I would get the automatic sprouter.....EASY way to sprout a variety of seeds....andf to the good side you will not be growing wheatgrass like Jack in the bean Stalk....shorter 5-7 inches is better, younger and more vibrant, again just my opinion.....and hundreds of customers for the past 9 years.

Check out the Sproutman (Steve Meyerowitz...he has one that he recommends.

The COLDER dryer air by you is a benifit!
Try to use defused Natural SUNLIGHT.....Grow lights will get the wheatgrass to grow...BUT the natural CHI (energy ) will NOT be as potent. ps. Skip the salt in the water....and put the kelp into the grow mix.
If you try AZOMITE(mineral rock compound) be careful....it can make your wheatgrass taste terrible if you go much beyound just a little.....Kelp is BEST!(my opinion).

Here If I water too much....or plant the seeds too thick in the SOILESS custom grow mix Mold will be evident for sure.(COMPOSTEDsoil mix...according to to modern Organic Certifiers is more apt to induce Ecoli or Salmonella potential) Topical Mold has been tested to be harmless....but it is not pretty. Subterainial MOLD...can make you sick or kill you.( a while back they removed ALL the packaged spinach for a while.)

Big shin-dig for my 8 month old Grandaughter today...gotta go.
