Spectra Unit 90watt Led grow, almost done.Whe got buds...

Great looking grow with only a 90 watt LED...wow...keep the info and pic's coming...very informative. Looking forward to seeing higher power LED units results...

Awesome thread.... thanks for posting

You are bringing new light to a very dim subject.
Thank you very much.

way to ttake one for the team and actually do a legit grow with led lighting. they are looking surprisingly good! keep us posted! btw what was the price for that 90watt? and how high of wattage do they run? and is 90watt of led a cause a heat problem?

definitaly impressive i just recently traded my light for some beans it was a 45 watt grow panel. the 45 was only good for small stuff looks like yours worked just fine though nice grow man keep it up

Very nice. You've shown that with some seeds, pots, soil, pH kit, filter/fan/ducting, an LED light, light timer, $15 electricity (total light use for entire 2.5 months), and some good ol' tap water, anyone can grow some fairly decent weed in 2.5 months with minimal effort. No nutrients even! Well done. +rep

You probably would have yielded even more if you had gone with one specific strain... even plant height means you can keep the light closer to the plants, and we all know: Closer = Stronger.

I've been working on an LED project of my own, and I hope to be growing soon. https://www.rollitup.org/indoor-growing/186051-my-lighting-project-will-custom.html

I got the led, lol, but here to compliment you on the use of the CO2 tabs. I just found them at the hydro store and they are a serious peice of work, they look like. 1600 ppm for like 8 hours! That is the low budget solutuon I need for summer. reps.

I'm very sory I left you guys n girlls hanging just before the harfest.
Well i'm very pleased to tel and show you all that the 19plants came up with a total of 108grams , like more than 1gram per Watt!! here's a bunsh a pictures form the last weeks, and potpron of some of the stash. More pic's and detailed smoke reports will follow. thnx for all your awesome coments and suport...

Well.. this wasn't the end of things,, I went on with a totaly new LED setup, the SPECTRA UNIT 300Watt. I mounted two of them in me tent. here's the report...
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

I had already rooted some different sorts in veg under the 90Watt blue UFO light. I kept them in 24/0hr regiem so they stay small as possible.
Now I planted them al in bigger pots, some of them still not bigg enough but that will happen soon enough to. And placed them all under two 300Watt LED light.

This 300Watt LED Spectra Unit got like 8 different colours, plus UV-A and Infrared.

I'll keep them in veg(18/6) for a week or two, maby tree, we'll see how they go.

In about one week I'll plant the ones in 3,5Lite rpots to bigger one, like 11 Liters orso. There all in LAVA soill. Didn't gave them any nutes or stimulators just clear water, pH 5,8.
This little tottler is a Fruit Spirit from Royal Queen.
'

Lets introduce the ladys, their in total of 21, some are in pare, others in threesome and some are alone.
The first one is Berry Blaster. indica dominant. Regular seeds.

Bluemistic, Fem

Critical, Fem

Fruit Spirrit, Fem

Laotian Haze, (Thai) regular seeds (outdoor)

Lemon Skunk, Fem

Northenlight, Fem

PowerFlower, Fem

Skunk#1, Fem

Extra info:
Photo periode, 18/6.
Tempereture Lights on, 27,7 degrees Celcius. - Lights of, 20,3 derees Celcius.
Humidity: max60%/ min25%

Here they are 11 days into veg, under the 600Watt LED setup.. I gave m some Soillbooster from B'cuzz. Just to keep the soil alive during the veg and on.. Lateron I'll give m some B cuzz soil nutes. just a litle bit. Their all healthy and happy, on some of them I cound 11 fingers on a leaf.
Most of the plants are topped or fimmed. Here's a bunch of pictures.
11 days into veg(18/6) I water them every day. pH 5,8-5,9

In the background you can see the ''Laotian Haze''(outdoor Thai), she rizes above them all. I topped those a couple of days ago, unstoppeble growth. I think I have to top her again also her branches. In front are other, but smaller, Sativa dominant strains.

Fimmed ''Power Flower''

Topped ''Berry Blaster''

Big leaves of the ''Laotian Haze''

All the indica dominant strains are on the right side of course..

I'm gonna give 'm an other 10 days veg. See what happens.....

the Laotian haze is growing oke , not to fast, and I must say I think the internodes are decent for a 100% sativa Thai.

