LED Ahoy!

Posted 6-20-2010

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!

Okay, never mind, so we both got a start on 12/12 around the same time as I started on 6/11/10, 9 day's later you weren't certain but it hadn't been 2 weeks just yet.


I've gotta say the Tric production looks better than mine, but the buds are looking a bit on the weak side,...

I'm pretty much disappointed in my buds ATM, but I know very well that I have at least another 2-3 weeks before things are finished, perhaps the LED's will bring it out on the last half, and if so,.... how do I get ahold of you for a test array,... I'd love to have more light, but I"m already maxed out for the circuit.imp:

Pic 1: the top
Pic 2: A couple lower buds,.. tric production seems to be better on the lower buds for some reason? :wtf:

2-3 weeks before you're finished, must be a short-time strain. I've still got another 6 1/2 to go. It still looks nice.

As for trich production on the bottom, blue light penetrates better than red light (higher-energy wavelength) and it seems wavelengths in the blue play a major role in trichome production.

As far as the time left, I don't really know, it's my first grow, but if it's what its supposed to be then yeah, I shouldn't have much time left.


I'm flowering under 400w HPS "plantmax" bulb in a 33x 60" space,... I'm not on Skype Yahoo or anything really,... but I am interested in LED's there's just too much potential there, it's just seeing the proof of the pudding that I hesitate on.


Also,... what about veging under LED? :wtf: I'm limited to the # plants I can have, so I don't want to waste space and as such have tomato's peppers, lettuce, and such growing as an indoor crop.

Veg under LED is where LED really shines, IMHO. This is where the claims of "90w LED = 400w HPS" are actually true. I have done much vegging under LED, and the results are just incredible.

For example - here are some pepper shots, day 1, 5, 9, 13, under 90w LED

There's a tomato on the other side, the next post will have shots of that in veg.

[khyberkitsune]

As promised, the tomato veg shots, same day spans, same 90w light!

Nice! :thumbsup:

confused about this. red and blue are present at the top of the plant but at the bottom there is far less red?if this is so than shouldn't you say the presence of red inhibits trich production or that the lack of red allows trich production to be more fully expressed? I'm not an LED user yet but am very curious about the interaction of the different spectrums.I flower under a HPS but ripen[the last few weeks] with a MH.

"red and blue are present at the top of the plant but at the bottom there is far less red"

Pretty much, yes. Near the bottom of the plant, white buckets have way more of a blue glow versus red.

"if this is so than shouldn't you say the presence of red inhibits trich production"

No, because red has no inhibitory role in plant growth. The primary purpose of red is to produce flowers and fruits, plus some photosynthesis.

"or that the lack of red allows trich production to be more fully expressed?"

Again, no, because trichome development is ALMOST entirely dependent upon how much potentially damaging radiation the plant receives during flowering, and red radiation isn't damaging enough. The more blue you add, the better. That's incidentally why you finish off with MH, the blue makes it better. It also adds more bulk since blue is responsible for most actual growth and bulk production.

thank you for the detailed response it does help me to understand but some more questions if i may?if red neither helps or hinders trich production but it is mostly dependent on the blue why have red during the final weeks of the plants life? also there is more blue at the top of the plant- shouldn't there be more trichs up there also? BTW beautiful plants khyberkitsune

Red is there for mostly photosynthesis after flowering has begun. Red is more efficient for photosynthesis than blue and thus keeping it in steady supply is considered crucial to a proper yield.

There are more trichomes closer to the top than at the bottom.
