I will have to ask my husband what lights he used. Yes! It is the 2"x2" blocker from Johnny's seeds. I absolutely love it!
Edit: He said the lights were Sunco brand.
We converted garage storage shelves into seed starting shelves. We bought ours from Menards for around $150 and rigged up some grow lights which I believe my husband said cost around $75 for the grow lights including the bulbs. So instead of paying $600+ on smaller seedling shelves we spent $225...
