View Full Version : LED chamber test 3, floros & 90w 660 LEDs (now with pix)
10-11-2006, 08:44 PM
guess it is about i gave this run through it's own thread.
4x22w vitalite full-spectrum t12 floros. (24" long) = "o"
6x15w 660nm LED strips. (24" long) = "-"
because one of my floro fixtures is a double fixture the lights are aranged in the following fassion:
and this arangement completely covers a 24"x24" square.
the chamber is 16" tall and 25"x25"wide. the top and 4 sides are covered by panda tarp. on side can be pulled back like a door.
flowering plants are in a quart of soil each. they have good root growth but are not particularly rootbound. they are at 7 weeks from germination now.
one early observation is that the flowering plants have started to lean away from the to main and possibly overwelming (can you say saturation level?) LED strips.
i have yet to add the blue LEDs. that will be in the next grow i expect. this makes me certain that i want at least one of the the two blue strings to be hang from the top between the 660 strips.
more to come as it develops. :)

i want to see the blue--betcha it make a big diffrence:) Thanks pf for the expiramentation---i had a similar experiment to see what spectrums at what phaze had an impact. But not with leds--too expensive for me:)
i did notice that any type of red only gets yo so far though.
Bout time:D Now I have a better visual of what your doing. When you add the blues you will want a wide angle LED if you only want to use two. It will give a better even spectrum on the canopy.

i already have the blue strings of xmas light LEDs. they were given to me so i can't argue with free. they have a very difuse projection pattern. i have 2 strings. one will go around the periphery and the other will be interspersed over the canopy.
if i spent money on blue LEDs i would by 4 or 5 royal blue 5w LEDs with wide angles. this would be enough to cover the whole garden and only would cost about $100 plus power supply.

Vitalite grown AFBB: Smell is pleasant and similar to DJ short BB mom, not strong. 0.3g took about 20min to smoke. Very nicely high. Mostly feel it in my neck lips and shoulders. Distinctly buzzy. Happy, relaxed, muscle relaxation and no tachicardia. At about 30 min from start of smoking, the high is progressing into a strong stone. Very pleasant and worth the effort. The sensations are strong and somewhat unique. Blance is effected at 35 min and there is now a strong sense of “mind expansion”, like my thoughts could wonder on tangents forever. Meditation is strongly facilitated. :)
40 min. Mildly sleepy and very stoned, some munchies. 45 min. After eating a slice of pizza I feel less intensely high but still nicely stoned. 1 hr. Still noticably high and buzzy (about what it was after the first bowl of 3). Pritty much at baseline at 1 hr 30 min.
Vitalite and 660nm LED grown AFBB: Smell is overwhelming, even with it sitting across the room. A little acrid and very pungent. Over all flavor is that of the DJ short BB mom with a hint o the lowryder pepperiness. Burns my nose. Almost unpleasant but not quite. Taste also somewhat stronger, however it is not as well cured so flavor would change some over time.
Some What harsher but finished in 0.3g in 15 min (5 less than above). At 10 min the high became very visual. There is strong buzzing in my body, forehead, behind my eyes, and in my lips and tongue. My muscles seem relaxed but I have the slight perception of jerkiness without any actual sign of twichiness or tremor. BP seems a little up but heart rate is ok. Over all I am happy with very nice pastel patters and colors over everything and good closed eye visual production. My thoughts are accompanied by much more intensely real movies than usual for myself. There are many qualities about this high that remind of of the LED grown catalyst which I still have small amounts of left. (Even after all this time it still produces the same intense cerebral effects.) Deffinately a sense of time slow down at 23 min after I stated smoking. Over all decent pain relieving effects. This is very nicely potent. I think a little more so than the plain vitalite grown stuff I smoked lastnight. It is actually annoying to write this the mind expanding effects of this cannabis are so enthralling and powerful. This is also definately more of a head high than the stuff lastnight... less of a stone.
30 min. “What is spirituality to any one person? Is it or should it be the same in everyone? Can truly spiritual experiences ever adequately be vocalized? Should we even try? Psychology says there are some internal experiences for which our perception and understanding degrades if we try to vocalize them. Some spiritual experiences are in the category for me.
What about Enlightenment? Spiritual or other wise? Can this phenomenon ever truly be conveyed to another? It often seems Enlightenment can only be reached though one's own individual path. Likewise, all one can do for another is provide stepping stones on this path but never the actual enlightenment itself. But like death and all our human experiences, penultimately we walk into that light alone.”
45 min. Still lots of buzzing, especially in my arms, chest, and head. Less buzzing in my lips now and more in cheeks. Less munchie effect than I remember lastnight. I was sneezing a lot before I started this test and now I have much more intense cotton mouth than I remember having lastnight but my sinuses have stopped running. :)
Skin sensitivity activated in a pleasant fashion. :rolleyes:
Overall very happy with this. If I had to rank their potencies I would put lastnights experience at about 8 out of 10 and tonights closer to a 9. Yield however does not appear particularly effected. There were 8 plants in my first test that were all of decent to large stature for my particular AF genetic line. In this test there were 9 plants all together but was tall and lanky and all but 2 of the rest were smaller than average or even dwarf for my genetic line. So actually comparing the yields of the too batches may not be that informative other than to say that there was no obvious effect on yield either way. (Hey at about 1 hr I feel very nice concentration/anti-ADD effects from this test. :D ) Another issue that slightly compounds comparing the two directly is that in the first test 4 out of 8 were seeded on the lower four budlets but on this test all 9 were seeded on the lower four budlets for breeding purposes. I didn't really think about the effect of this until after, can you say “D'oh!”? (1 hr, 30 min. more or less back to base line.... only slight buzzy feeling remains.)
All plants were cut at soil level at harvest time.
Vitalite (20w/ft^2) only test: 8 average plants.
Total: 5.5g/8 plants ~ 0.69g/plant
Stem: 0.2g/8 plants ~ 0.025g/plant
Seed: 1.0g/4 plants ~ 0.25g/plant
Bud: 4.3g/8 plants ~ 0.54g/plant
660nm LED (22.5w/ft^2) and Vitalite (20w/ft^2): 9 (3 average, 6 smaller than average) plants.
Total: 5.0g/9 plants ~ 0.56g/plant
Stem: 0.4g/9 plants ~ 0.04/plant
Seed: 2.0g/9 plants ~ 0.22g/plant
Bud: 2.6g/9 plant ~ 0.29g/plant
With this number of plants I am only using 2/5 of the LED chamber's max-fill potential.
pictures to be added soon. :)

