Thanks for the feedback, much appreciated. Im probably going to get 4ft kit for 140. Do u know if they send everything you need to run the lamps close 40 watts each? I noticed something about needing an extra wire for the ballast to get it to run at a higher wattage, or else its 20 some watts per lamp.

32w a lamp. I wouldnt run them up any more than that. 2 of them for a 4 x 4. Didn't really pay any attention to running them for more power.
At 32w they are more powerful than any other UVA/B bulb, and they are also the only bulb made that allows 280nm of light transmission.. The lowest end of UVB, and the Highest End of UVC.
From what I gather the Solacure at 32w is 2x more powerful than the 54w Agromax Pure. They say their buld is 15x more powerful than a reptile bulb.. Doest]nt say which 1s. But the Solacure FlowerPower is at least 30x-50x more powerful than any reptile. bulb.
Consider the Arcadia 54w Desert Reptile bulb is the most powerful Reptile bulb, and will give the Solacure 30x the power of this bulb vs up to 50x vs less powerful bulbs...Like Forest Reptile, even though they are 54w...
At 15% claim vs 30% on the surface it appears the Solacure is 2x more powerful and is only 32w..... Solacure also goes down to 280nm,

Hmm, sounds like you are using their “super b” lamp, at 32 watts. Or are you running the “flower power” lamp at 32 watts? On the site they state the flower power at 20 or 40watts , and the super b at 32 watts.

Flower Power F40 (4 foot)
Specifications:
FR40T12 multi-wattage, multi-peak UVB/UVA horticultural lamp.
Wattage: 32-40 watts standard, can be run as high as 80w for special applications.
Color: white to violet. Color temperature >10,000K
Dimension: 4 foot by 1.5 inches. Will fit almost any shop light.
Reflector: Built inside the lamp. No external reflector needed.
UVA/B: 5x the power of the SG-1 and Universal UV. About 20 to 50x the power of reptile lights.
UVA/B rating: Equivalent to a 30% UVB lamp, but we do this in very different frequencies, so they don't equate.
Life: 1000 hours at 70% of original power.
From the ground up, this lamp was engineered to do nothing but operate as a horticultural lamp. It can operate as low as 25 watts and as high as 80 watts, but is centered to us a standard 4 foot 32w fixture and it's own timer. It is four foot long, 1.5" in diameter, so it can be used in virtually every 4 foot fixture at the hardware store. Our entire goal was to make it simple and cheap to operate. All the really interesting things are happening inside the lamp, not in the fixture.

WRONG. FAKE NEWS.
Plants respond heavily to UVA/B, and was proven by NASA as far back as the late 70s on Skylab. High Times had the study in the magazine in the late 70s.
They also experimented Xenon.
Marijuana was one of, if not the first plant studied on Skylab. They proved they could change the cannabinoid profile with different light wave lengths. Yep. They sure did. Decades ago.

Uv would compliment a full spectrum, led is and never will be, so many gaps its like a sieve and weighted wrong.
Ya the copy and paste info would have you believe but i could change cannabinoid profiles with a variety of non light things so even the info on the science is bs.
Join the led crowd, i dont and say it how it really is, expect the hate as they cant discuss what they cant prove

Ya but did you read the studies that didnt get hyped where a simple gas or addition to the soil also changes cannabin. profiles and all the other science on it you missed since the last decade.
Jeez if i had a penny for all the brohype, wouldnt be growing weed for my local neighbourhood....!

I don't use LED, I use either 1000w Gavitas, or 1000w Hortilux. I also veg with them. Been using HID since 1978. When they first came out. Grew my 1st plants in 1972.
All I know is its 100% for sure UVA/B triggers a protein in marijuana to protect it from harm, and was proven by NASA in 1979. NOt here for an LED/HID debate. Only that UVA/B does work.

Yes but the reality is no one here has had any real noticable dank or yeild from uv, years and years of hype and zilcho, well a few less served members claiming they can notice a difference.....
but why even chase this unicorn thats going to make no real difference when you could be using your time with stuff that will give extra yeild and dank.
Man comes here and first stuff he hypes is all the stuff we never got anything out of but apoarently nasa or the secret service or some new grow click has produced super tripple strength bud from.

Doesn't make a crap to me if anyone uses it or not. I do, and will continue to do so.
I just know it made a strain weve been using for several years considerably better, and everyone that smoked it agreed. Been using them for over a year now.
Solacure also goes down to 280nm, and 285nm has been proven to be responsible for a stress regulating factor.\
No other bulb goes to 280nm.

