How long to veg when SOG?

Is 25 days (counting from when seeds sprouted) ok?

I have 30 plants under 1 600w HPS, i'm guessing maybe around 12-15 will be females.

I'm also very curious, will the top/"main" bud be smaller on a plant that has only vegged for, lets say, 2 weeks compared to 1 month? Or is the only advantage of vegging for 1+ months more branching?

What yield can i except / plant if vegged for 25 days do you think? Flowering will be normal of course (~50-60 days or so depending on strain). Is 300g (10 oz) doable for 12 plants?

I know the last guy i read that finished with a 600 watt came out with 8.5 oz.

I am not sure about the vegging longer = bigger cola question, but my guess would be no, it doesnt matter.

I have also read a general rule of thumb is if you do it perfectly you should end up with 1g per 1 watt. But that is for pros.

300 grams sounds like a reasonable goal for a 600 watt set-up. That gram per watt is under ideal conditions, 1/2 gram per watt is easily obtainable.Good luck with it.

ok if your gonna do it like this i suggest you cut all the bottom branches for each plant so the only thing left is the top 4-7 internodes then use all the bottoms for your sog then it should be fine but veg for about 2-3 weeks for the clones and keep 1 or 2 mothers on a veg then you can always start a new sog. when keeping the top cola only it will produce big dense top cola's. right now i have some dynamite(next generation seeds) growing and the top cola itsself is about 50-70g on each and there only 19inches. but i have no bottom branches so. if your plant veg for 2weeks im thinking the outcome will be around 20-40g as to 1 month will be around 50-70g. but it really depends on strain.

The taller the plant more room it has to grow that top cola. I wouldn't let them get too big tho fitting that many under a 600w. Better to work with clones, veg to 6"-8" and flower them.

Thanks for the replies.

About cutting off the lower branches, doesnt that stress the plant quite a bit (+ it needs to heal?) isnt it better just to bind down branches that sticks out too much (more work but..)

I've fixed lights for clones and 1-2 mothers. I think i go for 25 days vegging as i intended.

Takes less energy to heal then it will to make them lower buds, but thats something I plan on trying myself and seeing the difference.