But the other Laotian Haze wer growin much to fast to big, so I pulled them back whit a wire.

Couple of days later the branches found their way back up into the light again.

A overal look

I nodest that some big leaves showed signes that they need more oxygen, to give'm hat they want I moutned a extra fan in the air intake.
this fan blows lots of oxygen into the tent.

its all going great. Except for the Laotion Haze, all the plants are in flower.
Every day I water them, like 4litre for all the plants. pH 5,8
The temp was 29C max./ 20C min. , LV. 63% max./ 18%min.
You probebly seen it yourselfs on a couple of the pictures that the Bcuzz nutes poisiond some of the sativa strains, it probebly is to strong or something, So I swiched nutes, once a week I give them ''Hypro Outdoor''. but only 25% of what I would give them normaly (600Watt HPS).
Every two days I shower them with luke warm wather. pH 6,5
Next pictures are, 1 week 12/12.



after 10 days 12/12


after 20 days 12/12

No signs of flower yet, with two of the laotian haze thai

except for this one, she turned out to be a male.

Some of the other plants at 20days 12/12







I cut away the lower branches so al the energy wil go the the more importend parts of the plants. Now its open between the plants so plenty of oxygen/C02 can get to the plants, even in the midle.




Fresh pic's, After 26days 12/12, its all good with the girls under the spectra units.











I'm very pleaced with the Hy-pro nutes , they seem to love it, judging by the looks of them..


sheers & grtz from Amsterdamp..

+ rep. I freaked when I got a ph prob after cloning and went right to my trusted 400 watt mh. Lol. So good job. I had the led UFO. Already to keep that up I had to spend another 200$ on fans and hoods.

arent those like 600 bucks?

but if this is legit damn LEDs have come a long way

however the 1200 u spend on lights could have been used more efficiently.

but in terms of you grow it looks great and thanks for being the pioneer with these lights.

nice setup man!
keep us updated on the fattylicous colas!

Thnx dudes, awesome coments..
32 Days into flower. They get 25ml Hy-pro Terra mixed with 10litre water.I'm thinking to give them a bit more nutes this week. They drink 5litre all together every day. pH 5,8.
I shower them twice every week with luke warm water, pH 6,5, no Nutes.
Here's a couple of the lady's showin of their goods...

whats up dokkie ? looking good man lets get some co2 and c some grams per watt, maybe a perfect room next time ? make me a believer

http://shop.sunshine-systems.com/product.sc?productId=9 best leds eva they are 500 off at a new price of $1299 ouchhhh but they seem to work real nice.

The 300Watt Spectra units I use Have UV and IR leds, These are USA made LED's, the UV and IR are specialy designed for these lights. There is alrewady lots of reassearch about UV and IR , so the bennefits of these two extra collor tempretures are clear.

so these colas are 400watt hps equivalent?

Here's some of that research about UV and UV B. Here's a list of info consurning the spectra and what the different colors trigger in the plants. The source is in Dutch, but I translated it..
-----------------------------------------------------------
Radiation: -----Newton metre: -----Effect on plants:
UV C----------- 0-280 < 300-------- Doesn't reach earth
UV B----------- 280-320 300-320--- Triggers Photomorfogenesis
UV A----------- 320-400------------- Triggers Photomorfogenesis
PAR Bleu ----- 400-500------------- Triggers photomorfogenesis and photosynthesis
PAR Green---- 500-600------------- Is reflected
PAR Red------- 600-700------------- Triggers Photomorfogenesis, photosynthesis, chlorofylsynthesis and photoperiod.
NIR far red---- 700-800------------- Triggers Photomorfogenesis and photoperiod
NIR closeby IR 700-3.000----------- Primarely heat
FIR far IR 3.000-100.000------------ Heat radiation
source: http://www.groeiservice.nl/downloads/Kleuren%20de%20invloed%20van%20golflengtes%20op%20het%20gewas.pdf
----------------------------------------------------------
Now we can see that the UV-A in de Spectra Units triggers photomorfogenesis in the plants just like UV-B.
Only UV-A is harmles, compared to UV B which gives you cancer.
The proces photomorfogenesis leads to the final shape,colour and growth of the plant. This is mainly determined by genetics, but is triggered by light.
So without the UV the buds won't develop in their final stage.
And its almost common knowledge, that UV triggers the production of THC .

you almost have me sold on these LOL
