Depends on state laws, federally they are not enforced in most local state jurisdictions, in my state its been decriminalized, and in 2014 its on ballot for legalization for recreational use over 21 years of age for up to 3-5 plants, or 2.5 oz personal use cultivated. Here if you got caught with those plants you would face a fine, not a felony... I guess you live in state that has not decriminalized or legalized?
"Decriminalization
The state has decriminalized marijuana to some degree. Typically, decriminalization means no prison time or criminal record for first-time possession of a small amount for personal consumption. The conduct is treated like a minor traffic violation"
1lb - 20lbs can be a felony and 5-10,000 fine where I live, but its going to be the same if you flower 1lb after legalization anyway, as it exceeds maximum amount, I don't know how much those plants would account for in weight though tbh.
I suppose if your growing more then personal use, it would be treated a bitt different then a decriminalized possession.
