Lighting Anyone using UVB supplementation to their LED/COB LED??

[Mariano Gomes]

Hi there,

(sorry for my broken engrish)

I was growing critical + (photo) from dinafem seeds over 1 year (clones only, SOG).
I have a digital ballast and used dual spectrum hps's (250-400-600 watt) in a cooltube (80 cm x 80 cm tent). Plus, added sometimes 8 x t5ho's (55 watt each, 2700k, 6500k), or 4 x 80 watt cfls, smd leds etc. I was never growing something else than critical + (due to location problems) and cloned that one seed like there is no tomorrow. All i want to say, is, everything changed after i get osram ultra vitalux 300 watt uva / uvb lamp. Last batch i growed was under 250 watt hps (cooltubed) + osram vitalux 15 min x 6 per day. I never smoked something like that before in my growing carrier. I have maybe over 20 runs under my belt (perpetual), but that one was the real killer. I made some space cakes and i really needed someone to help me to come down. I was high almost over 2 days. (growing not so long, but smoking over 15 years inc cakes and stuff )

Now i am building a COB setup (5 x 40 watts 3000k), with some smd leds (smd 4014, 240 leds per meter x 5,120 watt, 6500k) and 2 x osram ultra vitalux for 2 autoflowers. I will never grow without uvbs again. Hope this helps.

I found this blog after reading your post where he just turns the uvb lights on the entire grow. The osram is 300w he used reptile t5 lights like this Amazon product ASIN B00AQU8H1S

Hi mate,

this is exactly what i was thinking:

''The difference in potency is so obvious that all my patients would complain about the lack of potency on the crops that I did not use the UVA UVB lighting!''

When i was checking trichs, i couldnt believe my eyes, i never seen so much trichs together, bounded, it was like uhm afro hair style. Like this but imagine it total covered with trichs (no greenies)

This bulb is very powerful. I wouldn't run it for 12 hours. Besides, it may fry plants, if not, 300 watt is too expensive to run imho. I think, i will get another one and will let em run for just 15 min x 4 (2 hours x 300 watt) Even 30 min per day is enough.

These bulbs used for

• Sunlight simulation
• Glue curing
• Artificial material aging
• Exposure of UV-sensitive photoresist coatings
• Terrariums (big sized)
• Equine solaria.

So reptile bulbs are like toys if you want to compare em. Be warned. Be save.

yeah i was thinking bout the reptile bulbs cus it's cheaper. so if i just need to run 30 minutes per plant minimum per day I can just buy 1 lamp and move it around...... would that work? or should i do 1 hoour per plant per day? and do you do this start of veg till flower or just in flower? I think you should start a thread about this not a lot of people are running uvb.

I used it just on clones, started 2 weeks after 12/12. Well, i never had something else than critical + clones'^^. And clones direct to 12/12 after they get rooted. Perpetual thing. in n out

Now i am growing 3 autos under cobs. They are 2 weeks old (seedlings).The bulb is extreme powerful and i dont see any reason to stress them out (or fry them).

UVB is not safe. You dont even have to be in the same room when its on. I wouldnt mess with moving it around. Just put it on a timer and forget it and leave it for now if its expensive. Better be save

If ever I do buy it in the future will one light be enough for 2 plants in a 4 x 4? or would I need 1 light each?

AgroMax Pure UV the best UVB/UVA lamp you can get! Don't grow without it. I buy mine on Amazon.

How many would you put in a 4 x 4 i am planning to get the hlg 600 quantum board its kind of huge smack dab in the middle. So I was thinking like 1 4 foot t5 per side of the quantum board? would that work? what would be ideal for my setup? How long do you run yours whenever the light are on? during veg and flower?

I use 1 in a 4'x6'x8' space with Orca Grow film walls.
