Well... It's been quite awhile since I last visited this site. just thought I would post up what I've been working on recently.
This is my 250w mixed spectrum computer case growbox. I say mixed spectrum because I'm using a 150w HPS and a 100w CMH bulb.
For those of you who don't know about Ceramic Metal Halides (CMH) I strongly suggest you look into them. They put out a much more balanced light spectrum (including UV-B) and run cooler than an HPS. They really are great bulbs and so far have blown the HPS out of the water. Vegetative growth explodes under these bulbs. The nodes are nice and tight and the plant throws tons of branches. Perfect bulb for veg or flower.
Anyway...
I basically took 2 identical computer cases, gutted them, and then bolted them together. Each computer case measures 22"H x 22"L x 8"W. Together that's 22 x 22 x 16. I bought pyrex baking tubes and used those as cooltubes. Each cooltube is hooked up to a 80mm fan at the back of the case which exhausts the hot air from the bulbs. Also conected to this system is the ballast box which I set up inline to be passively ventilated from the front of the case. So pretty much... Air comes in through the front of the case, through a piece of pvc pipe, through the ballast box, through the cooltube, and out the back of the box.
Then I have 2 120CFM computer fans that exhaust the actual grow environment. Each of these computer fans has a homemade micro carbon scrubber connected to it that also serves as a muffler. All 4 exhaust fans are connected to a 4 fan speed controller. The speed controller also has 2 heat sensors I can position within the case to read my temperature.
I am setting up this grow box to use 3 DWC (deep water culture) bins. I will have 2 plants per bin growing hydroponically. Above them is my SCROG screen that will help me increase my yields and control the plant height.
Also hooked up to the case is my CO2 maker. It's made by nutrafin (fish company) and uses a simple chemical reaction to create a constant supply of co2 for about 3-4 weeks. Eventually I might get a small 2.5lb tank and a regulator to have a more professional co2 delivery system, but for now this works just fine.
as far as the 6 strains I'll be growing...
I'm thinking something along the lines of:
Bubba Kush S1
Legends Ultimate Indica
Trainwreck x Purple Urkle
Banana OG Kush x Sour Larry OG Kush
Chemdog Double D
Hashberry
edit: here's a few pics.
The third picture... I'm trying decide which SCROG screen to go with. The 1" grid or the 3" grid. I know the 3" will probably give me bigger colas and be easier to work with. But I'm wondering if I'll get a bigger yield using the smaller 1" grid... Anyone have any thoughts?
and the green thing is the micro carbon scrubber made from a pencil holder, wire mesh, some clamps, activated carbon, and pantyhose. In total it cost me about $20 to make both of them.
