Don't think that the more you do will give you more in the end,it all realy depends on the size of the room that you are growing in.In a room of around 4ft/4ft square with a little bit of height say 6/7ft go for around 4 plant's.If i was you then i would go for a soil wilma sytem set up or hand watered this will allow you to move the tubs around for max light on the plant's.Use advanced veg and bloom and you should pull at least 5/7 oz per plant if flowered at 1 1/2ft tall use the bloom with bud blood for 1st 2 week of flowering then at start of week 3 big bud and bloom then at week 6 bloom with overdrive and sit back and smoke a fatty.It is ph perfect also all the ppms are sorted depending on the ammount of feed you add so this will make things so easy for the novice or a long term grower who has not used it before good luck any questions inbox me.tyke..
