LED Ahoy!

Week 5 beginning! Let's have a look before I go changing nutes!

Since my blue-dominant flowering test finished, I took those two 15w spots out, put them on clamp mounts, and I'm using those to cover the undercanopy.

This will do a fair job of increasing my yield for very little power.

Week 5 ending! These colas are beginning to swell and really really smell!

I also have excellent progress on the 9 pack in the Krusty under the 50w, plus great results under the 50w. I must say though, the larger panels definitely put out better buds.

Oh well, that just means I need to design a heat sink that will allow me to cram 150w into a 50w panel. Can't use solid aluminum, might need a composite. Hmm...

Besides that, plenty of milky goodness all over the place. Trichomes are fairly dense and clouded. No signs of any amber as of yet, but that will likely change in about two weeks.

hey bro, i bought and now using 120 watt triband led light (119leds 1 watt each) they claim its a 600 watt equivenlent, so far with your grow do you feel the leds are worth the effort?
i also have a 430 watt hps 3 feet beside it.

In veg phase, 120w LED=600w HPS is a decent claim to make. For flowering, not so good a claim to make, it's more like 300w LED=600w HPS.

So far, now that I fixed my airflow problem, yes, the LEDs are doing a great job and I most definitely see them having been worth the effort.

i need some advice on a system i am putting together im gonna be using a complete hydroponic system and i have purchased 4 led panels with a wave length reading of Red: 640nm Blue: 460nm they are 56w each units do you think these will produce a positive result or should i step out and purchase another few panels and make it a 400w plus system? store information shows the comparable to a 400hps but ive only grown under hps -mh systems so im nervous about my purchase i hope an honest opinion or some knowledge will reassure me with my decision to move with the future of lighting and it makes my pockets cry much less at utilites time

I think this would depend on the type of panel. You said 56w, the only 56w panel that I'm aware of uses tail-through 'lite-brite' diodes. While these panels will work, they won't work as well as a panel using SMT diodes, which will output much brighter at the same power draw. Also, you'll have to keep those panels further away from your plants so to allow the light to combine and cover the plant evenly.

Total 224 watts of LED. Well, if you do everything right, you should match a 400w HPS or MH without too much of a problem.

So are you using 2 different lights or strengths from veg to flower??

I'm using pretty much the same panel all the way through. For the larger plants, I added a couple of screw-in LED spotlights to help cover some of the undercanopy and get more production down there.

Week 7 begins. Would have posted on Saturday but the forums were down.

More pics coming.
