LED Ahoy!

[rattlingdags]

Just make sure you get some panels with more blue in them. As you see, it definitely makes a huge difference. The plants in the middle primarily under HPS were nowhere near as frosty as the plants mostly under LED.

Thats a handy tip thanks. Could I make do by adding some 6500K fluro's? Hubby brought some home recently and I had my eye on a couple for the bloomers. Would love to get some more LED's but finances don't allow it just yet.

There's still the krusty/DWC update, but that stuff is going to be hash. pH swings like mad and heat issues from poorly-ventilated spaces caused that to be a complete cockup. The gear: 1 new prototype 50w quad-band+4500K white LED, combo 120/90 degrees. 1 Current-gen 50w tri-band solar-insolation spec LED, fully 120 degrees. 1 current-gen 120w tri-band solar-insolation spec LED, fully 120 degrees. The 120w gets my two largest mothers, Rating: 5

Figured I'd toss in my LED flowering pic,.... single plant SCROG under 120w LED. (no HPS) Not sure how long in as I forgot to wright down the date, but it's less than half way there! imp:

looking good theres been more and more hype about LEDs pros and cons but hey they look nice so whatever works for you, plus the electric bill isnt as bad as some of us, lol well ill keep up on how they do ferther along in flowering i havent seen a plant go all the way threw on leds and am anxious to c how they do..love from the glove...420...

Read my entire LED Ahoy thread, check out stra8outtaweed's LED Grow Show, and Weezard's LED grows. Plenty of 'em done from start to finish.

That first plant - wow she's a thing of beauty. They all look great
How long did you veg them for? We're thinking of trying to make some extra height to enable us to veg for maybe a month (instead of just 2 weeks) and I'm wondering how well my led's would penetrate the leafy indica foliage if I let them grow out longer?

The veg period was a month, as these were all from seed and needed to mature. Notice the Smile, which towered above everything else, going so far as to grow above the LEDs and HPS.

people think LEDs don't penetrate. You can't really see it but if you took a quantum meter below your canopy you'd be able to know how well it is penetrating.

Considering those are 1w diodes in the panels, I'd say they penetrate pretty well.

Really, really nice, khyber...mad props! I'm looking forward to seeing the yield.

If I ever go to lights I'm going LED. Thanks...and keep up the good work!

Yield total was just shy of two pounds of bud. I'm going to take all of the trim and let my O.Chem. guy run multiple extracts on the material. He can get about 98% of everything right out of the plant in multiple different grades from green and gold oils to dark tars. Probably looking at about another half pound of that possibly given we've got just over half a pound of trim.

Yep, been a while. Been working in my secret garden and never take pictures.

Had to have my friend take pics for me and send them on.

Look at those fat buds. Way better than the 1000w HPS + 200w LED, just needed to up LED wattage to nearly 600.

Certainly a drastic difference in bud formation with the additional LED power compared with my last grow.

I use UVB supplement specifically to add crystals to the plant. UVB is a key spectrum involved in the THC creation process. You get these at your local reptile pet store and they fit a normal light socket. Highly recommended.

Actually most fluorescents emit UVB - they utilize two mercury lines, in UVA and UVB range to generate light. It just depends on the glass type as to how much UVB you'll get. Also, almost nobody shows UV or IR spectrum for fluorescents, and while there's not much IR there's plenty of UV.
