Torsti

Whazzup´s Krono´s beneath 540 watt T5 fluo´s

Recommended Posts

 

After a lot off opinions about good reflective material on the walls, i decided to make a box where i could measure the difference in reflection between the various materials.

This box only measures the reflectived amount off light where the sensor off the luxmeter has no direct light to get a correct idea.

 

 

... the thinnest mirrors had an better reflection ( less absorbtion?) than thicker ones.

 

 

great tool, congratulations for doing this!

of course mirrors are the best way (i think), but this 'compare test' is a real "+" for all of us.

nota : the less thick a mirror is, the less glass is present to absorb photons.

what could be interesting too is to know what kind of color is less absorbed/more reflected, if there is a difference.

a look on "wiki"about glass(es) can answer perhaps...

Dear Growers,

an update:

On this moment not much happened.

The girls are growing slowly. :wacko:

But here are the pics from yesterday:

gallery_5351_15237_134050.jpg

The girls still have a lot of the three-vingered-leaves,

that´s the reason why I´am still waiting with turning the clock on 12 /12.

gallery_5351_15237_47228.jpg

 

Maybe that I´ll set the clock next friday on 12/12.

 

Last friday the girls got 15 liters to drink :

15 liters water with 20 ml Connoisseur A and B each and all boosters / goodies.

 

A little bit about my thougts over reflections:

A few years ago, there was a discussion on Wietforum about the best reflective material for the walls.

The growers were talking about white walls or other diffuse reflective materials, but nobody had ever tried mirrors.

" The glas of the mirrors will hold back too much light, not worth to try it!"

 

But is on this forum one grower, who will shave in front of a white wall? Because reflects much better!

I won´t try it! Too many cuts in my face.

 

The leaves of our plants can only uses the light wich comes from above and light from beneath will be worthless to the leaves.

Also, I don´t need to lighten up my filter, my lamps or the roof of my cabinet. I want all the light on the plants!

 

I was starting with this underlayment-stuff:

gallery_5351_7758_402198.jpg

Later I`ve done a first few rounds with plastic mirrors:

gallery_5351_11532_375887.jpg

These plastic mirrors were reflecting very well, but as you can see, the mirrors aren´t so good.

But the yield was getting better with this mirrors.

These mirrors where difficult to clean, with abrasive cleaners or strong cleaners the mirrors were loosing their

reflection.

So, I´ve got to change to beter material.

Real mirrors, two mm thick!

gallery_5351_9678_311910.jpg

 

With this mirrors, the yield is getting higher again.

But this mirrors don´t warm up and all of the heat had to get ventilated away,

The air was, my thoughts, 3-4°C warmer now.

This mirrors are to clean up with every goed cleaner without loosing reflection-power.

I´am very happy about, that I´ve made this step.

 

Measurements in my cabinet.

I´ve made some measurements in my cabinet with different reflective materials:

gallery_5351_7579_403110.jpg

The temperature of the tubes were 60°C (temperature is an issue for the tubes) and the distance to the sensor was 80 cm`s.

The grid is 10 x 10 cm.

 

Black-and white-foil (white side):

The measurement

gallery_5351_7579_23297.jpg

Result: 28800 lumen

The spreading:

gallery_5351_7579_5723.jpg

 

Plastic-Mirror:

gallery_5351_7579_27042.jpg

Result: 34031 lumen

The spreading:

gallery_5351_7579_13948.jpg

 

And now the real mirror, 2mm thickness:

Measurement:

gallery_5351_13388_40272.jpg

 

Result: 42950 lumen

 

The spreading:

gallery_5351_13388_7829.jpg

 

There are hanging now 44500 lumen above the plants, and with this reflection I´am able to get nearly 43.000 lumens on the plants.

So, I think this is the best reflective material.

If there are any more questions, ask them!

 

@Robogro,

normally, you can buy these mirrors at every flatglas-dealer.

If you don´t find a dealer, send me a pm.

We´ve got someone on WF.

 

@Smudger,

are you sure? :icecream:

 

@Wrecks,

thank you! :)

 

@Whazzup,

done!

 

@Dharmabum,

there´s a problem with the Lightwaves and also with the Badboy.

They´ve got a close reflector, the warmth cannot get up.

