Your question: What is the limit a basic patient can cultivate in solano county?
Here is what I found:
Based on the latest from, http://www.co.solano.ca.us/depts/ph/medicalmarijuana/faqs.asp
It looks to be that SB 420 allows eight (8) ounces of dried mature processed flowers of the female cannabis plant (buds) AND no more than six (6) mature or twelve (12) immature plants per qualified patient. Counties and cities are authorized to establish higher (but not lower) limits if they wish.
To be safe and sure, check with the Solano County Medical Marijuana Identification Card Program for the latest on your area’s regulations: http://www.co.solano.ca.us/depts/ph/default.asp
Be safe & healthy!
