Growershouse is probably your best bet for the 315's, I've looked around for them in Canada and best price I could get up here was $700 CAD. For COBs there's a company in BC using Cree 3590's with decent pricing, probably even cheaper than DIY kits out of the US.
Growers house does not ship to canada from my findings
If they don't now they've stopped, I bought 2 from them there about 6 months apart. Another was https://www.bghydro.com/ I bought a bunch there for my son as they had a better volume deal.
Hey ganja...did you ever use that same room with Hps de lamps? And if so what total wattage did you have? Looks damn nice...any lamp.
I haven't. But next crop I plan on putting a row of 3 of them down the middle of the room to see if they really make that much difference in yield. Luckily I have 36000btu so I can play around with that.
By far. On average a 630 LEC only needs 2200 btu. Gavita claims it's units only need 4000 but it's closer to 5000. You could get away with running a portable AC in a small room for 2 lights. They are no LEDs but still cooler than anything else I've run by a lot. In veg I run them at 60% the room never gets warm. Running the 5 I have now at 10% overdrive and having no problem cranking it down to 50 degrees if I wanted.
Keep a couple bigger bulbs around to add heat in the winter. Don't have a laser therm however to the hand I would say by wattage standards a 315 feels half as cool as a 600.
Iam in Michigan. Freezing cold outside this time of year. I have a louvered intake that i strictly use for this time of year. I shut off my mini split the whole winter. I thought it crazy to run the room with the split on these months when its 25 degrees or lower outside. Saves me bucks. I have a six inch inline blower hooked to a simple themostat hooked to the louvered duct flap. Keeps it just as cool as the split...virtually no money spent. But anyways...sounds like a bunch of lec 's are going to replace my Gavitas...soon....real soon. It makes so much sense. And really..the whole hps spectrum from the very beginning was meant for fruiting crops in a greenhouse. Where the blues of the sun was plenty and the reds needed supplement. Makes sense that people are seeing improved crop quality totally indoors with lec spectrum. We used hps all these years because thats what we were told first off. All we had second (besides mh). And thats what gave us plump buds. But the whole hps spectrum was never ideal for the only light source.
I would too but I like to keep my room sealed. Plus you have to if you're running c02. Or at least to best of your ability. Unless you like refilling tanks everyday.
I do use more co2 with the cold air intake in winter...but not by much. The intake louver opens up but sporadically. It drops the temp quick..then closes back up. I lose some co2 but its negligible at best. And worth it to not have the split running..throwing cash to the man every month.
Has anyone used one of these DEva setups yet?
Did you ever get a chance to record your harvest results??
I did. I got 4200 grams on 5 lights. Came out to 1.33 gpw.
I have all square wave ballast LEC's. When there is a black out/brown out/power failure in my neighborhood it takes the lights 20-30 minutes to comeback on line. I'm not sure if it's part of the design of the bulb, or the ballast, but LEC light will not strike when hot, thus the built in cool down period. I wasn't sure if you were aware of that, or not, so I thought it was worth mentioning.
It's the ballast. New technology to save the bulb. That's why the good ballasts simulate a sunrise so to slowly warm the bulb.
PM me bro.