here is a link to the grow report for the first vitalite only test.

i think that i have been staring at this reply box for an hour, thinking about various things that you talked about. smokin of course.
my conclusion; i think you talked to god. so you smoked some pretty good shit.
ive smoked a j and half, the white zigzag 70mm and im sure that i didnt smoke 32 leaves already, the guys at the smoke shop i feel are taking leaves out of the pack and zz should seal the pack, next time im counting them in the drive thru.
could you put the data in a pie chart. i like pie charts.
oops grandpa gens coming, gotta go
11-03-2006, 09:42 AM
sorry pf. forgot to lock the study last nite. kids today. i blame it on the pot.
11-03-2006, 08:04 PM
eh? <raising one eyebrow>
hehehe i liked you reply gen. even if it was not actually you.
11-08-2006, 12:57 AM
just thought i would add lisa's limited comments. she likes the stone better on the plain vitalite autoflowering blueberry but today said that the LED/floro grown AF BB is "really good for the arthritis in my back". "Good pain relief".
11-08-2006, 11:50 AM
lol...kids are fun huh gen?lol
i love strains that are a good for arthritis.:D
11-08-2006, 05:30 PM
for all those that say that AF plants do not have medical properties... :p
11-10-2006, 09:02 AM
hello pf, just saw this thread, so came over to see. Sounds like you nailed it, eh. Pretty good. How about some photos.
11-20-2006, 05:49 PM
yeah i really need to get on the photo's don't i? eek my camera needs purdging lol.

here they are in all the tiny splendor.
and here are the ones grown under just floros for comparison:

Nice breakdown on the stem, seed and bud results.
From the pictures, the Vitalite plants look larger and leafier. You didn't think to record the fan leaf wieghts did you? I wouldn't have thought of it until afterwards, but it could give some indication of the LEDs stimulating leaf vs. floral characteristics.
Do you think the LED + Vita plants matured faster than the Vitalite grown plants?
Did you observe trich developement earlier on the plants with LED + Vita than without?
Given my experience with Red 660nm LEDs, faster maturity, with less trich developement, but with higher THC profile would be likely for the LED + Vita. Assuming the LED + Vita spectrum had higher Red to Blue ratios (faster maturity, more potency) and lower Far Red to Red ratios (less/smaller trichs) than the Vitalite alone.
12-15-2006, 06:15 AM
damn no didn't think to way leaf matter but i should have. i can't say whether the size issue was from genetic hit or miss issues or if it was from the light. very hard to say with out more results.
maturation time seems to be about the same. if anything tho i would guess the LED+Vita took slightly longer.
no idea about if triches showed up earlier really have not been taking notes on timing of stuff like that. my bad.
my results tho are big fat triches and a lot of them, especially on calyxes with LED+Vita. density on sugar leaves might be less but hard to say without a side by side comparison. i would say more bigger triches and higher THC profile but potencially smaller plants with LED+Vita as compared to Vita alone.
