What's up fellas? I've been interested in LEDs for a while now, scouring through threads, and really digging the results you're getting lately. I can normally find any info I need, within threads, without asking questions, but now I need help from the pros.
I'm helping a couple of friends design their gardens, and would like to make lights for both, using as much of the same components for both as possible. I'm thinking of going with flexible LED strips with 3000k-4000k, Samsung diodes, and worked my calculations off of this particular page :
*Well, I guess I can't post the direct link yet, but the strips are found on AliBaba, and supposedly have the Samsung LM561C diodes @ 60/M. I found them searching LM561C on the alibaba site, offered through the seller called "Brightest"
(Obviously, there are about a million options regarding both strips, and sellers, and I haven't yet dealt with AliBaba, so any guidance there is also appreciated...especially if I don't have to deal with them, and can find someone comparable closer)
Now, one of these gardens will be a horizontal, over a 4x4 table with about 5ft of headroom, and the other is for a vert grow in a 4x4 tent. I have ideas for both, but the vert fixture is what I'm more concerned about figuring out the correct numbers for.
I guess the short question is: What are the minimum and maximum distances from vegetation should these be with acceptable PPFD?
For the horizontal garden, I don't want to be too close, and for the vert tent, I wanna make sure I'm close enough.
So, here's my idea for the vert fixture: Flexible LED strips wrapped around 6" duct, 24" long, with either a Vornado type fan under the fixture, blowing up, or a 6" duct fan installed at the top, sucking out.
Below is a diagram and my calculations, as far as I could figure. This is where I need your help deciding if the numbers add up, and I'm onto something, or if I'm waaay off. I'm shooting for around 400w power on each fixture if that would suffice, but the vert can afford to go to maybe 800w, if needed. The diodes should be about 21" from the walls, and less to the leaves, when the fixture is built.
If this seems doable to you guys, let me know how many of which drivers you would recommend, etc, and I'll build it asap, and see how well it works.
Any help, questions, or critiques are welcome and greatly appreciated!
