Oh, it will do for an extended periodThat’ll do. In a pinch.
Pray it doesn’t catch fire
3000K is closer to HPS than MH. No way are those lux numbers right. What meter are you using?Look at my homemade light!
$2 bathroom vanity bar from ReStore
$11 GROUNDED extension cord
$free piece of wood from the garage
$free chain I had laying around
$20 4-pack of 100w equivalent 3000k soft white. After extensive research these have a similar spectrum to a MH.
At 18” from the canopy I get 116,000 lux and 24” from canopy I get 102,000 lux. Since I already know around about what spectrum I have, im focusing on strength of light so im using Lux instead of PAR.
Not only do they work, but signs of light stress inspired me take the light measurements. Thats how I found out just how strong they really are
If you do something similar, make sure you get the spot lights. They act as their own “hood” and at 18” above the canopy, the DLI at canopy level increased by 2.3 as opposed to round 360° beam bulbs.
Im not going to claim it is a 400w equivalent without a professional luminosity test. But seeing light stress at 12” from canopy is enough to convince me they are strong enough

You need to knock a couple of zero's off your lux numbers. 11,600 & 10,200 . They'll do for short vegging but they'll get long and lanky without more intensity. Flowering will be a problem if you want any quality buds.....buds yes, some, but light and airy .Look at my homemade light!

Oh no you are most certainly correct! The actual draw is absolutely a mere 180 wattsHello!
Not trying to damper your excitement but most of those store bought LED bulbs are like 10-20w true draw. So you've built yourself an 80w LED plank! Well done and good on you for being resourceful :)
I would be a little reserved on those LUX numbers though. And you haven't even used a knife to cut off the outer "shell" of the bulb yet to expose the diodes...

Unless those are not LED lights and you can ignore everything I've said.
True, thanks for catching that. I was thinking of 5000k. The numbers are correct, of you would like you build one yourself to check them, I can give you more details and you may choose any light meter you like3000K is closer to HPS than MH.

If the lux was 106,000 are correct those plants would be dead.True, thanks for catching that. I was thinking of 5000k. The numbers are correct, of you would like you build one yourself to check them, I can give you more details and you may choose any light meter you like
LUX measurements are correct. These are for veg only. I actually have a four panel array from SunCo for bloom. As well as planning on achieving full 50+ DLI by moving the entire 6ct SOG out into the noon daylight everyday. As I run a productive nursery, im well aquainted with hardening off and moving plants according to light requirements.You need to knock a couple of zero's off your lux numbers. 11,600 & 10,200 .

Nice to see innovation and good luck, A guy here a while back @BigCube did similar and his came out pretty nice.
Correct! Which goes to explain why they were showing light stress in two days and have been moved to 24” awayIf the lux was 106,000 are correct those plants would be dead.
Have to remember, these are people lights for seeing that I am using, not “plant lights” produced by charlatans. To a greater or lesser extent they have to match any number they have on the box.

Sorry not to sway too far from topic here but - I'm kind of dealing with that at the moment. This guy I got from Hawaii grows weed on the mountain in Kauai and he knows his shit, don't get me wrong. But we're not in Hawaii, we are in Colorado - quite convincingly one of the hardest places on Earth to grow outdoor CannabisOh, it will do for an extended periodits properly wired, grounded, and insulated. I happen to know what I'm doing. I appreciate the concern though! Always nice to know people are willing to look out for a complete stranger that for all they know is an incompetent, ignorant dunce. I happen not to be, but I cant blame anyone for assuming
Ever used something like these?: Link: T8 LED Bulbs 4 FootLook at my homemade light!

Big learning curve when I moved from Mich to FlaSorry not to sway too far from topic here but - I'm kind of dealing with that at the moment.

I keep having to remind him that I have grown here for over 10 years and this is a WHOLE different ballgame.. If I had a nickel for every grower from Cali or Florida that came out here in the past 10 years to grow and failed, I'd be a millionaire.. It's ok though, he's learning! I do have to keep an eye on him, though
At any rate - cool homemade light I dig it!
