Thanks GPS!
The kind of bugs I am worried about are the thrips (little bugs that you can barely see). What makes spinach kosher is whether or not there are bugs present on the spinach that can be seen with the unaided eye. So, for example, those little thrips and bugs that size, they are hard to see but can be seen but you have to look real close for them. But, just like you said, if you get roaches and moths in your house, I bet I can get thrips too. But there is a reduced likelihood. Thanks for reply. I found your information very useful.
I am going to look at getting more
fluorescent fixtures and
bulbs for now as with the
lights I have now, it will not be enough.
