bigs asked me to chime in here

LED's are awesome...they provide exactly the wavelength for your plants to make photosynthesis..building larger rootmass and healthier plants. My lights have 3w diodes that are stronger than the typical 1w models allowing more penetration and yields comparable to HPS. They use less electricity acheiving the same results..except i hasve found my meds to be more potent since switching to LED's...bummer for me:smokin:...they give off minimal heat therefore eliminating ducting heat out. I have been growing in a soil/coco medium but i think LED and hydro/aeroponic applications would do well together. :thumbsup:
