Good to hear from ya man, glad things are going well.
Thanks. No I Havnt noticed any difference between hoods. They all look uniform and equally as bright. I should probably break down and buy a par meter. I just don’t want a cheap one so I’ve been hesitant(as I’m a cheap bastard lol).hey eric2028.
just a random thought out of curiosity, can you notice any variation from the reflector connected to the ballast, to the reflector connected by cord? like light color intensity or direct growth underneath? stretching stacking leaf color etc....
looking stellar, liking the newer setup. clean, pretty tight!!

i felt the same, untill i bought one. u can get a nice apogee for $575. seeing the meter show the difference between a year old bulb an a new one, side by side, makes you pony up the money to replace the bulbs. knowing that your yield will go up an you will get the money back there anyways. after all whats 575 .....peanuts compared to what your yield could go up knowing its time to swap.
i will also say i have 24 nanolux 1000w de. they came with nanolux bulbs. there bulbs degraded very fast compared to phillips or the horti de bulbs. i will not run the nanolux bulbs again

That’s the meter I want actually. Do you have the model that does leds too? And you like it then? Yeah I’m not crazy about my bulbs either. When it’s time to swap I ll definitely go with a different brand.

I recently saw a double ended 600 watt cmh bulb on the market. Would be great if they played nice with the nanolux ballast.
There’s a company named Sunplix that sells 1000W and 630W DE CMH lamps. They state they are for use in a square wave low frequency ballast, and those aren’t the most common. Even Sunplix themselves don’t have a matching ballast available. I asked Nanolux about using a CMH bulb in my DE HPS fixture and they were convinced it would go poof so I haven’t tried. It’s about time to change lamps though, so I’m considering giving it a whirl, though $160 for a lamp that might not work keeps holding me back.
Are any of you guys successfully running the DE CMH lamps in high frequency ballasts? If so, which lamp specifically? Worth the change?
In general, is there a favorite amongst DE HPS bulbs? This will be my first time swapping one; I’ve always stuck with EYE Hortilux for HPS bulbs in the past.
Eric— looks stunning as always. In the commercial space you posted pics of, is that strictly a veg area or will flowering be done in the same racks? Are they DIY LEDs or a pre-fabbed setup? Ran across Nanolux’s LED modules and it reminded me of the setup you posted; pretty neat stuff.
you would be correct about running in said square wave verse digital or whatever one would call it. BUT, i am however running a few of the 930w de cmh bulbs from growers choice in nanolux 1000w de setups. these are a few years old already.
since then they started making 1000w de cmh's which are 2 500w elements inline , verse the 3 315w elements inline(what i have).
i have also seen some pretty sweeet 500w de cmh setups over a growershouse dot com ive been meaning to try. im betting 2 of the 500w setups whould do very well over a 4x8 tray.
thou im not convinced the de cmh is good bulb to flower, or my bulbs are just a higher k for veg, i forget. they do throw more heat then the hps, an they have a glass shield around them. they do however throw more umol or par at said watt setting verse a phillips or horti de bulb shown with my meter. i forget the numbers, i wanna say it was like almost 100umol more at 600w setting. which my de cmh never come off the 600w setting running a 4x5 or so foot print.
now that de cmh bulb in veg, fucking amazing!!!
Thanks. Those are the fluence spydr 2i’s. A total of 420 fixtures across 4 bloom rooms (double decker) and a veg room (triple tier). This was the first run so all rooms were filled up, smaller plants vegged in the bloom space this go.There’s a company named Sunplix that sells 1000W and 630W DE CMH lamps.

I run the cheap chinese DE CMH 630w bulbs at 700 watts in my Gavita flex with no issues concerning the high frequency of the ballast.
three runs and still use the bulb in veg, bet they would work fine in the Nanos too...
my 1000w DE CMH Nanos are really bright and I love them.
way better flavor and resin expression than the Sodium DEs for me. I run the 4100K
mine were the cheapest $53 amazon DE 630 CMH in my Gavita the spectrum produces more and better smelling resin and less heat to burn it away.
Thanks bud. I do keep full nutes until 1 week before chop, then just plain ro to flush. My rezs only hold 250 gallons so I change them about twice a week. I normally top up with ro once a week to dilute my nutes to 50 or 75%. Then I flush with that or run it for a day before I do a complete Rez change.Hey eric2028, thanks for this whole thread, it is a huge inspiration for me. I am going to reread it again soon and write down everything you do in a notebook, I think you've got a lot of great ideas and things figured out. Your clone roots are insane, I've never seen anything like that. I plan to not overthink my nutrients and grow and emulate as much of yours as I can until my plants look like yours. Initial tests of the 3/2.5 Jacks mix are going really well. I've never understood why they have the epsom in there.
Can you give some info about how you finish the plants off in the last few weeks? Do you keep running the 3/2.5/0.5 MKP all the way until the end? Flush with water ever? What about CO2, RH, and temps in the last few weeks?
