UVB Supplemental Lights

[Tictok]

I run Voost Led throughout now. For everything. They have 350-450 nm UV as standard. So it's always on.

I've gradually replaced everything for Voost, so one in the 2 x 2 for veg and two in the 2 x 4. The value for money is incredible and they are bombproof.

UVB is 280 -315nm

Only needs to be run for a few hours a day last 3 weeks flower.

Bit of info on the UVB @Marcus

I'll try and have a listen later cheers.

From what I can find, UVB LEDs are quite expensive I found some 280 and 300 nm strips with a dozen LEDs on them, pulling about 30W... £1500!!!!!

Yup, £1500.

I think this is why LED companies sell T5s alongside the led units as it's more cost effective for everyone.

Did you buy your UVB direct from Migro @Treetrunk ? WHat were the import costs like???

Fair. Everyday's a school day. What are the benefits of the uvb at such a short period?

UVB damages cells, but the thinking behind blasting plants with UVB is that they produce more of their natural defence...trichomes and stalks full of sticky goodness.

So I think there's a balancing act between too much UVB = killing the plants and just enough UVB = more of that trichome stuff that gets you high.

I'm just dipping into it, but it seems about 3 hours in the middle of lights on time and aboout 3 feet away is the current internet science.

My issue is, I don;t and won't have 3 feet headroom in this cubby, so I'm trying to work out if I use lower powered UVB bulbs I can get them close enough to do their job without costing me too much in the electrickery £££...



I'd be all over these units if I was in the USofAyyyyyyyyyyyy. Adjustable spectrum n stuff!

Very nice, cheers for the info.

Holy sh*t they are pricey, I'll pass on the gift, would a readers digest subscriptiom suffice? Perhaps romance novels?!

Not on subscription. That's under the counter shit. 'Readers Digest After Midnight' I think they call it.

I think the light was about £85 with import duty.
The Migro cover's 1.2m. Reflective walls don't deflect UVB.
I have mine on for 2 hours mid light cycle for the last 3 weeks. Light height is about 18 inch away.
The other problem with the LEDs isn't only cost it's the efficiency. You would need loads to match a tube.

Yeh thats what I was thinking, the Invisible Sun LEDs will be expensive and you need multiple units (probably). If I can cover 1.2m squared with a 4ft tube for around £80 I don't think the LEDs are gonna compete with that price if I'm honest

@Marcus What do you think of these? Doesn't say anything on the site about UVA/UVB

Dunno dude, the more I looked into it, the more I looked into LEDs and the more I decided to stick with CMH.

I wanna see Bugbees grow room. I bet it's full of lettuce.

so do the little CFL types that kick out 10% UVB for reptiles work just as well as these 75% UVB and 25% UVA ones?

Never used the strip t-5 or t-8 typo uvb/a lights but ive used 3 x cfl lights stuck in cheap separate clip on light fittings. Not sure they did anything or not, i still have them in a draw somewhere and they may come out again at some point.

I ran them for last 3 weeks of bloom set about 1ft above canopy for around 8hours a day if memory serves me right.

Ebay do some great Arcadia t-5 kits for £50 to £80. I`m sure that ive read the t-5 are best overall and more economical and more intense than t-8. Pretty sure tis 280 -290nm perfect light spec for added potency .https://www.ebay.co.uk/sch/i.html?_from ... t=0&_sop=1

Out of interest the hydro store that advertises on gr420 do a decent t-8 uvb supplements same make as TT`s Migro for £110. https://hydro-urban.co.uk/product/migro ... cent-tube/

LED uv light isnt worth a wank for added potency is totally wrong light spectrum, well it was last i looked.
