Week 2 day 5
Trucking along, nice and bushy.
Two more days until the end of the week! Then it's time to flower and train a bit more!
Quick and dirty 5-day animation of week 2, still got 2 days to go.
So week 2 has finished and it is now time to move to 12/12.
Here's the final updated animation for the full week - looking nice and bushy!
cool .gif :thumbsup:
looks like theyll be some fat plants
Tied her down last night, changed the cycle, and here we go with the first picture of the week!
Week 3 day 2
Week 3 day 4! So fat I'm starting to worry, and they're not even through the first week of 12/12 yet! I might actually have to remove one of these plants and just let one take up the entire case!
well not the worst problem to have i was studying the picture to try and suggest some LST or something but there really isnt much unfilled space i wonder if there is a easy way you could recess the light or the pots to make a little extra room and widen the light pattern? either way nice grow so far. the slide show you are doing is nice.:thumbsup:
I've looked, I've drawn up ideas, I've done AutoCAD renderings, I can't find a single way to really do much better other than simply bending and supercropping these things as their training, and rotating them to keep them somewhat in line.Quote:

oooo... Computer Animated Dank
Week 3 day 6!
So much foliage. I think it is almost time I started trimming the fan leaf tips a bit to allow for a tiny bit more penetration.
End of week 3. First week of 12/12 finished!
Have an animation.
It's so hard to keep things in check with a grow so small. You think it will make it through stretch without exploding the CPU?
Watching this grow is making me want to start a micro grow. Actually I think I will this summer!
Your grow is coming nice!!!
If I continue my two week long supercropping/training it should be able to hold, JUST BARELY. The way it's looking I might have to literally cut a hole in my case and just set the LED panel on top shining through the hole for the headroom.Quote:

Update for 4/20, of course!
I'm still worried, they're getting larger and STILL DENSER every night. I've got some horizontal room left to go but the vertical space is suddenly at a MASSIVE premium. I am SERIOUSLY considering the original idea to buy a metal-cutting bit and actually set the panel on top of the PC case to have the extra vertical height needed to finish, because that's how hardcore the growth is compared to a PC grow with CFL, and I'm training it hardcore with every single node being pinched and bent if possible. Bear in mind this is an older A/V workstation case, it is larger than a typical ATX case.
Pistils are showing!
Yea, I know I was lax on an update - was out of town for the weekend.
Came back, thinned out the PC case some. There was some dead stuff that had been choked out by the thickness of the plant, and I cut away the bottom branches that were going to be far too small to produce anything worthwhile.
looking good:thumbsup:
i was looking at the pic and it struck me that if u took some opaque material (cardboard or something) and covered it in reflective material then used it to make a floor across the whole box just above planter u might be able to increase the light efficiency a bit. good idea? :stoned:
Not really, as there's rarely any chlorophyll on the undersides of the leaf. Best lighting is top and sides.Quote:

What if you get a smaller res. It looks like that ma get you another 1 to 2 inches.
Sadly this is the smallest thing I could find for a reservoir. I could maybe get another inch but the net pots themselves would be almost touching the bottom of the reservoir.Quote:

So my panels are so powerful I'm getting light bleaching on the leaves closest to the light.
Otherwise, buds popping everywhere! Sorry I'm not doing the animations any longer, it's just too much hassle and I've been so busy with designing new things (working on super-charged induction lighting now) that I just haven't had the time to do it.
ouch....i think you may be out growing and and over lighting that box!! :cool:
cool, hope they stop stretching soon :thumbsup:
This is exactly what I'm afraid of. looks like 50w pure power in just barely over one square foot of space is just too much. I might suffer on yield because of the sudden lack of room.Quote:

