thanks! no, in a large room.Are you putting these in a tent? Running a 1000w gavita DEHPS in a tent is not realistic at all, you need a lot of vertical height. The sunsystem AC/DE hoods are more suited for running dehps in a tent.
Id look into the HLG 600 kit instead of the HLG 550. The hlg 600 kit is $723 prebuilt, and is 620w versus the HLG 550 which is only 510w.
The HLG 550 is closer to a replacement for a single ended 1000w hps, but will definitely give a gavita a run for it's money. The HLG 600 kit will definitely replace a 1000w gavita.
The LEDs will save you a ton on your electricity bill, they'll put out WAAAAAAY less heat, you'll run less risk of light bleaching your plants, you'll actually be able to see your plants under them, and in my opinion will increase quality across the board. Oh, and you'll very likely see higher yields too.
edit: forgot to mention: You can actually veg under the HLG light, whereas you'd be silly to veg under a dehps lamp.
one uses $300 less electricity per year and doesnt require $50 a year in bulbs, and cuts investment in cooling equipment by 40%1000$ vs 400$
powers same space
awesome, i agree. ill bring these points up. mathematically no brainer.Yeah, i dont understand why the 550 costs more than the 600 but is less powerful, makes no sense.
Yes, you can hit 2 grams per watt with these LEDs if your setup is dialed in. If your team is hitting 2 gram per watt with gavitas, they'll easily hit 2 gram per watt under these LEDs.
I cant give you a full on energy savings that includes AC and all that, but just running the 610w versus the 1063w a gavita pulls, you'll save approximately $225 a year PER LIGHT @ $0.10 a kw hour.
Once you factor in the savings on AC and ventillation, it's gonna probably be twice that or even more savings.
didnt know each gavita needs 50$ lb replacements per year, thanks for that.one uses $300 less electricity per year and doesnt require $50 a year in bulbs, and cuts investment in cooling equipment by 40%
You bring a good point there. So are they pulling 3 lb per 4x4 table with the gavitas right now? Because that would be closer to 1.3 grams per watt with the gavitas, not 2. Ive never seen or heard anyone pull much more than 3 pounds per 4x4 area either. They will definitely be able to pull the same 3 pounds under the LEDs though, using about half the energy.awesome, i agree. ill bring these points up. mathematically no brainer.
as for the 2g/w for hps, thats a little misleading with regards to LED since we are naturally using half the amount of wattage per 4x4 space (1000 vs 510 or 600 watts) so per 4x4 space we will be running half the amount of overall yield as hps. is this correct or does it somehow equalize in the end (3 lb per 4x4 hps and 3lb per 4x4 table led)?
Are you sure about this? At what foot print? At what height? I thought the HLG 600 kit was close to a 1000 watt single hps?but will definitely give a gavita a run for it's money. The HLG 600 kit will definitely replace a 1000w gavita.
Most likely double. I paid 100 for the phillips$50 a year in bulbs
Here is the PPFD data for the HLG 550 in a reflective tent @ 22"Are you sure about this? At what foot print? At what height? I thought the HLG 600 kit was close to a 1000 watt single hps?
What about demand for dehumidification that apparently goes though the roof when running at higher "led appropriate" temps?one uses $300 less electricity per year and doesnt require $50 a year in bulbs, and cuts investment in cooling equipment by 40%
But this never happens though. Thanks for the infoThe PPFD of the gavita at 24"
Actually according to Jair [owner], he is constantly stressing replacing glass and bulb at the same time after every run or 3 months whichever comes first.didnt know each gavita needs 50$ lb replacements per year, thanks for that.
not a given at all. every room is different and you cant equate VPD with a given light source based on all the different climates and growing styles out thereWhat about demand for dehumidification that apparently goes though the roof when running at higher "led appropriate" temps?
thats based on the cheapest bulb replaced once a year, im being generousMost likely double. I paid 100 for the phillips
they were estimating conservative ~70lb for 30 4x4 tables, so ~2.3lb/table.You bring a good point there. So are they pulling 3 lb per 4x4 table with the gavitas right now? Because that would be closer to 1.3 grams per watt with the gavitas, not 2. Ive never seen or heard anyone pull much more than 3 pounds per 4x4 area either. They will definitely be able to pull the same 3 pounds under the LEDs though, using about half the energy.
can u redo this assessment using realistic height distances for the gavita? heard they are always pretty high up due to the heatHere is the PPFD data for the HLG 550 in a reflective tent @ 22"

And this PDF has the gavita 1000w DEHPS PPFD data in a reflective tent taken at various heights, including 24"
https://growershouse.com/images/DE_TEST_INFOGRAPHIC.pdf
The PPFD of the gavita at 24" is literally identical to the PPFD of the HLG 550 at 22".
And keep in mind the spectrum of the HLG 550 is vastly superior.
How convenient, did HLG share this document with you on their website?Sadly I can't. I pulled that off of HLG's website
