urban garden center hps bulbs $43!!! regular price.

i do not buy expensive special spectrum anything. i figure, until i can get everything else perfect, whats a few lumens of light. look at all the light lost behind hoods!!! that is why i dome the ceiling and free hang my lights. better, more productive way to spend my money!

.....and i'm an electrical engineer!

I buy the cheap bulbs too - I did a side by side with a cheap bulb in one hood and one of those $150 bulbs in the other (with panda wrap in between!)

and while the results were impressive to the eye, the math did not pencil out.... over the life of the bulb, the price didn't make sense.

Generic black digital ballast, "grow Lite" hps bulb:

65% increase in cost to the lumatek, 5% increase in yield.
