This product definitely grows like a weed!  A weed that our birds absolutely love to eat!  
   A friend bought some seed from one of the organic seed companies in our area and did a experimental crop.  She planted whole, soaked, sprouted, spray millet in rows like you'd plant corn.  The plants were HUGE!  
   This last spring, we tried some different varities... - white proso, milo, japanese and german millet seeds.  We also were able to get our hands on some broom corn seed (this item is really used to make brooms).  Again - planted in rows like corn.  The broom corn was 8 feet tall!  The millets ranged in height from 3 to 5 feet.  All had wonderful spray millets attached!  
   One thing is for certain - the FRESH stuff.......right out of the garden is definitely preferred by the birds.  I picked some of the plants green and the birds relished them.  The broom corn was very interesting - the straw-like strands have seed pods attached......like mega millets.  While the birds didn't seem to have much interest in eating this stuff - they definitely enjoyed ripping it up!  My parrotlet uses his "broom" (attached to the top roof of his cage) to hide in.  Kinda like a fort!  Finches and canaries have a ball playing in it!  They also used this item for building their nests in the avairy.  
   We've shared these products with local bird enthusiest in our area and received a lot of positive feedback .......both as a treat source and a natural toy!
  I'll try to get some photos of the leftover harvest next time I visit.  I did find a website of a farm located in Canada that has a few photos of spray millet growing.
