New addition to the lighting. I had some 3070 COBs covering one end of the room while waiting for this one to come in. The bar hanging about a foot higher than the rest (over the Panama's) and about a foot wider. It's running 4x Citi 1212 COBs at 1400ma for a total of 200w, dimmable. This gives me a total of 800w covering as much as 3.5'x8' properly at ~30w/sq./ft., current run is pretty close to that now. Having it at the back and being wider gives me full coverage across the 4ft. which I can use when I have an odd plant, like the one Panama I have in the tent with the male, it'll get moved into here once it's been pollinated.

damn man,such a clean grow.are you running strictly cobs now?(sorry if youve answered this before)

Day 33 and Day 26 last night. Zoom on the 6x 3gal's and Panama's under the Citi's. Nice stacking going on all around, really liking the look of the Panama back-right, strong lemon smell coming off it now. Couldn't get a thumbnail to post the full pic of the Panama's, not sure if it's the site but it's happening more and more lately...

Hey thanks, yes just running COBs now. Switched to them a few runs back and there's non turning back. The heat alone is worthwhile, with 2x 315's (CMH) in there I'd have a hell of a time trying to stay under 82F. Now I'm running 800w of COBs at the worst time of year for me as in between seasons my HVAC doesn't kick in, and still averaging 80F.

that is awesome to hear.the heat was what i was curious about.im thinking about researching all summer to set up an indoor by fall/winter.the space is real tight. 2'w x 5h x 7' L.

Thanks, that room is 4'W x 9.5L x7.5'H, running 800w @1400ma and easily managed with 4" incoming and exhaust inline fans to control temps and humidity.

Your room would lend itself well to COBs (Citizen, Cree, Bridgelux Vero's), don't think the brand matters much as long as you stick to any of the above that have been proven out in the field.

Only thing you may want to consider is that there is heat, COBs still produce heat, just less than bulb-style lights like hps or CMH. So you'll want to make sure you have decent exhaust and cooler air coming into the space with only 5' height. The COBs will allow for taller plants as the overhead in height is less and you can get them closer to the lights than bulb-style lighting.

thanks so much,GroErr, nice info.ive written down the cob info.yeah,the width concerns me the most.its going to be a bit of a carpentry nightmare(going to have to figure out sliding solid doors,from plywood)my plan is to have a veg area underneath,flower up top.there is actually a window in the space.i have two questions if i may? 1.) would it kill the effeciency of the inline fan in the lower veg area ,if it 90's up and tees with the upper fan exhausted out the window?
2.) is the inlet too close to the actual grow area(within inches)say during winter? thats going to be some immediate cold air.maybe i could put that inlet fan on a timer?
thanks for any info.your room cleanliness and forethought is the model im going for.

Yeah the sliding door's sound like a great option, some more work but will give you better access and more space.

Any disruption in the flow will increase the work on the inline, you may want to consider a 6" with a variable controller to allow for any 90's or T's in the vents. You could time it or trigger it with a thermostat controller like this one http://www.homehardware.ca/en/rec/index.htm/Heating-Ventilation-Cooling-Home-Comfort/Heating/Furnace-Parts-Acc/Accessories/Booster-Fan-Thermostat/_/N-2pqfZ67l/Ne-67n/Ntk-All_EN/R-I5532248?Ntt=thermostat Just be careful brining in any outside air, you'll need a filter, even if it's just a simple/fine screen to keep bugs out. A carbon filter on it would be even better but will restrict your flow a bit too. Consider a T inside the room to deflect the cold air and spread it so it's not coming directly into the plants. The room is too small to consider putting an AC unit in there so you'll have to work around that with incoming cooler air. AC's generate heat inside a room so not a good option in a small space like that.

im not sure if i'll be running during the summer...maybe the veg.in that part of the house in the winter it sits at around 62-63°f.ill just have to try and see what happens.i know heat really increases when enclosing an area and adding a light.any light.hadnt thought about a larger fan,makes sense.so youd use a carbon filter on the intake as well?

@GroErr how long is it taking to flower your quickest finishing plant? Seems like u have some quick finishers from what i've seen. Plants arr looking fantastic as usual!

If the area around the room is sitting at 63F that should do it in the winter, the air coming into my room summer or winter is 68-70F and does the trick by just adjusting my variable controller on the intake inline fan. The catch will be the temps outside the room in the summer, if you think it'll be under 70F that may do it. Remember you're pulling in cooler air and exhausting hot air, the combo is what controls your temps. Problem with outside air is other things like PM coming in through the vent if it's not setup with a carbon filter. My incoming air is pulled in through my HVAC so I don't need to filter it as it's filtered through my HVAC. But at one point when I first started indoor I was pulling in outside air. Once I hooked into my HVAC I stopped brining in outside air directly into the room.

Cheers @green217, difficult answer on that one so takes some explaining. It's been variable since I switched to the COBs as I've been trying different setups. Changes have included low wattage/sq./ft. initially as low as 22w/sq. ft. at 12.5/11.5 for the light cycle (very slow finish, added up to 2 weeks in finish times, but nice yield). Then I increased to 30w/sq. ft. and ran at 12/12 which finished faster by at least a week, but still slower than under CMH. This round I went with 11.5/12.5 for the light cycle to see if I can bring it down a bit again. Next round I'm trying 11/13 which I think in combo with 30w/sq./ft. will bring them down further and likely where I'll land if I don't see much loss in yields. I've been keeping at least a couple of strains/phenos (clones) the same all along so I can judge any differences in yields and finish times.

So a lot of variables but getting closer to what I was getting under CMH finish times. Still about a week more than CMH but last round I could have pulled my Blue Pyramid (running at 12/12 that round) which is the earliest at around 52 days, let it go an extra few days on purpose and pulled it at 56.

The way things are going this round I'm expecting to be able to pull the Blue Pyramid around the 52 day mark, and the Blue Harley around 56-58 days which I'd be happy with if yields hold up. Not seeing any reduction in yield so far ;)

g'day Gro,
When flipping from veg to flower, do u flip to 12/12 after 6 hours of darkness or after 24 hours of darkness:confused:
:peace:VG:eyesmoke:

yeah there is a lot of variables involved to say the least. But being able to chop under 60 days is still pretty nice

Good day to you, most of the time I don't transition them at all. I just wait for lights on in the flower room and throw them in straight from the veg tent. On my schedules that means they get about 3 hours of light in the veg tent + 12 (11.5 right now) in the flower room the first night. Only other thing I've done the odd time is pre-stretched them by turning my veg lights down to 14/10 which induces the stretch and gets them pre-flowering. I've done that the odd time if I'm waiting for the flower room and the plants are ready to flower to get them going and get a bit ahead of the game. It's been a while since I've done that, I did it initially to see if they would start transitioning into stretch and flowering at 14/10 and most strains will. More typical is the first scenario.

For sure, keeping some clones in there gives me the constant so I can see what if any changes show up when I'm changing the environment. Definitely nice to get a couple of earlier strains in there, that Blue Harley got some of the earlier finish trait from the mother (Harlequin) which I'd finished in as little as 49 days under CMH but produces almost twice as much per gallon of soil :)
