DIY: CFL "Panel" - safely!

Have seen a lot of pics here with wiring/extension chords and just downright unsafe environments for CFL setups.

Thought I'd post this to show what you can do, easily, cheaply, safely if you're planning to grow with CFL's. It's not the best I've seen by far but it easy/cheap, effective and safe.

I use LED's for growing but I do use CFL's for my clone tent and plan to use these for additional side-lighting when vegging (6500k) and flowering (2700k).

With Y adapters they can fit 12 CFL's per "panel" (I call it the GP-1000 - or Getto Panel 1000). It would be difficult if not impossible to put 12 CFL's of any size and draw even close to 15A so no worries on safety.

  • Find a piece of 1/2" plywood, my clone tent is 24"x24", so I made the wood panels 11"x19" to fit 2 in the tent and allow for air movement ($0) had it in the garage
  • 2x bathroom light fixtures with 3 sockets each at Lowes, $12/each (they have 4 and I think 5 socket fixtures for a little more if you have the room)
  • 1x flush mount electrical box w/cover (safety!) $1.50
  • 1x computer power cable w/ground (I have about 10 of them, you can buy a similar chord at any hardware store for $2-$3)
  • 2x L brackets $1.50 for both (I use these when I want/need to use them as side lighting)
  • 6x Y adapters, ebay, $1.25/each (I bought 2x 10 packs for $24 delivered)
  • 4x Hanging hooks w/screw on back-side $1.00 for 10 pcs at the dollar store
  • 1x Wiring box clamp (I had some) $.50?
  • 3x Plastic wiring screw connectors (I had some) $.50?

Total Cost per "panel", $30-$35, not burning your grow and house down… priceless as they say...

Step by step assembly: (Disclaimer: if you can't follow this, buy something, don't zap yourself if you don't know what you're doing)


  • Remove the front face from the bathroom fixtures to get at the cabling (pull up on socket covers, then remove one screw on side of each fixture, pull casing up)
  • Drill a hole in the back of the wood panel to pass the cabling from the bathroom fixtures through to the back and allow the fixture to lay flat on the plywood. (drill the hole as close to the centre as possible as this will balance the panel)
  • Mount the two bathroom fixtures flat on the plywood with 1/2" long wood-screws, passing the cables through the pre-drilled hole
  • Mount the wiring box flush to back of panel, punch out one hole to feed fixture wiring through, one hole to feed the power cable through
  • Connect the wiring from both fixtures together, cut the female end of the computer power cable to get at the wires and strip 1/2" off each wire
  • Connect the joined fixture wiring/cables to the computer power cable, inside the electrical box (black-black, white-white, green-ground), clamp cabling in, screw box into plywood, place cover on the box.
  • Screw your hanging hooks into the back side, one on each corner, you'll use these to hang them
  • Flip it around, screw the front face plates back on to the fixtures, push the socket face plates back on
  • Optional: Install L brackets as you see fit for your needs. I use them (they bend easily) to either mount as side lighting, or they can support the panel on the floor for side-lighting


Voila, you've just built yourself a GP-1000 :)
Here's one with only 6 lights on, like I mentioned above, add 6 Y adapters and you can have up to 12 CFL's on it…
3 of these, one on top, 1 on each side, a couple of clamp-on's and you'll reduce your cabling/extension chord mess, and sleep better at night…

that looks great. Thanks for the info
 
Man looks great definitely going to try and mock up my own. But I like keeping my cfls super close tho, allowing for better shaping. They work just fine while hanging above?

You can do a lot of things for side lighting, with the brackets you can sit it or mount it for side-lighting and get it as close as you want. You can also use those clamps you've likely seen around here but when you start using only those (clamps) you end up with an octopus of extension chords/power bars. 3 of these, one on top, one on each side give you a lot of wattage and by adjusting the brackets you can get them close. Just an idea, even if you use one on top then a couple of clamps for side lighting it reduces your "octopus" and makes it a bit safer...
 
I have 2 chambers so i build one for a top light and have 1 side light so far, i also have a square tapered 3.5 gal bucket with pvc out each corner so i can clip on those clamps in the bottom chamber that allows me to shape my plant. but soon ill have a cab with ups/mh and maybe some side cfls. i Hate the amount of cords i mess with now tho..
I love how cfls grow!!! :weed:

Yeah it's amazing how quick you can end up with a mess of wires… in an enclosed space, high humidity, and watering plants, a few too many tokes and ouch #@$%

I am impressed with CFL's too, just grew out couple of clones with them, two weeks and they were like this (pic), switched to my 300W LED now and they're happy girls :) Mainly using them for starting clones/seedlings, then switch to LED, much more light and faster veg cycle…

What do you recon about using cheap desk lamps for CFL'S?

Thanks in advance :)

Sure you could, pretty sure I've seen some in here. If you have some lying around they could be maguivered to mount them. Only thing with those is you have a power source for every lamp, so if you're using a few it can become quite a tangle of power chords. They don't draw much in amperage or wattage, you could tie 2-3 of them together to one power chord to reduce the octopus factor That's where these bathroom fixtures come in handy, less of a mess. I don't use CFL's anymore for anything other than adding heat when I need it (clones, winter). Efficiency-wise as LED bulbs have come down, it may make more sense to use E27 base LED bulbs, they run cooler in addition to being more efficient. Cheers.

Thanks a million for the help man ill have to look into LED for the next time round... I've got friends using LED for Aquariums too! Works well for coral and coral need's bitch tons of light. They look very attractive to anyone with the pocket for it- $$

i plan on useing some CFLS to start a few seeds in march of next year and then set them outdoors here in kentucky around 30th of april or 1st week in may..so just regular computer desk lamps i can put in front of about 15 seedlings and they will come up out the ground? i have pretty good weather here the climate is subtropical and i have always germ the seeds around middle of april and then set them out 10th or 15th of may but im wanting to try something new and get them a bit taller u think that will work?

They'll work fine for seedlings or clones, you can use pretty well anything at first, they don't need much light for the first couple of weeks while they establish a root system. Last round of clones I ran some 40w LED tubes to root them for the first couple of weeks. Beyond 3 weeks though you'd need to get them in the ground outdoor or provide some additional lighting, you can just add some more cfl's for the last couple of weeks before throwing them outdoor to get them a little bigger. There are folks doing complete small cabinet grows in here with only CFL's right through the cycle. I wouldn't use them for flowering but for your purpose they'll do fine.

sweet ya i can set them out around april 20th-25th bc frost is over by then for us..this year when i sit them out they was only like 2 or 3 inches tall..i want them to be around 6 or 7 inches tall when i take them to the hill..sweet thanks for the info!! makes sense they dont need much since they are working to develop a root system

Yeah, their focus is on roots early on so lighting doesn't play a huge role. I've used Fluoro's,T5's, CFL's for my outdoor clones over the years, you just need something to get them well rooted, temps and higher humidity are more important factors than lighting early on. Gives you a near perfect success rate outdoor if you have a good root system starting off.
