Lights look like they use some new tech, so you won't find any finished grows with them I imagine. The safer bet for $250 would be a blackstar '240w' (really 140w) and for that space you wouldn't need any other lighting for veg or flower.

Its a full spectrum LED panel if that matters, I haven't seen any other company go for more than twelve. And they're the only company I know of that goes the full 12 with all 3w diodes AND also uses that tech that makes its so only 1 LED can go out at a time (GLH also only one I know that has a...

Yeah, from now on I will always do seedlings for one week under CFL (though I have an LED for main light). Much easier that using all that electricity and making all that heat and having to figure out what height to keep it at,

Sorry I think I am confusing people. I don't have a '240w' Blackstar I have a 395w Spectra from growledhydro. I would be worried about keeping it in a closet that people would be around as it is as loud as a computer (not a crazy one full of fans for gaming but not as silent as my nice gaming...

I have a GLH not a blackstar, my GLH has 6 fans that run on 3w I believe and its comparable to a loud Xbox 360 or an average gaming computer (one that isn't super quiet or exactly loud) "There is no more efficient LED than the High-Intensity 1W 10mm Diode" See that is where they get people I...

It sounds like that light uses some new tech, so you could try it out for everyones benefit. If you are not willing to risk your money, you could go for a blackstar '240w' (even though its really 140w) as its the most proven unit I know for less than $300 (you can get it on sale for $250 once in...

Does anyone have a list building up around here of strains that do not seem to do well with 12/12 from seed?

If you think GLH is expensive at just under $3 per watt you should see some other companies. I think the penetrator series of LED panels only use 1w diodes and they want just over $5 per watt. That said, the cheapest that is worth it that I've seen would be Blackstar 3w diode panelsthat are...

I like your math, but think you made a poor choice for your LED comparison as that penetration pro wants over $5 per watt when everyone else is charging less than $3 per watt and sell more technologically advanced panels (blackstar 3w is like $2 per watt and GLH 3w is just under $3).

Ahh smart man. A lot of LED lovers seem to do that now, they kept their HID stuff for winter and/night grows because the LED runs too cool :P For me and for now its just my 395w LED and my 4x24w CFL pc Grow box for seedlings, (gaming computer can keep the room warm when the LED can't :P)

Just think, $1500 on a 600 1w LED panel. If one LED dies you could potentially lose hundreds of LEDs and be completely out if you have to turn it in for repairs. Where as with several other companies you could wait longer before having to send it in for a replacement (and get a longer warranty)...

When I did it that way the fastest seeds took about 14 hours, but most take 24 hours or more, I've had some that I thought were dead after a 3-4 days of this but they popped after a several days in soil. You are using warm water/ water and a heating pad right?

I suppose one downside to LED is that you can't do much about the noise their cooling fans make, its not like with HPS where you can put the fans wherever you want.

What I heard about that was he and others would talk of their bad experiences with certain LED companies that started becoming Sponsors and so someone got banned and then a bunch of people left. I don't think Irish is on anyone's pay roll, I've been following him and his buddies and talking with...

I doubt its worth it if they're still using 1w diode. While 1w is the best as far as efficiency when converting power to useable plant light, but they do not complete with 2 or 3w diodes as far as penetration (600 1w diode panel <<< 600 3w diode panel). If they were using all 3w diodes I'd...

I thought the idea was that you were attempting to replace the HPS entirely? Or just enough that you don't need A/C the entire day? I think you underestimate how cool they will be :P My 395w (your two new units together will only use about 280w) makes less heat than a 100w HPS

How I've head it explained was that basically they are reliably tested/pylsed of a max wattage like 1w or 2w or 3w, and depending on the manufacturer of the LED and the wavelength you can run it safely at a certain wattage with the fans and heat sink used for cooling. It would seem 3w were...

I made a super soil mix of fox farm ocean forest, light warrior, and their original planting mix plus a bag of black gold. Then I mixed in some Mykos and Azos, and topped it off with a small amount of happy frog Tomato and Vegetable stuff. Oh yeah also some perlite and dolomite lime. I imagine...

Blackstar units tend to run on only 55% the wattage their namesake would imply, so your friends blackstar is about 330w of LED compared to your 600w HPS (and in my opinion not the best 330w of LED there is). You can bet though he would whoop you good if he had 600w of actual 3w LED blackstar...

Mykos is with a K :P I love the stuff too, the tomato plant I gave mykos to is as big as the other 3 tomato plants put together and they've all been planted since Mothers Day. Sorry if I made blackstar sound incapable, I give them a bit of a hard time for misleading on wattage, but next to GLH I...
