Oberon46,
Are the tubes plant lights or just regular shop lights? Low lights combined with high temp will make for spindley plants. They are actually stretching for light. Yes, sun loving plants require 16 hours of daylight.

I have 156 Daylily seedlings growing in my plants stand, including 2 shelves of 4 foot long shoplight with growlux plant bulbs. The lights are on for 16 hours. I use a timer.

Edited to add that I use tinfoil to reflect light.

Photos taken March 2012. They will be planted out end of May
