" spectrum soon.

It will take a lot of studies and a very long time to figure out what does what and even then I believe will still be strain dependent on what works best. I am convinced that PAR as it is measured at the moment isn't the best way to judge efficiency. We are definitely missing something in the equation.

Ya his video only says they'll have a "proposed" new PAR system when he's done this round of research.

Ssu sounds dumb. It includes all infrared as part of its measurement. Only so much is needed to achieve the Emerson effect

What I learned about the impact of infrared in regards to the Emerson effect is that it is only useful as a small percentage of the light. So something that measures that range of wave lengths will have to single out that wave length and then calculate its percentage of the whole and negate any readings beyond that. Not easy or cheap. Moreso when you have other cumulative effects to single out. Instead, if you can measure the light that is directly used and "multiplied" if you will, which is the 450-650 range, then add in a spectrometer to check proportions of UV and IR for your particular effects. Which is what they currently do. Works pretty well.

finally did it. my digilux mh 600 bulb stopped working like they always do alittle after 1 year, switched to a genesis mh 600 and wasnt happy with its output so i ditched the MH's for first time ever in 2 decades.
Replaced with four 132v2 4k qbs and one 120 4k qb in middle, layed out like a #5 dice. Running at 350watts(280w/132qb's and 70w/120qb) at wall. Much nicer spread of light and noticeably brighter to the eye and my meter show more consistent numbers all around room.

If you could post back here in a month with a follow up on how your feel the growth is vs the MH

So it's been a month. I switched back to MH. I bought a new genesis bulb and it seems to be 4k like digilux, my old genesis bulb that i replaced digilux with was alot more blue around 6500k and must have had good amount of hours on because new one is 2x as bright according to meter. In a xxxl hood the new genesis 600 has same spread as the 5 QBs did but plants just liked the MH more for the purpose I need in that area. I use QBs in my genetic tester areas that are smaller then my main perpetual veg room and they work great in them with smaller plants but when I'm prepping plants to be 6ft+ in the shape of bouquets(8+ tops)the MH does a better job for me in this situation. I still love my QBs, have 7 of them still running.If you could post back here in a month with a follow up on how your feel the growth is vs the MH

Thanks for the follow up!
I've been running Ushio 600W optiblue in veg and love that lamp as well. Was using hortilux blue but the 600W version is too red heavy and causes undesirable stretch in veg. The Ushio lamp is much closer to 6500K T5 in spectrum

Isn't the ushio a conversion bulb at only 47000 lumes? Genesis is a real 600 MH and 75,000 lumes, only one I know of on the market since digilux is gone. Check them out if get a chance at Monster Gardens(there shipping is great). I've used other conversion 600 MH's and there's a noticeable difference in brightness and growth rate then when using a real MH like genesis.Thanks for the follow up!

ALL 600W Metal Halide Lamps are Conversion Lamps
Ushio doesn't talk Lumens. They talk "PAR (ΜMOL/S):" - the proper horticultural rating
