comparison grow: HPS vs Induction

[El Cerebro]

With the rising cost of power and the need to keep temps induction has found a seat at the table. But the system of choice does not necessarily have to be an Inda-Gro. In the interest of finding the best value for the grower I've done alot of research before deciding on growing with induction lighting and I would strongly recommend anyone considering this technology do the same. If you decide on induction than you should look for the following;

• Check out the published Spectral Distribution Graphs (PAR spectrum values between 400-700 nanometers) the lamp emits are everything to make sure the lamps phosphors meet your methods and plants needs.
• Does the lamp spectrum design require you to buy two lamps (one for veg and one for flower) as opposed to a broad spectrum that allows one lamp to take the plant from propagation thru flowering/bud?
• How long is the warranty and where is the service done should I need repairs?
• Make sure the lamp/driver is UL rated since the surface temperature of an EFDL @ the glass runs around 200 degrees F (93C) and the driver housings will run around 115 F (46C) then check it @ http://database.ul.com/cgi-bin/XYV/t...AME/index.html with a company name or the actual file number. If they do come up in the UL data base you're at least assured of the highest standards for safety compliance have been met.
• Does the company discuss their products in terms of plant lighting and not kelvin, lux, footcandles or lumens?
• How much PAR energy does the lamp produce (PAR Watts) and how much of that energy makes it to the canopy?
• If they are merging or fusing a red and blue lamp together and promoting a veg and flowering spectrum stay away. It's a marketing gimmick that has literally nothing to with with veg or flowering PAR spectrums.
• How is it in terms of housing and reflector design for canopy penetration?
• What are it's physical size and weight?
• Why some of these lights come with a glass cover for an indoor growing environment is a mystery to me but if the light comes with a glass cover is the manufacturer okay with you removing it and is it still protected under warranty?
• What is the area of coverage and what are the recommended canopy to lamp measurements within that area?
• How much heat does it produce in terms of BTU/hr. While EFDL lamps run an average of 3X cooler than HID you'll still want to know this so you can factor ventilating and cooling of the room.
• Do they have any videos or comparison grows they can point you to?
• Do they have a website devoted to their EFDL products for grow that goes into detail as to the technology and how it should be used for indoor gardening?
• Does the unit come fully assembled and ready to use or do I have to do some assembly such as installing cord ends or installing a housing or reflector?
• Is it rated for the supply voltage for my particular part of the world I'm planning on running them in?
• Unit cost delivered after all shipping and handling.
• Total unit cost should you have to buy additional materials to construct your own housing and reflector materials.
• Does the company offer any quantity discounts?
• Types of payment accepted. If they don't take cc, paypal or google merchant be very careful since other forms of payment like money orders or direct deposit can't be protested should you have a problem.

The following links are for reference only as they are companies or sites I've come across that make an EFDL lamp for indoor growing applications. I'm not criticizing or endorsing any of them. They are not listed in any particular order or rank. Do your own research first before buying anything.

Happy Growing!

Hey Daryl @ Indagro, one day when i'm laid up and have time, i'm gonna post up a big list of all your shill-ass forum posts all over the web the past 5 years, so everyone can see them in one place. And see you for all your manipulative, back-door attempts at social-engineering in order to sell these products.

What he's doing now (just recently since the last max yield shows), running around forums/youtube talking about other induction mfgs in an attempt to legitimize his own brand. If I was your competitor and you posted up an ambush trade-fair youtube video using me to help sell your products (like you did to that i-Beam guy), I would call your ass out, right there on the spot and in front of all your industry peers.

Main question i have, why the fuck can't you just come out and discuss this shit openly without all the multiple logins and tag-team guerrillamarketing with that growlightsource.com guy who also lies all over the web pimping your lights?

I mean seriously, there have been a bunch of us here genuinely interested in this tech, and I can only imagine the number of non-members reading this thread too. All your lying and deception on this has been really frustrating for those attempting to honestly investigate induction lighting. Furthermore you have singlehandedly contaminated (arguably all) the online grow-forum discussions on this subject with confabulatory bullshit.

All this when you could have just come out in the open and sold your product to us honestly for what it is. Had you done that, I bet there would've be a bunch of us willing to spend our own $ to test them in various configurations. But instead, you've kept up a 5yr set of lies you can't back out of now. Fucking sad.

 

[Splifferous]

wow does this moron ever quit? i'm asking because it's been months since i've been here and this guy is still acting like a raging fucking douche.

for what it's worth, heres my recent bloom update. 3 420-PARs in a 5x10 tent. HPS can suck it.

and that's me talking... i'm not Darryl, not Chaz, nor anyone else... feel free to click the youtube logo there, check out all my other videos too, i talk in most of them.

and Cerebro, i gotta take issue with your trying to claim it's been anyone but you contaminating the topic of induction lighting; it's utterly laughable. Darryl is the ONLY manufacturer of horticultural lighting that i am aware of that will show their face in a video that also contains cannabis. and speaking of industry peers, who would you count among yours? for as many of your posts as i can stomach to read, i have found NOTHING of worth that you have contributed to these forums. ever. for all i know, you probably work for some HID lighting manufacturer and are acting all butt-hurt and sand-in-the-vag because you know that EFDL is here to stay and HID is obsolete since inception.

you can leave my post here, or take it down and shove it for all i care. this site is pathetic and i will not be back.

take a bow, Cerebro. you are a fucking pair of clown shoes, bro.

