vegetative growth vs yield

[duguP]

My question has to do with the vegetative growth vs yield.

I am using the 12 site ebb & gro system (pictured), and the planters are 2 gallons each.

Can anyone tell me, or point me in the direction, of how to find an optimum time to begin flowering? I dont want this to be a 7 month grow, but I don't want to run a quick 8 week sog either.

I know it all depends on the specific strain to find out exact numbers, but logically I think percents would be okay.

For example: If I start to flower at 12 weeks with a certain strain, it would produce xx % more yield than if I would have flowered at 8 weeks.

Twelve weeks of veg will give you HUGE plants.
Something like M blaze's 8ft. Jack Herer.

It depends on each setup/system’s capability combined with a few general parameters.
　
For one many growers do not figure their actual usable height when they start making decisions that those things should at times be factored in.
　
Start with your maximum height and then subtract the height of the top of whatever growing medium is being used. Then subtract the distance from the maximum point your lighting can be raised to the bottom of your lighting. Then subtract the minimum amount of distance you to maintain between your lighting and the tops of your plants.
　
That gives you your maximum usable height.
　
Then you look at your lighting/reflective material combination and see if it is capable of delivering adequate lighting for that entire amount of height so you do not end up with tall plants with little to no production on the bottom third or quarter.
　
If your lighting and reflective material is up to the task your maximum usable height remains the same.

If not it is cut to whatever maximum height your lighting system can be raised to and along with the reflective material deliver enough adequate lighting to the lower portion of your plants for acceptable production.

Now with hopefully knowing a half close idea of what actual usable height you have you then use the standard plants will double to triple in height during flower rule (most are more like double than triple) and do the math and that will tell you at what height you should put your plants into flower to get the most out of your system/setup.
　
For every day or week or maybe month that you spend vegging that will result in plants outgrowing your lighting has been wasted and would have been better off spent on harvesting your crop and drying it and putting it into cure while the beans you popped right away are already through the surface and beginning to veg.
　
Each day or week or month of wasted veging time adds another day or week or month to the overall length of time from the day you plant your popped beans until you take your first fully cured toke and you will receive nothing to almost nothing in return for it in production and you will have also spent more in electricity and likely in nutrients used too and you may have then handled the plants more in that amount of time so that adds some small risk of damage, then there is just the old longer number of days, more times to raise lights and to water and to feed etc. and if you get sidetracked or go half brain dead and make some error, even a minor one, it can cause a real problem so with fewer days there are fewer chances for those things to happen.
　
If someone has a setup that can grow sequoia trees that produce right down to the bottom I say do it each and every time but if someone’s setup has some limitations spot them, accept them and grow to them unless you can and will upgrade away a limitation.
　
In short … this is one case where bigger is not always better even if it can be had.

wow, thanks brick

Excellent post man! Thanks for taking the time to write all that our. You just saved me a lot of headache later
