I have just been given a 400W cool tube 400W HPS (Phillips Son-T Agro) and im considering not even using it...
The light output from the HPS is nowhere near as bright as the LED panel i built a few months ago and its only running on 54 of the 78 3W LED's (that's 192W).
Am i missing something here or have other people noticed this too?
The four plants i have under the LED are 6 days above ground and are already producing their 3rd set of leaves.
