I live in the land of Mordor where there is prohibition and literally only grow for myself, and I just started anyway. I appreciate your concern! I also spend way too much money on fly fishing trips.

Another thing, I'm too scared to sell, so I end up giving it away. I'm the fucking weed fairy.

Bob, I saw the different spread options, what's your opinion? I would think the more directional options for a smaller space, but I do not know.

Sorry but you guys are on the wrong path and need to educate yourselves more. These highbay lights are what some scam companies are passing off as grow lights and not what they were designed for,parking your car. For $2000 you could build a 64% efficient killer light for a 4x4 or buy a 40% range efficient commercial built grow light.

that cree highbay looks like it will make an A Okay veg light.
bit expensive for a veg light and still need a high ceiling to get the spread needed.

Light decreases in intensity as the square of distance. That makes for round growing areas.

I think round grow spaces are actually quite logical. What shape is an LED? It isn't square.

you guys are idiots, look around the world at any modern day agriculture, including small medical growers. EVERYBODY grows in rows and rectangles indoor or outdoor. There are certain logistics to accommodate humans and machines to maintain the plants, irrigation lines, walkways, machine access.

Have you ever seen a circular grow tent?

Inverse square law has very little to do with a round growing space, it relates primarily to the spread of the light as distance increases.

The only use for a round growing area is if you were growing a single plant with a single light. Incredibly inefficient AND ineffective way of growing.

I am not going to buy one, I'm making an order for 6 CXB3590s with lenses and holders with Jerry literally right now.

Actually, have you ever heard of radial sprinklers? Look on a map, many agricultural plots are quite circular. Though I agree with you about indoors, on a large scale it works and is quite common outdoors

I used to work in fields with center pivot irrigation, alfalfa ...... Yes the irrigation is circular, but the plants are still planted in rows.

I'm an idiot because I recognize and work within the limitations of accepted physical principles?

Guilty, as charged.

no your an idiot because you ignore the larger physical properties of the whole grrw space versus the physical properties of only one component of the grow space.

trees versus forests

And for a genius you sure leap to a lot of conclusions...

I suppose it would be wisest to just buy the cobs and make your own mounting. No commercial lamp is going to evenly cover a 3x3 or 4x4 square. Besides, it's more fun and satisfying to make your own stuff. I wouldn't buy commercial heat sinks though. They look overpriced. It's just aluminum. Just tig weld fins on a flat sheet yourself. Just rent a tig welder for a day or whatever. There may be something else that would work anyway. Just needs to be high surface area aluminum. Actually, you could probably use a part for an air conditioner.

wow denial you still have not come up with a real reason that we should shape our grow space to match a round high bay light. Your just like Hilary Clinton when she said "Why does it matter?"

All you have to do to that light is this.

I have been trying to dial in my room for a while and just have had bad luck these last 3 runs, so I can't give true #s with this light, but I have it over a 3'x3' tray with a 40"x40" canopy. I have been running full strength for the last 3 runs and my Blue Lab truchean PPM stick has been reading around 800 PPMs. Yesterday I tested some of my tap water and it is at 700 PPMs, so I have been feeding them at over 2000 PPMs. For now I am using bottled water. My best yield with this light at over 2000 PPM was .55 grams per watt. So they do work, just I don't have a problem free run with them yet.

I have the answer for a heatsink, hot water baseboard heater pipe. It's called fin tube. I don't know the price. The steel pipe kind probably aren't too costly. Copper would be more expensive. They look like they should actually conduct heat away better than the thick heatsinks people are using now, more surface area. Looks like just the right width for cobs. Unfortunately, it's ridiculously costly. Guess you'd have to find some used. Actually, just use thick aluminum foil and fold it into a bunch of fins. That's your cheapest bet.
