They are suggesting 2 shoe box Canna+ units in each 4x4 area. At 392W each that's 784 watts per 4x4 with an average of 861.05 μmol/m2/s. These would be run 18" over the canopy. Alternatively 4 Canna+ 120 light bars in each 4x4. At 139w each thats 556W per 4x4 with an average 807.65 μmol/m2/s...

It would be ballpark $60k to outfit my 1000sf operation.

Uhhh.. no, as nice as they were, I just couldn't justify the very high cost to outfit such a small grow.

Spoke with them on the phone this week, excellent contact and customer service definitely. Got a suggested layout and pricing. A combination of their two cannabis lights, bars for veg, shoe boxes for flower. They remind me a lot of fluence but with a lot more scientific study of their products...

As of now our law does not have specific facility or lighting requirements, of course that could change with new legislation in 2019..

If I want to be able to pay $1500/month for crop insurance it would be necessary. At our size/scale it's not worth it IMO. This build is 1100sf in a new market, basically a proof of concept to see if it's worth pursuing a large scale buildout. Also we are hoping to yield more than half our...

If one believes that efficiency is still king, then a full spectrum white light that will hit 1000+ppfd at ~2.5µmols/j with around 600w that you can cover a 4x4 with for $600 is as good as it gets.

I guess the counter to this would be that one could very cost effectively add some far red 700-800 nm to the samsung quantum boards and essentially have the same light. Same could be said for blues, infrared, etc. The advantage that has drawn me to HLG (besides price) over fluence, electric sun...

Even Fluence (arguably the biggest most influential commercial LED grow light company to date) tells you their exact spectrum and what a light costs on their site. I guess my thought is, is a light that is 5-10% better worth 200-300% more $... Maybe it is. I am just observing this industry from...

This is the same thing Green Sunshine Company (electric sky) LED grow lights does. They have a "Patent Pending Proprietary Spectrum" That is their big selling point.. It does weird me out. I also dont like it when companies wont tell you the price of their light.. "contact us for quotes"...

I do appreciate the alternative perspective. I will look into this info before I make any comments on it. I have been thoroughly researching LED lights for about 6 months now, but can't say i know anything about this company. As far as UL certification.. I have gone round and round with that...

In my experience (which is relatively limited) most of the G8 and Viparspectra lights are about as efficient as the cmh you are using. So you will not save any money in electric usage, but you may save a little on cooling costs. The G8 600 pulls around 350 watts, the viparspectre only pulls...

HLG300 V2 is a sexy turn key lamp, the HLG 320 Watt XL is a kit you will have to build.

Know anything about this PAR meter? We were about to order some ventialtion supplies and it has decent reviews online: https://hydrobuilder.com/sun-system-par-meter-with-remote-sensor.html?___store=default

That was my gut till I started looking at 96s, thinking I should just go that route for simplicity sake

Yeah, we have been shopping PAR meters, I just need to bite the bullet, pick one up, build these setups and test them out. I was kinda just hoping someone would show up and say, hey I did all that, here is the answer lol.. I've been following the QB96 Elite threads, and the PAR tests that have...

Thanks guys, we are filling a room with 9 x 4'x8' beds, so that's 18 4'x4' grow areas. Ceiling height is 8' Our original plan was 6 QB288 with 2 320W drivers in each 4x4, but they are sending us 32 QB96 Elites to check out, and I like the idea of adding the red spectrum, just not sure if it's...

Thanks, I will try that!

Hello All! We are a newly licensed medical grower, looking to get some opinions on a light setup. In personal growing I have tried many different LEDs and we are sold on HLG products, love the quantum boards. We have come up with several potential layouts, these three are the top picks. 1.)...

The new QB96 Elites are worth looking at. 4 in a 4x4 would be intense. The Triple heat sink with 3 qb288 kits are badass too.. I also have a 600W kit, it is a fantastic light for a 4x4. More affordable than the HLG550, which is a badass light too, the 550 was on sale for $800 in October If...
