4EVR420,
Great job and great idea. That would make a perfect cloning/seed sprouting cabinet for a larger operation!
Did I understand that your 2 intake and1 exhaust fan are all in a row near the bottom on the back? If so, for your next project you might consider that they are much more effective if you put intake near the bottom and exhaust near the top, because presumably the exhaust will be removing heated air and the hottest part of your box should be near the top.
Also, usually the intake and exhaust equal each other and 2 exhaust fans pulling out with 1 intake fan pushing in would be a more efficient sue of 3 fans than the way you have it set up.
I've never understood the reasoning for the fans included in the UFO setups since their big claim to fame is there is virtually NO heat. If that is the case why do they need so much airflow?
I guess depending upon how it is directed it could double as the air flow fans, but that seems a very unlikely fringe benefit.
Anyway, getting back to your setup, it is working great for your purposes and that is all that counts. For something larger, you might look at a larger fridge since you already have this down. That way all you would have to do it just increase the scale or even better if you can find one would be an old style upright freezer because they are basically a box with shelves rather than crispers and those other things you find in fridges, plus it is all in one big box rather than several smaller boxes. Equally important is they are light tight and well insulated so the surrounding environment doesn't have as much effect on the internal environment and it also helps to keep thing quiet.
Congratulations and welcome. I haven't seen your posts before,but from the looks of it I will be seeing more of them in the future.
What variety are you growing and are they autoflowering or regular?
That might explain the very closely spaced nodes. Incidentally, my horticulturist at the grow shop, says that in cloning if you have nodes that are spaced real close together, then you just get more root sites and not to worry if you last site is near the surface of the growing medium. Speaking of medium, you might check out my post on Alternative to rockwool. The STG medium sure looks like a good alternative to both rockwool and hydroton.
Good smoking.
