Maybe sometimes go to the local hydro store, the owner will recommend you some good stuffs.since most the store front sell led light, nutrients, soil and some garden tools, I think the Jamaican or other better options can be found many places
,i like to talk with the store owner everytime and the man is helpful and polite, that easy for me to get friendship with them. sometimes i will recommend the store around me to sell some hot products, since i will use it further time, then they listened to me.