Anyways, I've been getting wonderful budsite production. They are a bit too numerous to count, but each one at the top is about the size of my index fingertip, and fairly dense-looking even though it is small.
We're just a couple of days into week 4 of 12/12. It's about time for that boost in production.
Buds are comin in nice man.
Just an idea for some xtra height, i used the little plastic cups for jello shots as net pots. Cut holes and used half a peat pot, or perlite as a medium.
Hmm, if I can get a reservoir that shallow then I might try that. Though I think my next run in the case is going to be in a taller and wider case for the best use of the light.
So I learned something today, and I should have thought about it well in advance.
Any light your plants do not use is reflected. Any light that is reflected eventually dissipates in the for of heat, thermodynamics comes into play.
Why do I say this?
Well, even with a second fan really pulling air through the PC case and plant thinning, I'm starting to hit temps of near-90. That poses a problem.
I'm definitely going to need to make a larger case for the next 50w grow. This is too small of a case for this much power and even though I've got nice frosty buds starting to show up, there are not enough for my liking. I really screwed up thinking this would pack the power in, I totally neglected to think of this like a basic solar-energy system - solar panels heat up from reflected light that they cannot absorb, leaves should act the same way. Even with airflow, the plant itself is getting hot, which is why I've got the burning even from a couple inches from the panel. Oh well, I've learned my lesson this time and next time I'll definitely keep this in mind.
Sorry again for lack updates. I've been doing tons of other stuff and by the time I'm done I'm too pooped to get online.
Anyways, top and side shots for you! This is week 6 day 6, almost 4 full weeks of 12/12 completed.
Still worried about burning though I was able to drop the plants down a bit and I haven't seen new burning appear. I know I'm going to not yield much because of all the problems that started, but I'll get some nice nugs without a doubt!
Just too much light burning happening. I also removed the 120w panel from over the two bigger buckets down below, and put in the 50w panel that was in the PC case. The plants that were in the case are now with the Krusty and DWC buckets under 100w total of LED. The case needs a serious redesign to see the yield I'm expecting from LED, there is just not enough airflow, and there needed to be better sealing on top of that.
I will continue to chronicle here, but no longer is this truly a 50w grow. In fact, though I have two 50w panels, they're spread out more to hang over the larger plants, so at best I could maybe consider this a 30w LED grow.
But seriously, 50w LED was way too much for 1.25 square foot of space. I won't make that mistake again.
Do you think it was to much light since it was in such a closed in area? Not enough air flow. Or it is just to much light. I use over 100 watts of HPS per square foot and I did not get any burning. Maybe a little, but only towards the end of the grow.
I don't know. I have never used LED's.
Your two grows are looking good.
When it comes to light and plants, things act a bit differently. Plants have some unusual properties that makes light interact in different ways, not unlike how some metamaterials act. I had good airflow, however I don't think it was the issue though more was likely needed. The problem I had was I was simply pushing too much power in such a tiny case. As light hits a plant, most of it is never absorbed, it's either reflected off or radiates back off the plant as heat. What I'm betting on was the plant itself was getting too hot from the bombardment of pure usable power it couldn't absorb and thus it turned itself into a krispy kritter.Quote:

could you possibly poast the build specs on your hydroponic PC xD... Im new to growing and this seems like a really stealthy grow build.

Sure, but I'll tell you right now that in the box, 50w of LED was TOO MUCH.Quote:

No carbon filtration was used in this box. The 50w panel is my own company's panel.
I'd really recommend a box with about double the width and another 8 inches of vertical height. The footprint of my case was just over 1.25 square feet, with usable space equaling about 1.5 cubic feet, and 50w LED was just too much light. It was fine and dandy at first, but after 3-4 weeks the burn started up when the plants got about 2 inches from the light.
I am consolidating the rest of this grow with the Krusty Bucket journal kept here: http://boards.cannabis.com/hydroponi...-led-grow.html
This grow got too out of control. Too small of a space, too much light.
too bad the PC case SWC didn't work out, but that's tough to pull off in an area that small...
I have a regular PC case that I'm planning on using, at this point its trail and error and I do not plan on using any high quality strains on my first shot.Quote:

3.I have two fans built in for plenty of ventilation
4.I need to find some nutrients from walmart or something that will work
5.Im using gravel for my growing medium.. I never really got much direction in that one, its hard to find good suggestions
Let me know if I'm doing this at least half right, Im not going to even germinate the seeds until I know the environment is the best it can be.
Perhaps if the grow box is not large enough I can transplant the plant to a outdoor grow location.
Get rid of the 100w incandescent, or you're going to have MAJOR heat issues regardless.Quote:

Good job with two fans, especially if they're 80mm. I used a single 120mm.
For hydro, if you have no hydro shop, Florikan Dynamite from Walmart of Home Depot or Lowes will do the trick. Grind it up into dust and use about a teaspoon per gallon to start off.
Gravel works, just as long as your chosen medium can remain as pH inert as possible and allow for the roots to get a stable grip on the medium and hold itself upright. Make sure your net pot has enough holes to allow for roots to come out and flow into the tank.
And yes, air pump in the nutrient reservoir. Oxygen is very important for root and plant health, and dissolved oxygen levels in the reservoir must be kept up or else you'll drown the plant or invite a pythium infection to come by and wipe out your plant.