I´am just building another lamp for Secret Jardin 120 x 240 cm:

This is one lamp for 120 x 120 cm.

gallery_5351_15237_963259.jpg

That are 12 tubes of 54 watt, the distance from center to center of the tubes are 8 cm.

The warmth can go through the reflectors.

 

@Ikke,

nothing to be sorry about!

My topic´s are always free for information. :rolleyes:

 

@Rollit,

You´re right, that´s the reason why we´re using 2mm-mirrors:

gallery_5351_15237_155350.jpg

Here you can see the mirror on the fixed on the door of my cab.

 

@Smudger,

the only special of this mirrors are their thickness.

For the rest are these standard mirrors.

 

Greetings

Torsti

@Torsti Nice info and thanks for input. Do you make these panels on your own? I catch your drift with the commercial panels being enclosed,but won't a oscillating fan moving over the plants be sufficient to get rid of excess warmth? Maybe not in a mirrorcloset,but for example in a dr120? I learn alot about the use of mirrors and the approprate thickness! I always heard mirrors eat light,but i see now it has to do with what kind of mirrors are being used....Very interesting thread!!

Well Torsti you have changed my mind on mirrors that's for sure.

 

A really informative and detailed explanation.

 

Thank you :)

I love the look, and the science behind it sounds legit, but I've always heard that mirrors reflect back green and yellow, while absorbing red, infra-red, ultra-violet, and blue light. Regardless, those are some beautiful plants!

Dear Growesr,

a short update:

Situation at 28-01:

gallery_5351_15237_96213.jpg

gallery_5351_15237_123244.jpg

I don´t understand why, but all the plants have only 3-finger-leafs. :(

This is a grow I´am not exspecting a goed result.

 

Situation 30-01:

gallery_5351_15237_172703.jpg

gallery_5351_15237_204402.jpg

Wednesday, the girls got something to drink:

15 liters water with each 10 ml Connoisseur A and B.

Tomorrow the girls are gatting 12/12 lightregime, starting up the bloom.

I´am really not knowing what to do, the most growers will say stop that round and start again.

But, it´s just for mij oil!

 

@Dharmabum,

yes, I build this panels on my own. The most producers of fluo-grow-lights don´t understand how this lamps work and they give a shit

about it. Let ik look nice and it´ll sells. If it dont work, they don´t matter.

This is the first half of the lamp for a Secret Jardin 120 x 240.

With a close reflector and a big light-unit, you´ve got no chance to get the heat away.

 

@Smudger,

try mirrors and you´ll see! :jump:

@youngsta,

take a look at the pic´s. Here you can see wich colour got lost first.

Remember, the light is only going one way through the mirrors and reach the plant.

The lost of colours is not worth to talk about it.

UV-light will be terminated by the mirrors.

 

@Robogro,

you´re welcome! ( Wie immer!)

 

@WezielDeziel,

you´re welcome!

If you´re working with mirrors, the temperature wil rise,

but for the rest..... you´ll see!

 

Greetings

Torsti

Dear Growers,

the update:

The situation this evening:

gallery_5351_15237_192877.jpg

gallery_5351_15237_171013.jpg

The ladies are growing and the the roots are comming out of the pots.

Tonight the ladies got something to drink,

15 liters water with 10 ml Coonoisseur A and B each plus al the boosters.

 

Tomorrow the lights will get switched to 12/12.

Otherwise the plants are getting too long. :wacko:

 

@plasma,

amazing is another thing.

These plants have 3-vinger-leafs, that´s not so good.

But in this, they´re well uniform! :innocent:

Hi torsti,

 

I'm sorry for your grow issue, even most of growers would enjoy to have such minor kind, but it is really interesting otherwise (let's try to see the glass half full :P )

Strange like all clones have same reaction. 100% ? Have this clone been grown by somebody else, or you formerly ?.

 

But I will continue at this time, in about 10/15 days, after flower formation, you'll be fix if you was right or not :)

 

Thanks for reporting, have a good week ;)

and today:

gallery_5351_15237_246735.jpg

The first hairs are coming and the smell is coming, too:

gallery_5351_15237_11773.jpg

It´s started. :rolleyes:

 

@LaVieEnRose,

this cutting where made bij myself.