UV-B resistance 8 (UVR8) also known as ultraviolet-B receptor UVR8 is an UV-B – sensing protein found in plants and possibly other sources.[2] It is responsible for sensing ultraviolet light in the range 280-315 nm and initiating the plant stress response. It is most sensitive at 285nm, near the lower limit of UVB. UVR8 was first identified as a crucial mediator of a plant's response to UV-B in Arabidopsis thaliana containing a mutation in this protein. This plant was found to have a hypersensitivity to UV-B[3] which damages DNA. UVR8 is thought to be a unique photoreceptor as it doesn't contain a prosthetic chromophore but its light-sensing ability is intrinsic to the molecule.[4] Tryptophan (Trp) residue 285 has been suggested to act the UV-B sensor, while other Trp residues have been also seen to be involved (Trp233 > Trp337 > Trp94) although in-vivo data suggests that Trp285 and Trp233 are most important.[2]
The targets of UVR in any living cell are DNA, lipids and proteins (which form enzymes and hormones). DNA is the genetic material in all living organisms, that is passed on from generation to generation. DNA damage will occur whenever the organism is exposed to UVR. Yet, DNA damage is not simply bad news. UVR has been an important evolutionary force, generating mutations, leading to new traits, and driving the development of species diversity. Mutations are, however, mostly negative, inhibiting vital cellular processes (DNA transcription and replication) and resulting in disturbed cellular function, sometimes even cell death. Fascinatingly, plants exploit blue and UV-A wavelengths to drive DNA repair processes. Researchers have showed that DNA damage due to UVR is mostly repaired by subsequent exposure to light in the blue or UV-A range of the spectrum. This is because blue light and/or UV-A exposure activate an enzyme (photolyase) that repairs damaged DNA sequences. The beauty of this system is that when plants are exposed to UVR, there is always a lot of blue light present. The involvement of blue or UV-A light in this process is known as photoreactivation. Photoreactivation is the major defence against UVinduced damage in plants. Apart from photoreactivation, plants have gained many other adaptations to cope with UVR during their evolutionary history.
Light
Plants grown under UVR are beneficial for humans
Plants are an essential resource for humans in many ways. Each atom of carbon, that builds our body, is first taken up by plants and fixed in the process of photosynthesis and only then can we use it. The same holds true for minerals that come from soil and become available to humans with the assistance of plants. Beside this, plants also produce many important protective substances and vitamins that are indispensable for them, but also benefit us, since our bodies are not able to synthesise them. You probably know vitamin C and antioxidants are important components of healthy food. We have already learned that the production of many beneficial compounds is triggered by UVR. The most important group of chemicals are the phenolics that exhibit a wide variety of beneficial biological roles, including antiviral, antibacterial, immune-stimulating, anti-allergic, anti-inflammatory, anti-carcinogenic and others. They are also powerful antioxidants scavenging reactive oxygen species and free radicals and can bind (chelate) with metal ions such as iron and copper, enabling our bodies to use these important micro-nutrients. Important sources of phenolics are different herbs (i.e. medical plants), fruits, vegetables, grains (i.e. buckwheat, wild rice), tea, coffee beans, bee pollen (propolis), and red wine.
UV might increase the amount of active substances in medical plants Many studies have shown that enhanced UVR, especially UV-B radiation, increases the amount of active substances in many plant species. We have already mentioned the importance of different phenolics (i.e. flavonoids, stilbenes) and vitamin D, production of which is stimulated by UV-B. Vitamin D is also synthesised in plankton, which is then ingested by fish and can eventually become human food rich with vitamin D and beneficial to health. UVR stimulation has also been shown to increase plant production of different (phenolic) alkaloids, essential oils and terpenoids, that have known medicinal properties.
Plants
UVR enhances plant food quality Human efforts to increased food production and to control plant production have changed basic environmental conditions for plant growth. Plant breeding has increased the yield of plant cultivars, which require irrigation and fertilisation during the entire growth season to ensure favourable harvests. Plants are also cultured in greenhouses to avoid different pests and weeds and to prolong the growing season. Because of long distance food transportation we often consume unripe fruits that are usually poor in phenolics and vitamins. The race for more food that is grown faster has neglected some basic things; (1) Everything in nature is question of cost and benefit. Thus, if plants invest more in yield it is likely that less energy will be left for investment in secondary chemicals for plant protection; (2) If plants are bred to grow in a favourable environment they will lose the natural genetic adaptations needed to cope with adverse environmental conditions. Therefore, it may happen during drought that poorly ’equipped‘ plants will be more susceptible compared with plants growing under natural conditions; (3) plants subjected to intensive breeding might have lower potential to produce beneficial phenolic substances following exposure to UV-B; (4) many studies show a negative effect on food quality when the natural UVR dose is reduced in greenhouses. Culturing plants in greenhouses might have two adverse consequences: less radiation at visible wavelengths for photosynthesis and less or no UVR (due to glass or plastic covers that block UVR). This latter reduces the production of UV induced phenolic substances.
I just know it made a strain weve been using for several years considerably better, and everyone that smoked it agreed. Been using them for over a year now.

Reading about uvr8 was what made me start to look into uv. I first heard about the protein on some video recording of some canna related talk on youtube. It was just something that was mentioned as a sidenote but raised my curiosity. They even mentioned increase in some sesquiterpenes with uv supplementation.
So i guess apparently nasa isnt good enough, but we need a consensus on some internet forum for kinggrow1. Nevermind the fact folks over and over seem to have been using inadequate amounts, in addition to having countless other potential issues in any given garden.
Now you have one member whose seeing value in adding uv to a know plant, yet you are totally willing to dismiss it.
Edit: not to mention if running another 60 watts for a 3-6 hours a day for a small grow like mine is going to make life difficult for any potential bugs or molds, its worth a shot.
