Haha, I was wondering about that too, and add to that the electricity cost. Next you need to buy is a good timer.
Led Princess sales staff were nice, but I still thought it was too expensive.
Anyway, you already got it. All the best in LED growing. Besides heat-tolerant tomatoes, I would choose a short compact one that wouldn't go tall, or the 120-watt LED will only be effective at the top part (unless you buy another one for the lower extremities).
Yes so far the start up cost is high but I think LED is much more energy efficient than our usual fluorescent tubes... but then again, have to see how that adds up to the bills in Singapore!!
I've actually thought about DIY the whole rack for the LED lights and plants but in the end I got a ready made shelving from NTUC at a good price! Will share some pictures later!!!
For the 120watt LED, I will be doing up on enclosure with white background (or mylar if I can find), the reflections should enable the light to reach the other parts of plants hopefully!
As for timer no worries, because I work from 9am - 6pm.... I can turn it on when I leave the house say 7-8am... when I come back, go about my usual business, I sleep around 11pm, so before I sleep, i'll turn it off!
Now I just hope, it doesn't catch fire and burn my room down!!!
