M_EVO_LUTION ** SideMevO ** ALL THE ROADS LEAD TO ROME ** DIY LED PROJECT

Hi RIU, how's yr sticky stinky life?

I am jubiARE, a little experience grower and diyer of LED arrays. Some of you know me anyway..

I am back after some time out of the game; My last grow turned out a dead affair after a vacation. And the one before too!

You can imagine the frustration, so I had some time out and dedicated myself to my profession and my Family.

I have something going now, I began to flower 3ish weeks ago?

I named my arrays Mevo, from evo Led, that has inspired me amongst others for the design. I do not intend to compete with evo or

sell my arrays or anything like that, it's just a funny name (Actually nicolaj06 inspired me for the use of aluminum rectangular tubes)

Anyway, as I always say, everything was possible only with the teachings and contributions of the Master of LED's Knnabinoide.

Whoever doesn't acknowledge that, is a liar or a clown. Or simply, he hasn't gone that route, and in fact his arrays are of inferior

quality. Or, if he is on the right direction, it'll take him a couple of years to get him start where Knna left. Simple as that.

I am not saying it all can't get surpassed, it's about time actually! But I am yet to see any tangible proofs of that. So, due to my

failures lately being unable to even test Mevo1, I have gone a "safe" route for Mevo2.

Anyhow, I am not to be the genius here .. but I should def sense one. I am a guy like you there, with little electronic capabilities.

I am a learner.

Ok, this is the scratch Mevo2 idea here:
It's a side array thought for fitting in the most common grow tent

IMG_20121017_152248.jpg

Again, this is following the teachingS of Knna; Instead of packing the roof area of so close together

diodes and modules ..... HIT THE PLANTS FROM THE SIDES

IMG_20121022_162153.jpgIMG_20121022_162211.jpg


as you can see there is an addition to the original mevo rectangular tube design: I glued some heatsinks on the back

(for extra cooling capabilities). I don't believe in no noisy fans.

Sorry I have to go now, more on it and pics and all tomo!

Thanks for looking

Looking great! I was trying to achieve a nice thermal management solution using bolts and a cheap aluminum dish, but it didn't work out very well for several reasons. Looking forward for the specs and colormix, I'm very curious!

This is a pic showing the making of the array. Diodes are spaced about 2" apart from each other

Specs:

24 Golden Dragon Plus Hyper Red 660nm bin T1 (Lowest possible I am afraid)
24 Cree XP-E Red 620/30nm bin P3 rated 73.9 flux @350mA (best possible to date)
4 Cre xp-e Royal Blue top bin 500mW top bin
8 Cree xp-e warm white 2700k top bin Q4 100 min. flux

They are all mounted on good stars glued to the heatsing by Arctic silver 2part thermal adhesive

The GD+ are attached to the star by the same Arctic Silver
The Cree xp-e are reflow soldered utilizing the "Iron plate" method (thanks to the diyer friends over at Aquarium forums)
It is amazing how pretty easy that is! Do not be afraid of reflow soldering at all!

The reds are driven @500mA by two drivers: (roughly) 2.25v X 48 = 108v X 0.500 = 54Watts
The W/B are driven @650mA by one driver: (roughly) 3.4v X 12 = 40.8 X 0.650 = 26.52Watts
We have about 80Watts in total.

more to come
Thanks

Welcome back Jubiare!!!!!!!!!!!!!!!!!!!!!!!!!!!! Looks like you've been busy........Ah mevo2 seems to be quite an "evo"lution from The first:p.....don't worry I still don't think our spanish friends will sue you:) their busy repairing their starlight panels...ha


good to have you back.......subbed........let's do this spaniard!!!

Thanking Enduroxx, actually I'll go over his thread and rep him, I got the input of supersoil;
Maybe a change was needed anyway, given my recent failures?
I still don't know what to really think of coco as media, maybe problems associated with the quality of my water?
Stubbornly enough, I used coco instead of peat/soil .... so that's supercoco!

I know there is a thread test of some supercoco and that person has been banned or something, well this is only a coincidence that I am experimenting with coco!

I didin't want to use products from the animal slaughtering industry, so I worked out some amendments myself (not ideal, better follow the recipe at first!). My thing is something in between lc's mix, supersoil mix and 3lb etc.

base mix for germination/seedlings:

5 part coco
2 part EWC
3 PARTS perlite
1/2 tbsp dolomite limestone p gallon

veg/flower amendments (p/gallon):

1tbsp alfalfa meal
1tbsp kelp meal
1tbsp comfrey meal (from pellets form)
1tbsp fish blood and bone (6 - 6 - 6)
1tbsp bat guano (3 - 14 - 2)
1tbsp coffee grounds
1/2 tbsp granite dust
1 tbsp zeolite
1 tbsp rock phospate
1/2 tbsp granite dust

***it's an experiment and things need to be dialed in***

IMG_20121025_122342.jpg

4plants were vegged under the sole mevo1, 2were males. Mevo2 added when beginning flowering
I was using one half of the panels so one reds driver was switched off.
Too cold and two weeks ago I switched it all up

more to come
Thanks

The soil mix seems good. Like you said, just got to dial it in. or, maybe thats more the additives/nutrients during veg/flower aye...

