Look into the 34w Solacure Flower Power Lamps. UVA/UVB.
Its WAY stronger than the Reptisun, or Arcadia..
Solacure will burn your eyes out. They also make 100w, but they better be a long way off of the plants.
Ive also found that when using really powerful UVA/UVB, that you can kill them, just like putting them in full sun, at the Equator, after starting them inside. So unless you start them under UVA/UVB, or you break them in, they will get burned up with these lights.
The Solacure is made for Plants.
The Solacure has a Built In Reflector, requires no special fixture, Runs T12, is also Overbuilt and will run from 21w-80w in certain applications.
The glass on the Solacure is patented, made in Germany, and is the best available for transmission of UVA/UVB.
But at 32w, the Flower Power bulb is a universe more powerful vs the 54w Dragon Bulb. The Solacure would be rated at 30%. vs 14% for the Dragon 54w vs 34w for the Solacure. But they don't rate them that way, as their bulbs have a different UVA/UVB combination that is specifically made for horticulture/plants.
They also make lighting for curing wood, aging guitar finishes ( Relicing ) and giving show pigs a tan.
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.
Again we licensed Sol Glass for this lamp, like our SG series lamps. It is more transparent to any other UV glass made, and allows transmission of UVB between 280nm and 300nm, something other lamps don't do well. This is one reason our lamps have been so successful in the labs, testing for resin/flavonoids/terpenes/THC. The new spectrum uses many of the same spectral peaks as the SG, but are 3 to 4 times stronger in the UVB, while still having a solid UVA profile. UVA is seldom discussed in many circles, and it is too large a topic to discuss here, but we design our lamps with a sun similar UVA spectrum because we have good reason to think it is also very beneficial for UV started plants. The UVA to UVB ratio is very different than the sun, however, as the effective ratio is about 4 times higher than the sun. This is why you can use half as many lamps and still get twice as much UVB. In short, you use few lamps farther from from your plants. This makes using them easier and cheaper for you, while being more effective. It is hard to overstate how big a leap this lamp is.
Like most Solacure lamps, the Flower Power has a built in reflector, so you don't need to worry about using reflective material with it. Mylar, white paint, all these absorb UV anyway, they are useless for reflecting it. The image on the left shows a regular lamp, the image on the right is how the Flower Power is designed, with an internal reflector. It forces all the light to go in one direction, making designing and installing a system much easier. This means the lamp has about 50% more total UV output than a non-reflector design with a home made reflector.
For all flowering plants (including fruits and vegetables) grown indoor or in a greenhouse environment. The exact amount of UV needed for each plant will vary, and must be determined by the grower. To offer enhanced UVB, most growers will use two of the Flower Power lamps for every 1000w HPS/MH or equivalent. Obviously these will work on cannabis and are designed to maximize the UVB needs of the buds, but it was designed to be a greenhouse light and to provide the missing UVB for any plant.
How to use these lamps
Use two Flower Power lamps per 1000w hood, one on each side for even coverage, 12" to 24" from the plants (farther is weaker so needs to be run longer, but covers a larger area). Run 1 to 4 times per day, 1 to 6 hours per cycle for up to 12 hours (single cycle). How much depends on your particular plants, so start with 2 to 4 hours and work your way up, looking out for burned edges. The goal is to stress the plants, push them, without damaging them. Only run during your day cycle. Use during flowering and fruiting stage. Also proven to suppress mold and mildew as well as discourage many insects.
Another method that is claimed to produce higher CBD is the "Pulse Method". You run them 15 minutes on, 45 minutes off. This will shorten lamp life somewhat, but will still get you 2 flowering seasons worth of use. These claims have been made by a few professional growers. Most tests that instead run the UVB continuously for several hours have shown to not dramatically affect CBD production (flat to slightly higher).
Already certified to get 20% to 35% higher THC and flavonoids and anecdotal evidence that approaches 40% higher, and results keep coming in.
