First grow. pics

Hey this is my first attempt at growing about a month in. I have 4 very nice looking plants and I was just wondering if anyone knew how long it would be until they will reveal there sex. So far I see no pollen sacs or pistils forming. I have these plants in a 3x3x4 Box under 2 150 watt equivilant cfls. I think the actualy wattage is like 45 on each or something close to that. I havent had any problems except for the bottoms leaves on the one plant look discolored. Any suggestions or ideas for making this grow more succesful would be greatly apreciated

first off your pictures suck but ur children will show their sex prob in few inches or feet depending on the strain, but it'll only actually start flowering once ur in 12/12, and as far as suggestions, top them all and get a small hps for ur flower, (itll make u cream yourself compared to the cfls u got running now, good luck brotha

Well im low on cash. like I have no money. none. the point of this is to get some money to redo my basement.. move down there get a hydro system with an hps and grow on a larger scale. I just have to work my way up there
