no there not in the water the tub and watering system was cleaned with bleach and then rinsed with bottled water and that is also the water i was using with the super thrive added in. and they were under two two foot 20w shop florescent tubes... but i am using two 40wat 4 foot ones to grow all my little plants and that works fine and i have used those two 20w ones to grow plants before too though