I think the shape of M_EVO_2 is perfect for the shape of your room. :)

hey dnl.svrr thanks! Don't give up on yr project, I have personally gone with knna recommendations for heatsink dissipating area: 21 sq/inch for every watt burned (no fans). He used to say you need a min. of 9 sq/inch for every watt burned utilizing fans. Bolts? You mean stars bolted to heatsink? That gives you the best thermal transferability if you employ a decent (mandatory) paste

Thanks Psuagro!!! You mean busy with Mevo, well I had a good month off everything but busy ever since yes! Mevolution is all about the cree xpe and the extra heatsink ... well thye spectrum changes slightly too. Most importantly mevo2 is more potent in photons!

Not stupid, too clever maybe? You don't seem to care so there's nothing to get. Or just look at the pics where there's a smaller heatsink with fins attached to the heatsink body

Hi Kool nice to have you around, thanks for the heads up. Soil mix seems pretty decent innit? I had some burning at first with some underdeveloped plants ..... Rome is the one that responded nicely. Maybe some macro's were in excess? I am not really adding anything for now apart from ACT's. Yes mevo2 fits a 4 feet tent nicely

Hey Brother Welcome Back :clap:Im Subbed Up For The MEVO2 Grow :bigjoint:

Thanks Bro, yeah pull up a chair there's gonna be some meds out of this time ... for sure! (which I need)

____________________________________

Rome is my baby; She has done well compared to her sisters/brothers (two were males). She's a NextGenSeeds.
She was fimmed at 3 weeks, she responded well. This pic is at around middle of 3rd week of flowering
SNC10181.jpg

Trouble is trouble eh (timewrap NextGenSeeds). She was fimmed at 4weeks, she responded poorly exibiting deformed leaves. She was also burned at first by the hot mix anyway. There has been other issues maybe about ph but I am not sure. I don't care much about her to be honest, but she is staying in. This pic is at middle of 3rd week flower, she is doing some better now I'll show you a pic next time!

SNC10182.jpg

I am running around 160w of LEDs but 30% of both panels don't really hit any plant. My temps are not ideal, it's cold here those days; I am extracting air on a timer 30mins off / 15mins on, to keep them warmer!
I don't ph water anymore, but I notice that a weak act works better than plain water.
I am rotating adjusting heights on a regular basis in an attempt to make the most out of Rome, she is filling out nicely actually!

Happy growing everyone!

whazzup puff thanks, hope all is sound with you!

OK so we are jumping up to real time here in the MEvo room 5 1/2 weeks flowering:

Yesterday I fed the girls with a AACT:

10ml Guano 3/12/2
10ml alfalfa
10ml kelp meal
50ml EWC
6ml humates
X two gallon of water


SNC10214.jpg

SNC10198.jpg
SNC10203.jpg

That's Rome! I am really pleased with the organic amendments method! Can't wait to have a taste!:weed:

Sorry I haven't got a proper pic of Trouble the retarded:o

thanks for stopping by I hope you and yr girls are doing just fine

Hey RIU here a quick update about Rome and Trouble the retarded.

Wish I had two or three plants like Rome they would fit just nicely between the MEvo's!

Actually Mevo1 has failed half of the reds, maybe the driver? I haven't got time for this to fix right now!


SNC10225.jpg
SNC10229.jpg
I am watering them separately, Rome is thirsty, Trouble not really!

Water is never plain water, last time it was:

AACT
Two gallon of water
Handfull of worm castings
10ml kelp meal

happy growing everyone

Hey alien foreverfly how u doin? You must know that UFO's exist than? About time they'll come to us and teach us something about human beings .... we are aliens to it at times. For the time being I'll do with the MEvo spaceships than;-)

Hey Psuafriend thanks for yr interesting interest ah! Well, han's got 29 reds x 4 blue? I got 42 reds x 4 blue. But mind, I have 8 Warm whites, and I don't drive the reds at 700 but 500! Which is more efficient yes, but I need a slightly higher number of them. So, all in all ... it is red dominant spectrum but not as much as compared to some others. knna would be proud of me? He used to say, don't get warm whites, they are not as efficient as neutrals or cools ... but I wanted more FR! ... I am proud of him for sure;-) I have taken a few pics for you vvv

Second.....

Also, at what point did you start hitting them with all that red?

Hi there, I started using the sideMEvo panel just at the beginning of flowering. I was vegging with this:




10white/blue: 3.3v x 10 = 33v x 0.500 = 16.5w
16reds: 2.25 x 16 = 36v x 0.500 = 18w

That was for less than a month, four plants from seed (I added one and than two 20w cfl's for better temps).

I than swapped over to MEvo1 (experiment; different spectrums at different length of the panel. I never had a chance to experiment with it as my previous grows failed). Diodes are not as efficient as sideMEvo

I love the KNNA LED + organic soil combo. That is the cutting edge for med grade cannabis. Did you ever figure out why the red string went out?

I have been working on a new KNNA style LED using XT-E and Luxeon ES. The old ones (golden dragon+) have been kicking butt for vegging saving a ton of electricity.

Well said on the organic + Led = med grade mj!

Interested in yr new project give us more details that'll be nice! (even open a thead or something)

..I haven't solved on the failed diodes .. can't be bothered right now .. actually I did test the diodes as soon as that happened .. they seemed to be ok .. so I suspect a driver failure .. I have the driver but I can't be bothered right now hihi:neutral::roll::eyesmoke:
