I finally decided a growing light system would make my gardening life easier so I shopped for the best I could find and ended up with PL Lights from the Netherlands,reviewed as the best system for my needs with Sun IX System as the second choice.
It's the HPS version and I ordered it with the standard HPS bulb even though the PL light company also manufactures the Hortilux(sp) light bulb which I found out after I ordered :( I may have been able to save a few $$ ordering that bulb with the system..who knows.
Ok,my question is,will the standard HPS bulb have enough of the proper light spectrum to suffice through the whole growing process(orchids and tomatoes etc:)until I upgrade? In any case for future reference,what are the reliable online discount houses to purchase HPS type Bulbs?
