Calling out to Weezard for LED advice

[ledtime]

You have scored!.:thumbsup:
This is getting very interesting!


Weeze

Wow...I've got to get some kind of glasses. That blue light makes my vision funny for a few seconds! I don't even look directly at the bulbs.

I'll keep you updated with the results.

How your inside grass is better while our outside grass is better I don't get since you have much better weather. May be you have to grow stealth while we can grow 15 ft trees. Weed can never fully develop like that inside.

"As for light saturation.
91K lux, (of solar spectrum), is about max. I'm guessing it's a bit less for LEDs because of the higher absorbtion and the lower sensitivity of the meter at those wavelengths.

Just my 2 cent, but I think we're on to something.

Aloha,

Yes, we are getting somewhere. 90K must be right, because the maximum found is 100K, right in your backyard as a matter of fact.
That 90K translates to 8.370 lumen and the better your spectrum the less you need.

But do I understand this correcty?
Roughly the solar spectrum has 25% blue and 25% red and long waves have about 10 times more energy than short ones.
So do I need 10 times more wattage blue light than red to get about the same amount of lumens?
If this is correct I don't get why they put so many red leds in these growlamps either.

Hey Bubbleblower,

Those are the exact same glasses DreadedHermie has!

You raised a very interesting question in regards to Weezard's location. I too would think outdoors in Hawaii you could grow some stuff oudoors that could do some serious damage. Heck, I'd be growing some Thai sativa at least 12' tall. And if that wasn't enough I'd give it the old opium/water cure to insure smoooth smokeing and a mellower up high. But that's me.

Oh yeah! The outdoor weed is terrific!
But the indoor grown is mo' betta for potency.
My outdoor girls are limited by their containers. The same size containers as the indoors clones of course.
I do have an indoor mamma in 5 gal DWC that's gettin too big for her parlor. And I do have a 6' Sativa outdoors only.
(Not suitable for indoors.)

I have security concerns so my ht limit is 8'.
I'm legal, but we do have to worry about rustlers here.
Um "old opium/water cure"?
Care to elaborate?

Wondering Weeze.

Same ht limit I had in my grenhouse, just use bushmaster.

Yup, same problem I had last fall, the crack heads got me greenhouse....the only good thing about that, my town seems to have 3 less crack heads around now.

Real Thai stick is dried and cured using tar-opium mixed with water, it usually is sprayed on the trimmed buds as they dry. It really makes a difference in taste and smothness of smoke, even in a bong. The US military had a problem on their hands with returning troops, many of whom where using red rock heroin and gray rock, either snorting or smokeing it. So when they started randomly testing the troops they got positive hits on so many more then they thought they would. The problem was the pot smokers where testing positive for opiates even tho most never did the heroin. When they went to mandatory testing before troops went home, they had to quantify the opiate tests so they didn't snag 1/2 the army and air force from returning home.

So, seeds were planted on June 5th. They sprouted on June 8th. It's now the eleventh and at 6 days from planting the seedlings are about 1-1.125" tall. Their stems are THICK. They only have two blade leaves so far.

The interesting thing is the roots. There was at first the main root...nice, white, thick and long. Now roots are coming out of the sides of the rooter plugs everywhere! I wasn't expecting this until sometime next week.

I am raising them up in a bubble cloner if that makes any difference. They seem to be really liking this dual blue light I'm working with here. I'm not sure what strain this is, but I know it's grown in Jamaica.

Figured I would just let you know the progress. Oh, and with no ventilation fan on in the room the temp stays around 79-80 degrees. Pretty tame from this light.

sounds good ledtime. how bout you start a grow log? that way everyone could follow along. i know many are interested in LEDs and it would be good to show what they ARE capable of doing.

got any pics?!

So, I have the light about 5" above the plants and they are showing signs of leaning towards the center of the light. I'm going to raise the light up to around 9" and see if they straighten out.

Other than that they are doing quite well running under just the blue lights. It's been 14 days since I planted them. Until today I was just running 5.8PH tap water at 160ppm with one drop of superthrive per gallon.

The plants have developed slowly the first week, but now by the end of the second week they have 6 alternating pairs of leaves. The roots are growing down into the bucket through a ten in pot filled with hydroton. I just took the seedling in the rapid rooter from the bubble cloner and put it into the hyrdroton.

I'm using Latewood's formula for nutrients at 1-1-1 in veg with 1 being equal to 80ml per gallon. I just started this regiment today after draining out the superthrive tap water. I'll be topping off what liquid karma as needed and swapping out fresh nutrients every 14 days or so. I can't tell the strain yet, but they look as though they may be some form of sativa. The root growth from this blue light is OUTSTANDING. The plants are staying low and growing out. About 6 hours after swapping in the nutrients the plant leaves grew out about .25"! I've been keeping my nutirent solution around 70 degrees.

Just thought I would provide an update. The mixture of the two "ideal" blue wavelengths seems to be really growing this nicely. Explosive root growth. Low to no stretch. I love how the leaves have a nice dark purple hue under this light. Would make for some amazing pictures!

Here you go. When I have the priveledge of posting pics from the forum I will upload some.
