Mung Bean Sprouts

mung beans in pitcher set-up

I love mung bean sprouts but I may have gotten overly zealous when I decided to soak 2 cups of mung bean sprouts at one time...  The 2 cups of dried mung bean seeds turned into 6 cups after soaking!!!  I've had to split them up into two pitchers!  Mung bean sprouts are hydroponic and, like sunflower seeds, require weighting.  So currently I have the mung bean sprouts in one pitcher with a second pitcher inside the second pitcher on top of the seeds.  Inside that pitcher is a 1 quart mason jar filled with water.
My very supportive significant other (did I mention he was awesome...?) is currently, this very minute, in the process of drilling small holes into the bottom of two more of these identical BPA free plastic pitchers, which I found at Wal-Mart.  Once those pitchers have holes in bottoms (for draining), I'll transfer the mung bean sprouts into the draining pitchers and the setup will go as follows:
1. Solid pitcher.
2. Inside solid pitcher will be draining pitcher with mung bean sprouts.
3. Inside draining pitcher and on top of seeds will be another solid pitcher.
4. Inside the solid pitcher may either be water (for weighting) or, to reduce potential for spillage, I've put water into a 1 quart mason jar and then put the mason jar inside the top solid pitcher.

I'm choosing the three-pitcher method with mason jar of water because having the middle draining pitcher allows excess water to drain and better air-flow, which is important for sprouts, and the top solid pitcher allows better distribution of weight over the mung bean sprouts. 

I'm going to keep looking for more of these soft BPA-free plastic pitchers because I'd like to use the draining and solid pitcher set-up for soaking and 1.5-day rinsing of the sunflower, pea shoots, and wheatgrass seeds.  Using all the various draining devices and pots in my kitchen was a little crazy!
