The number all depends on how long you veg... You could do 16 in a SOG and veg for say a week or 1 huge tree that you veg for 3 months... It all depends on you..
hey jibba, rule of thumb is 50w/sq ft. so roughly just under 3ft x 3ft. you can definately do what you are after. also when introducing light to plants start of with nice distance maybe 30", but w/o a cool tube you will be looking to gradually working it down to 16"-20" above canopy. your buds might come out little less dense than if it were grown in 9 sq ft.
