Metal Halide Lights and Hardening Off
Tomato Folk,
Right now I am using at 430 watt High Pressure Sodium light. These are Yellow Red light in the spectrum. They are good for seed starting. Every year when I take my tomato plants outdoors the leaves burn at least a little if not a lot. If I was to use the 1000 Watt Metal Halide (blue) light instead that my brother just loaned me would I avoid leaf burn when I took the plants outside? Greg |
