LED Ahoy!

[khyberkitsune]

Okay, this becomes my new official grow journal. 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, as I'm flowering them now and will relegate some fresh clones to mom status. The prototype 50w gets the 5-site DWC SoG bucket. The 50w tri-band gets two DWC plants, taller than the others.

I'm a little shaky on when I started the flowering, but I know it hasn't been two weeks, and the buds are really just now starting, so we'll say this is the beginning of true flowering and roll for 10 weeks!

The fourth pic is of the 5-site DWC with a flash to simulate what it would look like under the prototype, as while the human eye has no problem seeing the green from three white diodes, the camera simply cannot due to the red and blue overload.

Thanks for that. I was wavering but not now.

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.

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.

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.

Yes you could supplement with 6500K CFL no problem!

WOW those lights are really awsome man I was going to buy a UFO but ended up gettn a 400 watt system in stead but ya jeez mad growth in that amount of time

Thanks will look into it. Might shoot you a PM later.

No PM system installed on this forum.

Feel free to contact me via AIM, Yahoo, MSN, Skype, etc. I prefer AIM, Yahoo, or Skype. MSN is a pain.

I have a little bit of extra cash and have been reading about the benefits of vegging under LED. What LED size would replace a 600 MH? Hopefully it will cover a 4x4 area.

Thanks for your time.

Replace a 600wMH for veg. You can do that with a 120w or higher LED panel.

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.
