Simpler bucket drain system?
I've reviewed lots of home-made BSF bucket growing system and I think I've come up with a simpler and cheaper solution to the drainage issue:
I bought a Lowe's 5 gallon bucket and drilled a 1-inch diameter hole in the middle of the bottom. Then I duct taped a piece of square (3x3 inches) window screen over it (leaving the center open of course) and finally I poured 2 inches of pea gravel into the bottom of the bucket.
The bucket sits on bricks to make sure the drain hole is exposed to the air so it doesn't get clogged with soil. I drop my food waste directly onto the gravel, so there is nothing separating the food waste from the pea gravel. My theory is that the BSF larvae won't churn the gravel much, and if they do it will re-settle to the bottom naturally since it is denser than anything else in the bucket.
The 2 inches of pea gravel should have enough void spaces to allow liquids to easily reach the drain hole. I am hoping that these void spaces will trap enough waste that the screen will never get clogged ... but if it does a quick blast with a garden hose should clear it with minimal effort.
Does anyone have any thoughts about this simple new drain system? I'm always looking for simpler and/or cheaper solutions so I hope this one works.
