Question: Does the temperature of the germination medium have any effect on the lettuce seed germination? ||  ||   || germinated with a heated pad under the medium. We observed that the heated tray seedlings were leggier and thinner (shown right) as compared to the room temperature sprouts shown below. || ||   ||   || Blue and Red LED Grow lights for half of the system and a flourescent "Gro-light" for the other half. ||  ||   || Water is pumped up to the hydroponics system from a 40 gallon fish tank with goldfish located below. This provides a nutrient film of water to the roots of the lettuce growing in the troughs. || ||   ||   || || A small Raft-style hydroponics system (below) is set up by the windowsill next to the typical soil growing medium seedlings.
