So first shoutouts:
To Pinstripe- for showing me that LED PC grows can yield decent amounts
To Blynx- for general badassery in growing, and for showing me that white LEDs can get 1 gram per Watt. (I also have a few off the shelf LEDs bulbs that I intend on using at some point for another mini project)
To Dion- for the general concept of the "el Cheapo." Seriously CAN WE MAKE THAT THREAD A STICKY? Because it's full of awesome.
To Killkingkong- I kinda ripped off your idea for magnets to attach the lights.
Lastly Mr. Sparkle. For inspiring me to post my own setup.
ON TO THE GROW:
This is my second grow, the one I had before was under lit, over heated and produced a male... So this will be the first one that produces anything.
Any potential problems/areas for advice, I have put in red.
Aims:
Short term simply to build a box that is capable of growing weed, quietly discretely and without smell. I'm trying to get something that can go just one cycle without it getting too hot in there or stinking up the place I live in.
I believe the lights can get me 1Oz+ in future grows, from what I see here. That's my long term goal with LST/Scrog and hempy bucket technology.
Setup:
Case:
An old PC Case that's approx 0.85sqft (17x7") by about 2' tall. So far I've just sealed all the massive holes with duct tape, I'd like to, at some point, use the back of an old power supply to cover the power supply hole and maybe use some MDF to cover the other assorted holes.
I've covered one wall with some diamond foil I had lying around, three other walls are covered with aluminum tape. I still have to do the back wall, I will sometime before flower.
At the moment I'm struggling with lightproofing. My intakes are some speaker holes at the front of the case that I'm going to make a scrub ninja cover for.
Lights:
This is the juicy bit. I made a modified el Cheapo from Dion's post (seriously... sticky)... Instead of having two strings of 12 on two drivers I got a 2A constant driver and made four units of COBs.
Each unit is one heat sink with 6 CoBs wired in series. The units are then wired in paralel. If my calculations are correct that's 500mA a piece and 18-24V to drive. It's working, in any case.
They're attached to the roof of the cab with L-brackets, which have first been attached to the heat sinks with superglue. The brackets are then attached to the roof with strong magnets. The glue holds for the most part but has come loose twice on two isolated brackets, meaning I've had to re-glue. I'm thinking that soldering the brackets on might be a better idea. But the glue is rated to at least 120celsius. Thoughts?
Ventilation:
80mm PC fan. I don't have the stats on it because it's about 10 years old and I dug it out, but it seems quite powerful. I have another 80mm PC fan that's not very powerful at all providing air circulation. The two are wired in paralel from a 12V power supply. I used screws that were slightly too long as I want to make a cardboard carbon filter that slots over the fan at a later point.
The Plants
Tub 1:
Nirvana's Aurora indica. Feminized. I started to LST Her but I'm finding that it's so bushy that I can't really LST without string rubbing on a growth point (the internode distance is THAT short, I can't find a bit of stem without a node!). As a result I've stopped trying and just topped her. She'll maybe get a little LST of the growth that results, maybe just more topping. I'm growing in Hempy buckets as it's simple and easy.
Tub 2:
Some nirvana mystery seeds that I sprouted, intending for a mini SOG. I germed five initially and put them into soil. The soil seems to have been pretty fucking toxic to them, however, and they didn't look so healthy (in fact two died). SO I took them out, washed their roots and stuck them in a shared hempy. The little one I just transplanted yesterday, the other two about a week ago. They've perked up a LOT since I did this. I'm not sure how they'll do in the same tub, but I don't mind this round.
So that's it. That's my setup. Waiting for your questions/comments/advice.
