Nah jonesy have you ever grown hydro? if he did go with 6 he would have to flower from clones or veg for short time.. cause if he were to veg a full month from lets say CLONES. Thoes plants would fall over/ be SOOO intermingled/ Topheavy/ A TIE NIGHTMARE/ and thats without topping.. these are my 4 in a 18gal res.
