Super Lemon Haze on the left Jack Herer on the right Got the airflow tuned (along with a window unit in the bedroom to keep it mid 70s) so that I can run both COB units at full power and hold temp's at 81-82f. Can't wait to run it in the winter and see how she fares =).

Close to achieving its final form. Mounted to 18ga aluminum stud. Nice n simple. Scrog set to 3 inches. Thinking about changing to 2.5 inches next day off. Haven't decided yet.

I understand its a mega ohm. I guess I just don't quite understand how they work. I figured a 1 mega would be able to make it more dim =).

And Gallileo was once alone... faaaar less than 3%, when he said the earth was round and revolved around the sun. Look how that went for him.

Carbon filter system is done. After a couple of days piddling with the filter box, I had to go with a DIY filter cartridge with some strips of 1.25" wide wood to make about a VHS casette size filter insert with a screen on the front and back to hold a couple pounds of activated carbon pellets...

It's this one here https://www.radioshack.com/products/radioshack-1m-ohm-linear-taper-potentiometer I'm about to put together another cob fixture got sit next to the one I have going now. I'm going to use the info on the thread linked above and put them both through a common 50k and a resistor...

I got a 1000k ohm pot from radio shack. Works ok, but it doesn't start dimming until the knob gets past about the half way mark down and only dims to about 50%.

Yea, and that's a bit lower than what I was aiming for in the beginning (mid 400's) but I figured these 2 fixtures would be a good starting point and go from there. I have about 40 3w star LED's of various blues and red wavelengths that I plan in to work in as well over the moderate future.

The inside footprint is about 2.5 ft deep, 4 ft or so wide and just under 4 ft tall. There's a shelf in the back that goes behind the veg box to hold the pots containing the flowering ones that keeps them hidden nested nicely as not to sacrifice the precious verticle space. Almost done, just...

Picked up fella from amazon. Freed up about a half a foot in height in the bottom box. My old light fixture sat atop the 4 angle brackets that I haven't removed yet. http://i.imgur.com/dYCARht.jpg Ordered the supplies to make another COB unit just like the one pictured before in the thread...

On the topic of hermies, I've often wondered - how do SJW minded libskee growers reconcile the idea of a hermaphrodite being a "bad thing" that needs to be culled from the herd and having them show up is an indication of problems? It must be quite the internal conflict.

Almost 'done' with this this project. I use the term loosely because are we ever done? The closed unit. Not quite light-tight, but it's getting there. Behind the doors, a removable (a few bolts holds it to 1.25" steel 'angle iron' frame) piece of plywood seals the top unit from...

Thanks. I've spent quite a bit of time and money with it. I have a bit to do even still. As of right now the plan is in the end it's going to house a flat screen TV. Mostly all funded my Amazon MTURK work in my spare time =).

While contemplating how to arrange my filter, I had this idea that I started today, doing away with the tube and putting the vent intake about as high in the unit as I could get it and freed up a LOT of room for vertical light movement. I figure I'll make a 'fill hole' plug on the top of the...

Ok, I got my first fixture strung up. Worked out a handy little pulley system for it, maybe before long I'll put a crank instead of the loop n hook method i've currently got jimmied up in there =).

Planned parenthood has nothing to do with 'women's rights". Planned parenthood is all about eugenics. Just a LITTLE bit of prodding around the googlesphere will show its founder a racist eugenecist. That's why you only see these places in or near the ghettos.

Cobs are all mounted to heatsinks and wired up, sitting in a box waiting for me to get some angle aluminum or some sort of framing material to mount them in the air. I haven't had a chance to mess with the exhaust. I'm thinking of just taking some tubing and making a soft curve upwards out of...

I found some class 12.9 steel screws at fastenal. Wish I would have started with that. I've got the cobs assembled and ready to get the framing and suspending hardware this weekend and I'll get some shots of all that when it's done.

Well I have everything to get a cob fixture burning when the time comes. Tho the heatsinks I got only came with unthreaded m3 size holes and the only m3 screws I can find in town are half inch long zinc screws and I can't find an m3 .5 tap sold by itself either. Apparently the penalty for...

Right on thanks for the infos.
