way to go on the lavander. what light set up are you using to get 50uw? Intetresting when you supplied it plants died and fried. pot tends to grow well in those areas around the world.
I camped, fished, hiked all over that road to Denali for 5 years. First time a game warden saw me fishing in one of the streams crossing the road as he flew over. He landed the plane and tracked me down to make sure wasn't fishing for salmon that early in the season. I had a trout lure on so was safe.
My current reptile light is ArcadiaD3+, 12% UVB, 25% UVA. With a polished aluminum 2" reflector it puts 50 uw on a leaf at four feet away, good coverage. Lumitex has a passive 105 watt UVA/UVB light bar with approximately the same ratio for $500. The LED bar should give double the coverage, but until it is bought and tested that is just a guess from the advertising blurb. Probably next winter for the purchase.
The third day fried plants took 2,700 microwatts. High noon at solstice in Texas is only in the 600 uw range. I was doing a top down overkill to more quickly find the max the plant could live with (800 uw, barely alive). The stunting overwhelmed any benefits at about the 200 uw mark, more did not add effect and the dwarfism got worse until 900 uw would slowly kill the plant.
This is a simplification, the ratio of UV to the rest of the spectrum as well as total intensity is also a factor.
On the other end of the spectrum is Far Red. Two years of testing are about over. Far Red was used from 13 watts per square foot through 40 watts per square foot. On/off times ran from 12/12 through 10/14 for the overheads, 30 minutes overlapping the on/off times, up to all night long for the Far Red.
No hermaphrodites, even with major stress. No random seeds, even with Sativas.
The buds were neither larger nor denser than the years before the Far Red. The light schedule finally settled on is 12.5/11.5 with Far Red (250 watts, 70 square feet) on the entire dark period. Paying for the extra hours of light did not increase yield so I am taking the stabilizing benefits and leaving it at that. All those tiny sterile seeds in the Sativas were a annoyance that is gone.
Hermies from the cats opening the vents is over. The summer season and all night light is back, with the Far Red on all night the vents do not have to be light tight.
As long as the deep red leaking in is less than 15% of the Far Red already there then the light leak does not even exist as far as the plant is concerned. Less stress for me.
So I still swear by the Far Red, I just do not expect it to give me bigger buds.
I still swear by UVB, even though it gives less weight the more it is used.
If pure yield is the goal, I have yet to see SOG with HPS surpassed on a yearly average. HPS is not allowed in my garden at all, personal choice. Nate, my nearest neighbor with a garden, uses HPS in all his rooms. Arguing which is better never comes up, we both reach our goals.
Can you explain more how you use them
Distances times ?
Good.luck on your extraordinary journey
It is amazing to share such experience for me coz its kinda my dream setup.. good job good luck best wishes wonderful vibes
How about amares uvb bulb ?
