Yummm! That was my next question but you just answered it! Looks great! Ive never had watercress but sure looks good! I love collards, spinach, kale, turnip, mustard and most other greens and that seems like something i need to try! Them Hasiyas are crazy good value for harvesting anything. They are heavy duty and you just cant find anything else in it class to do the harvesting job it does!
