Thanks for the compliment. These grows have been averaging around 300 grams p/meter. much lower temperatures in the room and I've not had a spider mite issue in four grows. So the HID probably made that a favorable environment me thinks. Pics as requested!Quote:

:wtf: First pic looks like it's still in vege,.... 2nd,.... well there's no size comparison, but I've gotten better off of my HPS.Quote:

So the jury still out or has someone out there put a room to head and can show us all some pics
Thanks

If calbunn claims his "400w" induction can match a 1000w HPS, then my "120w" induction ought to match a 250w HPS.Quote:

Mland brand and super grow unbranded look the same is the unbranded super grow the same lamp, all these things look great as we all know the big question is do they have enough power to penetrate deep enough to produce good big bud.So the site that sells the Mland is the same one that sells the LEDS and well I don't like em .
What about the INDA-gro is this the same concept as the others how dose it compare
Thanks so far All your ideas have been helpfull

Here is a link to our a grow with a Parmax EFDL 200 watter 2700K YouTube - Inductiongrow this is at 5 weeks of flower but you can follow his other post from the beginning. I have spent the last few months figuring out a couple of serious issues with induction lights. First the ballast were overheating and causing the lights to flicker after about 6 hours of operation. This eventually blew the ballast. the second issue was the bulb would lose output to about half brightness after a few hours of operation but was fine when it cooled down. Well after countless hours we finnally addressed the issues and had our manufacturer fix the problems according to our directions.(wasn't easy with a language barrier!!)
Since then we noticed a few new importers introduced a new induction light called the bispectrum or super grow light. The bispectrum light is a combonation of two different phosphours to produce one half of the bulb in 2700K and the other half with the dreaded purple color spectrum. I have attached a copy of our 300 watt spectral distribution test along with the bispectrum spectral test. At first you are going to be blown away by the spectral graph of the bispectrum test, but if you continue to read the report, you will find that the luminous efficiency is only 10.4 lumins/watt (although resellers are quoting 40 lumins/watt) sure the spectrum looks great on both red and blue scale but light penatration is a big issue with these lights. If you compare it to the 2700K 300 watt test you will see that the light efficiency is much better at 81 lumins/ watt and punching out over 33000 lumins. With a bit of tweaking , we believe we can get the 300 watt 2700K induction light to come close to 800 watts of HPS. If you read the 2700K test you will see that this light peaks at 615nM and peaters off in the far red. This is very close to the spectral distribution of HPS except the HPS has more in the green and yellow range and also lacks in the far red. My idea is to suppliment the missing wavelengths with LEDs. We are going to build a 300 watt EFDL with built in supplimental led's. I'm hoping to add about 50 watts of led.
There are a lot of sceptics out there for these lights so what i'm going to do is i am going to give this light to a lucky cadidate to do a nonbias grow journal anyone interested? We already know our 300 watt EFDL 2700K works and keeps up to 600 watts of LED and HPS but i'm confident the added spectrum will knock this light out of the park!
I'm still trying to source a supplier of LED's so i should have this light ready in about a month.
I'm having troubles loading the bispectrum test it seems too large a file i will try to shrink it
Thanks for that info bubbas. Looks like a great job your doing .In your opinion the "super grow" Light(Mland) would not work as well as yours.and would you say the INDA-Gro is much the same as what you are using.
Hi Hilights,
I can't say for sure the new and improved bispectrums won't work as well as standard spectrum bulbs but their specifications sure point in that direction. I testd the first generation all purple lights and they were terrible. They like first gen LED's vegged well but fell flat on the flowering so to improve it they made half the bulb in 2700K. I don't have a lot of info on the inda gro. i see they have 5250K. This color is a full spectrum color that has blue and red spectrum in it however more in the visible range of green and yellow light and less red but decent blue. I would suggest to ask them for a spectral power distribution test data. Their grow light fixture does look better than the Mland as there is no glass and the ballast is out in the open. The mland fixture is actually a tunnel lamp fixture. It has the ballast fully enclosed within the fixture and a piece of glass to protect the bulb. It's IP68 which means its waterproof but why? are we growing outdoors? It only causes overheating issues. We had overheating issues even without glass and our ballast was not enclosed so having it IP68 would make overheating matters worse.Don't get me wrong, i'm not saying others are shit so we can sell more of ours but we don't want disappointed growers who spent a lot of cash for these lights and have them perform poorly and in return telling the world that induction lights are crap. We know they work and are in the next stage of improving them to work even better than any other grow light out there.
We look at HPS and MH lights like old 60's muscle cars, Lots of HP and gobbled up fuel like there was no tommorow. LED's and induction lights are like the new gen of muscle cars more hp but sips fuel. Did you know that Hyundai's sport coupe is quicker than almost all the 60's and 70's muscle cars but still gets 30MPG that's technology!!
