This is confusing, your 4410 grams should be the maximum amount you can carry in public places on your person. It should equate to a 30 day supply of your prescription, so if you went on vacation you can take your meds with you. For some reason yours should be 600g not 4410.
You can store in your property any amount of weed you like.
What you have to be careful about is having a large plant count with multiple lights creating a very large power bill and being on a disability pension, or an income that shows you can’t afford that power bill, unless you are selling weed or something else to create a secondary cash income, and not declaring it to the Taxman.