Here's a licensed 99 plant dispensary garden doing the seed to sale that got started from seed on a 3 week 18/6 veg. The room is 20 x 25 (500 sq ft}.

Strains: Blue Dream - Platinum OG - Hash Plant - Athena Kush - Fire OG - Louis the 8th - El Diablo OG - San Fernando OG - Abusive OG

Here we're at day 37 of Flower on a 12/12 cycle. This entire grow has been run on 12 of the Pro-420-PAR lights from vegetative through flower. Total wattage of all lights is 5,050 watts. Total connected watts when compared to the previous 1000 watt HID system is less than 1/2 when considering the reduction in AC and lower wattage lamps.

More to come...

 

[swisscheese]

Chaz nice pics but everything looks underdeveloped and fluffy for being 37 days in compared to what I'm used to with hps. I would love to do a side by side to see for myself and don't get me wrong your flowers look nice and tasty. I'm not a believer yet though.

 

[chazbolin]

On this particular project we're limited by the amount of available power for the entire dispensary. So filling the grow room for the 5050 watts was the only way to accomplish what would have been the usual 10k watt mh/hps run and a portable 36K BTU AC which is another 30 amps @ 240 which I didn't have. So at this stage it is what it is. But I will say they're plumping up nicely though. I'll try to keep up on the updates.

Here's a run of G13 and Violator Kush that consistently comes in at 130-140g per plant putting each light @ 1.2# per fixture on a 55 day perpetual.

 

[chazbolin]

G13 day 56 images are just prior to harvest on what had been an 18/6 veg for 6 weeks and it has been finishing about 7 days earlier than when we ran the same strains under previous 1000 watt MH/HPS grows.

I had 12 large plants spaced under 3 Inda-Gro 420's with each plant yielding between 130-140 grams making 1.2 lb's dry per light. Now I'll be going to a 2 week veg and a sea of green style that will allow 13 smaller plants under each light. Using this method I would expect the yield to go up from there. We shall see.

 

[jkbeing]

From what I have read and seen I would not buy one of these lights. fwiw.

 

[chazbolin]

Day 42 update

This room is being run on 12 of the Pro-420-PAR lights from vegetative through flower on a single lamp. Total wattage of all 12 lights is 5,050 watts. they produce 1/3 the heat of an HID system so there is no ducting the lights. Of note: no CO2 is being used on this run.

Strains: Blue Dream - Platinum OG - Hash Plant - Athena Kush - Fire OG - Louis the 8th - El Diablo OG - San Fernando OG - Abusive OG

 

[jkbeing]

And how much yield are you expecting? Not counting larf.

 

[chazbolin]

I'll post up once dry but I'd say between 12-14 elbo's top shelf

 

[jkbeing]

Really, your canopy isn't even at all and your still pulling those numbers? Please post up some pics when it's all dry, will def help me start believing this.

 

[chazbolin]

I plan on posting final weights and yes the canopy is not even but there is excellent air movement and the lower branch development is healthy and sugary so I expect numbers in those ranges.

Gonna get another CO2 controller for the next run. This one took a shit so we're doing without.

Today's day 47 bud porn....

 

[jkbeing]

Is it me or is that a whole lotta leaf? I just came from GhengisDon's awesome thread and his bud porn is all about the bud. Am I missing something with you pictures? I will be comparing your final bud shots to his, if you care.

 

[chazbolin]

Not familiar with that thread. Where is it?

 

[chazbolin]

I had my AZ bud send me this vid on their new SoG setup. They shortened veg from 6 weeks to 2 so they're thinking their going to harvest 10 days sooner this way.

She tells me on a previous run they lab tested the G13 @ 23.5% and the Kush @ 23% THC--and that was when they had thrips. In this video her husband believes they'll push 30% from the "look" of more sugar but that has not been proven. The 23.5% was proven.

Day 52 update. Last pics before we chop this weekend. Battling a case of PM but all in all looking pretty good. Bud density is rock hard, sugary and stinky good. I'll be posting up final pics and weights as I get them.

 

[chazbolin]

Athena Kush @ day 56 harvest

 

[growingold]

I have been veging under the pro 420 for the past year with really excellant results I have just taken them into a flowering room and I will find out for my self if they will produce .I am using 2 420 and a 150 watt kessil led for 8 plants I will let you all know .I usally use 600 watt hps for flowering so it is going to be interesting

 

[WeedsterBunny]

I am trying out a different company's induction bulb I bought that is distributed in the US and has University and USDA testing. Check them out for yourself www.igrowlights.com lots of good info and vids on their site that I could regurgitate but I'd rather not do it here. I will probably try to do my own thread for the next crop starting in a few weeks. First I had to see if the light actually performs. I know I'm a "new farmer" on this site (or any) but that's really just because I had only been growing with 1000 watt HPS (commercially and personal) in soil before and there wasn't really anything I needed to say or ask that I couldn't already find in books or online. See ya in a few weeks :)
