LED grow lights... input please.

Yes I do. I also stated that a few posts ago

Do you have a husband named Rory. I say this because because of your Real name from the other forum and I think I might know you.

Nope, I'm a lesbian. I have a wife though :thumbsup:

Ha Ha, OK, They are from Medford Oregon but I had to ask, been trying to get in touch with them for a few years now with no luck.

I am new to the forum, and extremely interested in growing with LEDs. I have never cultivated MJ, but plan to grow other things. I am pretty good with electronics and understanding basic electrical theory, and plan to build my own light panel using reliable parts from the net.

My question is, how much is enough?? Personally, for a small home operation, i think a 600w HPS is overkill and a waste of electricity since most of the energy is converted into both unusable spectrum of light and heat.

Leds sound like the right idea given plants only need certain spectrums of light to grow and be healthy.

How much LED power do you really need for a 3-5 plant setup??

I'm using 300 watts of LED light for a grow about that size through flowering. This is my second grow using them and they do work well.
Just make that the individual emmiteers are strong enough. 3 and 5 watts each are preferable.

M.P.

thanks for link to the ledgrowlights. I posted this very question on another topic I started but nobody replied as of yet. I'm guessing these can get expensive or maybee a bit difficult for first timers but there seems to be very good for air flow and heat. Can someone tell me about how many would be needed in a stealth cabinet or closet size grow box?

Can someone tell me about how many would be needed in a stealth cabinet or closet size grow box?

To me, a stealth cab and a closet are two way different sizes. I would say:

Using good parts and efficient drivers, 50 watts of LEDs will match 100 watts of CFL, fluoro, or HID.

Costs about $2/watt for the LEDs plus $1/watt for the drivers.

So, for $180 you can build a 60 watt LED light that'll match 120 watts of something else. (A 90-watt UFO will NOT replace a 400w.HPS. That's a sales pitch. 200 watts of high-end emitters and drivers, though....no problem.)

Not really cost-effective (yet) unless:

a) heat is a big problem
b) electricity's real expensive, or
c) maximum stealth (no electrical or thermal footprint) is critical.

I'm probably gonna put together a DIY tutorial if anybody's interested in building their own light. Let me know, Hermie.
