I agree growing with CFL / LED or whatever you like depends on how well you utilize the light that each can do .... Most systems have pros and cons , whether penetration , efficiency , heat , cost , etc.

But using some of these " beginner " lights only helps the grower polish up their skills.
I use Mars Hydro Systems because i dont have a dedicated room or space to upscale.
BUT ......

I just harvested a AUTO Papaya Gold ( grow journal ) under my Mars Hydro 600 with a G8 Bloom UFO. It never fails to give me good nugs and results because of how i position the light during flowering ( during week 5/7 i angle light ) and stay using 11/13 schedule. Weight is 488 grams.

I also agree light systems EVOLVE like the current COB builds - as i am building my own right now to see what it will produce.

You tilt your light to reduce its intensity?

Can I assume you circulate the air while the lights are on?

Nice stickies!:weed:

Expensive indeed. I've used CFL for a while too and was happy with the results. I went to the GalaxyHydro and felt like it was a step in the right direction but more like a lateral move than a big step up.
I can't really get the solid bud density out of CFL or blurple LED. The up front costs of a quality DIY LED light are easily justified by the added lighting efficiency and product weight.
Wow, :wall: I screwed up LOL. I did not realize how monsterous these 85 watt bulbs are. And I have 4 of them :dunce:

Opps.

On your COB build: I assume there is a COB below each fan. And each fan and light share the same power wire?

And the white sheet underneath is a piece of Orca? Thanks, :peace:

The white bord was only for photo. It is a metal frame / lattice :

5 cob build - 4) 3000k / 1)5000k center
Alpine 64 coolers with fans
It was a early build stage and is still being built.

My design is for a 3x3 tent.

It's louder than I thought. It's not bad when it's on lower speed but to keep my heat right it runs on full. I can't hear it but it's two walls bw me. You can hear it outside my house but it just sounds like bathroom fan or dehumidifier running. I'm going to look into some noise dampening ducting and fittings.

A lot of the sound from a fan comes from the vibration that migrates down the mounts. Hanging your fan from rubber straps or otherwise isolating the vibration helps the noise reduction a lot. You can also look into insulated ducting. That also seems to reduce the noise.

Rubber on every connection possible.

I think they make a baffle section you could place inline to quiet it too.
That's pretty fuckin clever with the aerated garbage can and lamp shade. Looks like it's not scrubbed though, the static pressure in that 1 1/2 inch pipe has to be a lot higher than if it was a 4 inch like that fan was probably designed for. Unless you have a lot of heat that you want to totally remove from the building, I don't exhaust outside. Just a scrub and exhaust back into the rest of the building with passive intakes.

Pushing the air through a filter makes it quieter on the exhaust side too as the filter acts as a muffler.

Thanks. I can run it on high, no problem. I'm only worried about sewer gases pushed into the building so I tested it on high for an hour and no bad stinky but I prefer low steady speed.

The pressure build up is in the chamber before the PVC and there is pressure lol. I have some fine tuning to do yet.

How much resistance through those filters produce?

You mean there is pressure in your lamp shade? Lol. The phresh filter I have is very low resistance but it's only flowing through 2 feet of 4 inch ducting. Easily, easily keeping my cabinet cool even on low speed.

I forget filter setups don't have far to travel. My 1.5" run is about 25' to the tie-in.

Ya, my lampshade stands at attention on full speed lol. I detached it from the wall, greatly reduced noise. The base is really sturdy fortunately.

I need to reduce some turbulence in there. Always something to do. Putting up orca - next.

:peace:
