And sound-absorbing tile, acoustical ceilings, double walls with an air-gap in between and a sound-absorbing liner (rubber mat?) at the frame contact-points never hurts. Even laying rigid Styrofoam insulation on the floor as a base might give a measurable result.
this is good stuff for when I move and start the wheel back up. . . If it was insulated and in a basement, I'm sure the noise would not be a problem.
I know a simple, low-heat,
and even quieter solution.
Vertical bare HID bulb or with 360-degree cool-tube if one prefers. It runs way cooler than an HID bulb in a hood, and the direct light is far more intense. I was surprised at how far away the plants need to be from a bare bulb in order to prevent stress.
Bare bulbs already run cool because of unimpeded radiation, and if you run a circulation fan pointed straight up at the bulb from below, as I like to do anyways, temps are incredibly low.
All you need is a cordset and socket to check it out.
and some welding goggles
hmmm, well I don't really see how the orientation of the bulb would effect heat radiation, horizontal bulb in cool tube vs. vertical. . . definitely a distribution advantage in a radial garden. I guess hot air rises, so that could send the heat up and out instead of over and out. might be more efficient.
i do have to argue the quieter statement. . .
maybe as quiet but not quieter. . . lol, the water cool is literally silent. can't get much quieter than that. and you'd be amazed at how cool it is. . . you could literally lick the tube and it wouldn't be hot. try that with a bare bulb
hey wheelo my journal is at green passion my screen name is T&T Dynamite and the journal is called decidedly different roto-gro
I hope ya get a chance to take a peek at it.
yeah now that you said that, i remember checking it out when you first came here. . . if you shoot me a pm with a link, i'll def check up on you from time to time. . . but i have no desire to sign up for another site. this is my grow home.
Niice loookin bud WOF. Bud looks great
Kudos to ya for silencing the E/G too, i bedroom grow so I kno how annoying the sound can be sometimes. Good job bro
so quiet now. silence is golden bro. and the budz aren't that huge, but are fantastic quality. . . a bit stronger than usual, and I think it's due to the Bud Factor X, which I used a 1/4 strength. (2ml/gal)
How much light do you think you are losing as it passes through 2 layers of plastic/glass and the water in between? I'd be curious to see a light meter held 18 inches away from the bulb in the water cooled reflector as well as the bare bulb or bulb behind a single pane of glass.
well, I don't have a light meter, so I can't give you personal empirical evidence on how much is getting through, but I can tell you what the manufacturer says. . . and we all know that they can't embellish at all. lol.

How effective is it?
The Fresca Sol removes 93% of the radiant heat emitted from the lamp, leaving your flowers and plants happier. Traveling through the glass and water you lose 8% of your lumens, but compared to an air cooled fixture that hangs above 18” to 24” from the tops of your flowers, the Fresca Sol can be put 6” from the top of the flowers. This results in 9 to 16 times more candle light actually hitting your plants. As far as the spectrums, they are all increased by 5%! Yes, believe it or not, you gain 5% more blues, and 5% more reds!"
it obviously cant increase the amount of light. . . i think what they mean here is relative to output. . . removing the IR boosts the
RELATIVE amount of light in each spectrum
"
Am I losing any of my lumens by using water?
We have had third party testing completed on the Fresca Sol. We have the results posted on our website. You do lose a very small percentage (8%) of your lumens. However, because you are able to lower your lights very close to the canopy, you are gaining over 9 times the amount of actual light getting to the plants."
. . . now, I'm not gonna run it @ 6". first I think that's too close regardless of how cool it is, second I have a mover, and need to get coverage out to the sides while it moves, third, even losing 8% of 140,000 leaves me with 128,800 lumens. . . if i moved the bulb a couple inches closer (but not a ridiculous 6") that would esily make up for the loss, but honestly I don't care about such a small loss. . .
I wonder what a single pane of glass reduces the output by. that I have no idea about. My friend mentioned getting a light meter soon, if he does, I'll have him bring it over and do some tests.
Sort of a pain, 2 gallons of wet hydroton and root mass gets a little heavy.