All the plants have this reaction.

I´am continueing the grow,

why stopping, it´s just for my oil. :yummy:

 

@Aws1,

you´re welcome!

Enjoy this grow: :tu

 

@Whazzup,

I´ll do my best.

It could be difficult, but I hope to keep this ladies beneath 70 cm.

There are a lot of tricks I can use, B)

don't worry about the leafs, it's not a sign of a bad yield in this case i think.

i'm not sure what is the cause of this kind of "problem" but i've never have yield problem when it happens.

it certainly due to a "pre-flow". perhaps during the transport!? i don't know all there history...

don't loose time, it's gonna be great i think! ;)

p.s : i see your answer. so, no transport or another cause of light-less situation...!?

great stems though ;)

 

yes, it seems most important than a few fingers leafs case, isn't it?! :jump:

 

well, what's in my mind :

your plants look like they were re-vegeted. the thing i make in this case is to cut the "gourmands" and just let the new(s) nodes. with it, the flo' hormones are getting away with the old leafs and branches ans don't disturb the new grow stage.

but without doing it you could have a quicker (and probably a better) yield.

that's what i've observed but nothing scientist, only personnal. so, if somebody can contradict or confirm that, i'll be glad...

gallery_5351_15237_223622.jpg

Nice white roots. :)

The length of the girls, they´re still growing.

Maybee, that this will be the biggest problem of this grow: :wacko:

The lamp is still hanging on the same place as on the first day..

gallery_5351_15237_245285.jpg

 

The today´s-situation:

gallery_5351_15237_106692.jpg

gallery_5351_15237_144567.jpg

The girls where jumping in the last 24 hours..

I hoop that I can keep this girls short. <_<

 

@Rollit,

I´am not worrying about the leafs.

A part of the genetic´s of this plant is haze, the cuttings of the haze can´t stand against 24 hours of light.

This cuttings are not revegging.

 

@Whazzup,

they´ve got a nice length, too (until now) :innocent:

Let´s wait and see what will happen.

Dear Growers,

the update of day 5 (Blooming):

The girls where growing a lot in the past 24 hours :

The lamp is still hanging on the same height as in the beginning!

gallery_5351_15237_155836.jpg

gallery_5351_15237_188768.jpg

The leaftips are reaching now the reflectors. :wacko:

 

Tomorrow I ´ll clean up the plants.

There are too much buds in the deep, wich wouldn´t develop well,

so I´ll cut them of:

gallery_5351_15237_277563.jpg

So, I´ll be a little bit busy. :rolleyes2:

looks great! i think he meant 3 leaves as were the clones from a revegged plant. 3 leaves is a sign of stress for sure but not critical.

 

i have seen this in many of reveged plants. like you said, cut the tops and new growth should be good if the environment is good. of course this is not good for SOG...

 

i can testify to how my badboy T5 traps heat. i drillee extra holes in mine to help evac the buildup. and i have two 6inch booster fans for exhaust - 1 was not enough.

 

i would love a DIY to make my own light next time. i figure it must not be that difficult... could you run us through your build / thought process why you make yours how you do? thanks

 

keep up the great pics

hay torsti nice pics dude, second round or more for you now.?

Dear Growers,

the update:

This evening I´shaved the legs from the girls. Now they´re nice and smooth. ;)

I´d liked to see it in another way, but the first 5 cm´s where filled up with little buds and leafs.

gallery_5351_15237_17450.jpg

The girls also got something to drink tonight:

15 liters of water with 10 ml Connoisseur A and B each and the boosters following the schedule of the third week..

gallery_5351_15237_185823.jpg

 

I´am curios about what will happen next. B)

 

@Thesamyboy,

the reflector of the Badboy is a part of the stability, but you can change this reflector against normal T5-Reflectors.

Then you´ve got it open and the warmth can get up.

In this moment I´am very busy with family-affairs. But when I find the time I´ll open a nieuw topic whith building a lamp.

Give mee some time. :innocent:

 

@Inkog,

i like the nutrients of AN.

It´s expensive but I´ve got some good results with it.

The use of it is very easy and it´s mixing very easy.

I don´t need to look on my pH and it works well.
