High output flourescents are great for seedling growing and seed germination in that they don't put out a lot of heat and can cover pretty much all important spectrum illumination. Here's what we use in our greenhouse. It's a Metal Halide/ Sodium light fixture with 800watts of output. There are two in our greenhouse. The one pictured here is over the propagation bench and the other is over certain orchids that require significant daylength alteration from our own here in Southern California. |
