Trichomes, THC and UVB light.....

I have noted before that when I flowered beneath both red and blue (hps and mh), the colour of the bud seemed more intense than that just flowered under the red.

Also, have you seen the list of my nutrients?

The color of the bud won't change from using LEDs. just texture and potency. If you want to change the color of your bud what i use and would stronly recomend is the purple maxx snow storm stacker developed by Humboldt County's Own. your node regions will be stacked, massive trichome crystalization, and depending on the strain of your bud. it will turn your plant purple and you will be loving it. use with kelp extract or "gravity" which is a bud hardnerfor maximum results.

I have 2 beautiful girls one is almost done that was only under hps during flowering...the other has about 4 weeks to go but the first 3 weeks were under mh. didnt grow too much so i put it under a hps an man it looks so much more potent the the other we will see i defintly will try to post pics on this thread when their done. i really think its making a big difference but i do think i'm going to end up with less.......but stronger!!! and thats what i want so fine by me

Arcadia - Home A wide variety of fluoro units, designed to promote plant growth in Aquaria and vivaria. nice COMPACT, cool running and reasonably priced. all types of ballasts and lampholders, inc several UVB/actinic. They also stock metal halide lights, 150,250 and 400watt in V.trick, compact holders with integrated timers, starters etc-worth a look

Well 24hrs have passed. The plants are not positively leaning toward the UV light source, neither are they leaning toward the CFL propagation light. So a change has occured, the light must have satisfied some basic requirements. I will now use CFL solely for a while, just to see if there are any late showing problems. I will then use the UV light continually on a known plant in late flowering.

Okay, the lurker is gonna chime in.
#1 - I think, and I'm probably wrong, that from the moment the seeds go into the paper towel, UV must be present.
#2 - Again I think, the plant if not exposed to UV will lessen its ability to protect itself_this will happen over the time it takes to develop a 'new' strain.
#3 - I think_ :lol: _ that plants get sunburn.
#4 - Everyone who just guesses at their ph_raise you hand. Hmmm no hands. So why would you put UV into the environment and not have a meter?
#5 - Lastly, thanks to everyone for their input. Collectively it happens a lot faster.

Yeah blue and red are required for the best results:blsmoke:

In these pic's the guys... Skinny on the left, and Fatboy on the right in the second pic... have been under constant UV for seven hours. They are yet to get rid of their seed casings.

I think I imagined a quick death. Fatboy has very vibrant green cotlyedons that can just be made out beneath the casing. Currently there is no other available light to the seedlings. The light is a 300w Osram Ultra-Vitalux. The first 90 hours of the bulbs life are where it's at it's most unstable, and can give both UV A and UV B readings that are off the scale. Indeed, even after 3000 hours continuous use this bulb will put out higher UV readings than anywhere found on this planet.

The center of the lamp is 27" away from both plants.

Hey folks I'm curious say someone was using only T5 in say an eight bulb system, In theory would a mix of 3 blue day bulbs and 3 warm red bulbs with 2 of these lizard uvb lights get better results during flowering. And would the T5 lizard lamp work in any T5 flourescent fixture. bearing it's a typical bi pin?
Just curious I think someone would be willing to make this experiment happen. Following any good advice you might have to offer.

If the requirement of the uv lamp is within the operating range of the ballast & if the electro-mechanical_how it connects to the fixture_are the same, then I would think you got no problems.

REMEMBER UV IS NOT GOOD AT ALL FOR YOUR EYES. Either wear UV eye goggles or turn the bulb off. It is radiation--therefore, time and distance are your friends.

I have just started a quick and dirty trial. Noticed that my vegging clones are orientating toward the centre of the existing light source, and that they re-orientate themselves in one light cycle. I have set up a UVB 420 fluoro to one side and will check in 24hrs on the orientation. I think if UV is offering an advantage, the plants on that side will react accordingly. the bulb is an Aquarium moonlight simulator and is designed to assist marine photosynthesis. Iwill re-post 24hrs hence.

Is it time yet? :joint:

Another couple of pic's... from these you will notice the repositioning of the pots. You might also notice the direction in which the plants are pointing.

Earlier the plants were pointing the other way, I merely moved them to the other side of the light... only 3" closer, and added a fan.

They've now been under 26 hours constant UV, with it being their only light source.

As long as the lamp is a decent distance from the plants you wont burn them at all however long you leave it on for:blsmoke:

I try not to look at the light for too long... but when i do i can see a mixture of colours, different hues. it looks kinda white... but with tints of green and blue... very subtle though.

The plants are showing a slight sign of stretch. But they do look incredibly vibrant, and healthy. Probably much more so than had I been beneath that light for 32 hours.

They have their first set of true leaves. Although I've never grown this strain before, but it does seem very healthy thus far.

Yes, they seem to like the light... but this is their only light source. maybe it's because they have no other choice. The light was on when I took the pic's.

I think the UV is just naturally more intense. Maybe this is the light cannabis favours the most. Then again, maybe they will die. Either way I must start germinating the NL today or tomorrow.

The light is 24" away at the moment and i may decrease that to 18". The heat output from the lamp seems to be about 12". The stems grew thick and strong straight away. Skinny has now completely unfurled the cotyledons and is looking just as vibrant as Fatboy.
