Using a 3x6 dryer telescoping dryer vent. Took it apart. Cut out a 6x18 and put a 6x18 heatsink with a GrowGreen 200w mixed spectrum 5000k and 3500k with 384 Samsung LM561C diodes using a hlg-185h-c1050b driver active cooling attached to a 4" inline exhaust fan removing heat from the grow area.

I know I started a thread on row room automation, but I thought it would be placed here in the design area. I have been looking into various automation systems. I have looked into led controllers, hydrop0nic controllers, and home automation. I decided on a complete approach, control Air...

I have been looking on the internet for various automation projects. I found this one and believe it may be of some benefit to the community. It is called Billies Hydroponic Controller. There are links in the arduino forum with the code and the code has a list of parts. There are also a...

Here is a short 5 minute video on UV lighting. enjoy

I participate at other sites and I love tinkering with electronics. I have been following a discussion on 3 in 1 Dimming capabilities and what it is useful for. For me, I found out how to use an arduino device; Storm, Typhon, or arduino uno; to dim led fixtures identical to the ones we DIY here...

Considering combining 3500K and 5000K on one fixture for a combined veg and bloom light, running both colors through the entire growth phase. what are your thoughts?

A member at another location found this passive heat sink that will utilize passive cooling from 50w-80w without any fans cost less than $10/each . ->https://www.cdiweb.com/ProductDetail/MODULEDXTRA9980B-mechatronix/574061/#.VvEZvzHz8gv

This is my 8 CXB3590, 36v, 3500K, CD bin, w/ 2 Meanwell hlg-185h-C1400 drivers with a meanwell 12/12 LDD driver for the two fans. It also has far red but I am waiting for the driver lpc-35-700. peace

Here is the new DIY 200W fixture running four CXA359072v with a mean well C700B driver driving each CoB at 49W each. Each CoB can run up to 135W, but efficiency lies here at 49W. peace

Finished a DIY 4 CXA3590 200W LED. peace
