Help me add UVB 10k to my last few weeks, open thoughts

[BigGreenHulk]

Hey gang,

I am looking to add some UVB to my last few weeks. I have a 5x5 , 6 site custom RDWC and a custom enclosed spydr with Co2. I have them nice and frosty and am looking to add one 4ft bulb right down the center line between the two rows. I would like to have it on a timer to turn on through out the day at 15 minute increments to stay on the safe side.

I have also just recently been told to look into a 10k finisher vs a uvb or perhaps both. Run uvb for two weeks and then replace the uvb for the 10k finisher. I am open though and thankful for your time.

So what are u wondering?

Red light in flower seems to be the new thing with QB lights, so good on that

No clue on why you would add the 10k

 

[BigGreenHulk]

I am wondering what other have done, if anyone has a suggestion that I am unaware of to help add UV-B to the room. What I have read/been told is that adding a 10k (blue spectrum ish) to the very end makes them "bug" out and the Trichome production gets kicked into overdrive.

You haven't heard of a 10k for finishing before today?

 

[Chris Scorpio]

Not me

I'm not a big believer of false hope claims

Maybe it's true, maybe not, but can't say any of the good growers I know have any added 10k lights, Red yes, but I could be wrong

But hey...go for it

I use terpinator to push more trics, that for sure works During Flowering

 

[BigGreenHulk]

Thanks man, I am pushing the terpinator myself and It should end well but I am always looking to learn more and more. I have a local friend who seems to make it look like xmas when he harvests. I mean the kief is crazy! And he finally said his secret is adding a 10k bulb at the end. So I thought I would ask and read some more on it.

 

[Chris Scorpio]

Do it then

What are yer lights now?

 

[BigGreenHulk]

Oh btw, this run I did add 4 far red leds I learned about from grow mouse and I have to say it really does do quite the trick for speeding things up by a few days/weeks

Currently is a spydr2p

 

[Chris Scorpio]

All I see is old info which mentioned 10k with hid or CMH lights

 

[BigGreenHulk]

hhm interesting, I appreciate you taking a look to help out..

This is the bulb that sparked my interest:
AgroMax 4 Foot T5 10000K FINISHER Bulb

 

[Chris Scorpio]

Spyder is a great light

 

[Chris Scorpio]

Does yer buddy use a CMH then
What lights he use

 

[BigGreenHulk]

he uses a spydr as well and quantum boards

I used to use 2 315s (CMH) but he converted me when we compared results

Here is the "finished" product of enclosing it and you can see the 4 far reds in there as well. It was a little tricky sealing it and getting the light to hover in between the top and bottom but I was able to get it done and it "floats" inside the enclosure

 

[Chris Scorpio]

How is he getting the 10k then

MIGRO does light testing and just posted vids on the uv spectrum. And tested some specific uv bulbs.

Thank you , I will look into this today. Do you have links by chance?

I have been watching these, they seem to be in the area I was looking to explore. Can you comment on growing before and after adding this to your regimen? Thanks a ton

I can't comment on the before or after, no. I've had UV of some sort on my grows. Granted it's not many, and I won't get to really test this bar out until this run (that will start in a week or so) flowers. I'm redoing my grow space and upping my game, and this bar was one of those additions. Was using reptile bulbs before.

What I like about the package is it's coverage. It's good for like a 4x4 or 5x5 area. Granted it's UVB and you don't need much, but nice to know that it's well dispersed. The other thing I like is the size. It's narrow enough to fit between the strips on my big light, or in between the two new Budget LED panels I have coming. It works a treat for me and the price isn't bad, all things considered.

Replacement bulbs are half the cost, but it's used so little anyway, it will last a good long time.

After a few weeks of reading and researching I made the decision today. I went with the Hortilux power veg (its full spectrum) with uv. Looks amazing and I am looking forward to the results of added Uv-b. Will update along the way for those who may also be researching or are just curious.

It complements the spydr 2p spectrum quite well I would say. Implemented today, one 48" right down the center at about 10" above canopy.. I was torn to use or not to use the reflector. As I wanted it to spread out wider rather than being focused more in a direct downward direction, but I am still on the fence.

I introduced it today at intervals of 15 min once an hour for hours 2 through 11 of the 12 hr cycle. After day one of inspection, I noticed only two leaves that had the slightest brown tip on one blade of the leaf. I will continue this strength for a few days as I acclimate them up to higher doses as it gets closer and closer to the end which I am speculating about 3 weeks.

Here is the spydr spectrum, You can see that the t5 bulb I chose really complements the spectrum I do believe.
