Yes you can. Ive seen it at Wal-mart and Home depot...I dont know about Lowes though.
I know, but be happy you're getting good info now instead of after your grow when you can't do anything about it. ;-)thats the worste news ever ... i will try for some more lights. as long as the lumen output s like 12000 or more for my space i am good right?
Just as a note for your future grows. Roots grow best in complete darkness, so use a cup that is completely opaque. I use Solo cups, but any opaque cup is ok. This may be the reason for abnormal growth on the seedling in the clearish cup.the deformed at about 2 weeks..
