You might say I am doing this sog style but my intention is to veg untill 2/3 of growspace is full then induce flowering, also I read somewhere where you can sex a plant during week 2 of veg switch to 18/6 for 2 to 3 days then carfully inspect each plant for sex and eliminate the males then go back to 24/7 the rest of the veg stage. Is this true and do you recomend this.

my ultimate goal here is to get max out of each plant and space, time is not a factor.
You are actually right. The plant uses CO2 for both stages, veg and flowering. But they use alot more in the flowering phase when they start exploding with buds. Typically the ambient air flowing around your house has 200 -300ppm of co2. Which is plenty of vegetating plants. But if you grow in a cabinet or a smaller space.. that level would be much lower.

As for growing space... I don't think it would be a good idea to use 2/3 of you growing space. Plants stretch alot during the first 3 weeks of flowering. Some times (especially for SOG plants) they stretch three or even four times their height depending on their genetics. So I would suggest if you have 4 feet to work with... flower them when they are about 8" tall and you will have plenty of room. It sucks when you flower them and they are too big and the grow all the way up to the lights and get burned. As for sexing the plants ... don't worry about it... They will show sex when they are ready. They usually show sex for me right as i put them into flowering. If you do anything... I would just give it a mild dose of some bloom nitrients. The Extra P-K will help the little pre-flowers grow alittle bit so you can recognize it.

B.T.W Good job explaining the Sugar-water method. You know... After you have used up all the sugar in your jugs... All thats left is pure alcohol and water... All you have to do is distill it...:thumbsup:
