I saw a ton of those bulbs . Does the color matter ? I saw some that were orange and some that are purple .

It only covers the uvb , I’d assume I’d have to get a light for A as well ?SolarSystem® UVB

The ones I had got, looked warm in spectrum. I never got serious with it. Hung up a couple of bulbs and watched for anything happening. Nothing happened so I turned the page.

I see , I was worried about that . I was just looking at reviews for uvb light listed above and it looked promising . Gonna scoop that light . It’s on sale for 100$

I’ll def let you guys know. I’m a month away from flipping the switch to flower . Just getting everything together . From what I read it’s proven to be 20-30 percent effective . Well see .

Ive been thinking about this as well and I'm looking at these. I hear they're quite good covering range of UVB and UVA.

The Emerson Effect comes from adding Far Right or IR light and will increase the rate at which a plant grows. It does not boost resin production like UV.
UV light is added at the end of the flowering stage to increase resin production in buds. RapidLED and HLG both sell a add on light bar that supplies UVA.

Got ya , I thought the Emerson effect was the point of running uvb to create more resin / trich . Thanks for clarifying. The 2 companies listed are out of my budget. But the solar system uvb is within range .

Solacure is the only one that goes to 285nm, and activates the UVR8 gene.
The about 2ft light is 18w. No way it covers a 4 x 4 area. Id not buy that bulb. Overhype of product big time.
You need 2 4ft Solacure fo a 4 x 4 area, and run tham at 40w, 24in from canopy. Email the guy for best results. He answers all questions.

Thanks for the advice . Would it matter if I was only doing 3 plants ?

Not bad , just looking at their page . 129$ for a set up .

UVA is good for increasing trichome production. Lower spectrum UVB is used in short bursts to hurt the plant in a specific way which can increase the potency. The UVA light bar that HLG sells is meant to be run 12/12 during flower period, I have one in my current grow.

Actually, you can get the bulbs off of amazon or ebay and a t5 light strip even cheaper than that, depending on your needs. I got a 4 pack of the durolux 4 ft single t5 strips, and I'll daisy chain 2 of them together, then I'll run them with one of those "short time" timers for 3 min per hour to start. Be careful because these babies (solarcure too) can cook your girls with a quickness, so many horror stories around LOL. Oh and always use eye protection!!

If you want to cover a 4 x 4 area you need 2x 4ft bulbs at 24in. Start them out at 15 minutes every hour for 8 hours, and build up to 2-4 hours. If the bulbs are closer, reduce the exposure time. Main thing is to look for leaf stress, and then cut the lights back so its not stressed.
Trick is to give them all they can stand, and not damage them. And considering you have 600w at the wall, you about the same as a 1000w HID if you have the very best diodes. 100w HID, or equal, and 2x 4ft bulbs are whats recommended for a 4 x 4 area. You can easuily fill a 4 x 4 area with 3 plants if they are genetically capable, and you veg them long enough.
I run them starting from seedlings-flowering, not just the last few weeks. Ive seen them get burned doing that.
Theres also a technique of running them for a certain amount of time, turning tem off, and keep doing that for x amount of hours. But Ive not persued that aspect.
Generally in nature the sun is strongest from 10am-4pm, so 6 hours seems right to me to keep it simple.
Also more Sativa dominant plants will possibly react more, as they have evolved with high levels of UVA/B. Plants closer to the Equator.
Also high altitude., has higher UVA/B levels
from what little I know, UVA creates more physical trichomes, and UVB changes the chemical profile.
One could increase physical amounts of visiual trichomes, and still not change the profile to be more psychoactive. Activating the UVR8 gene, and also supplying UVA works together.
Also 1 question to ask is??
Does marijuana have the RUV8 Gene??? Simple question. Right??? Answer is Yes. Many plants have it. Tomatoes, flowers, veggies. Fruits
So it only makes logical sense to activate the gene as the sun would do, if one can get a light that can trigger that gene.
The proved way back in the 1973-74 in Skylab that the chemical profile of marijuana can be altered by using different light wave-lenghts.
Weed was one of, if not the first plant they tried to grow in space, and when the budded it, they flashed it with extremely strong levels of XENON, just for milliseconds, burning the buds, and they said it changed the chemical profile of the oil to keep it simple ( For Me ).
And to me its a no brainer to supply UVA/B if the plant gets it in nature, and the sun does go down to 280nm outside. I wouldnt go less than that for safety sake though, and kill the plant. 280nm is the line of UAB/UVC.
The article was in High Times
The manufacturer lists Perdue University, and University of Florida, Texas A&M as 3 examples of research labs that use their bulbs. Theyve also been making Non Plant Specific bulbs for Show Pigs, and curing wood since the 1980s. And NO I dont work for them. Satisfied Customer. I wish I did.
