Og kush#18 and tangerine dream outdoor sizes?

So i'v started 2 of each indoors so far vegd in 16oz cups for 2 weeks and now there in 2 gal pots for at least another 2-3 weeks then a further 2 weeks in their final 8gal buckets then they go outside for flower.

with an indoor veg time of around 8 weeks under cfl's in 8 gal pots (i know not ideal as they wont veg huge under cfls) what would my yield/size be, iv only ever done one plant in a 3 gal outside it yielded about 2 ounces but stayed short with heavy branching.(4 week cfl veg)

What i wanna know is how tall and big are these babies gonna get.

Is it reasonable to assume around 5 zips per plant? outdoors the sun will shine all 12 hours very strong with pretty much perfect temps and conditions.

Also is it reasonable to assume that an 8wk veg under cfls would equate to roughly the same size as a 4 week veg under say a 600w hps/mh?

this is all for personal use so really just looking to find out if the 4 plants will be enough to last me a while or if i should get popping some more seeds.

There are simply too many variables from one grow to another, one grower to another, one strain to another, to guess the yield, or veg time of a plant before it's grown.
It is reasonable to think you can pull 5oz per plant in 8 gallon pots with 8 weeks veg. I would even say if your skills are decent, you should be able to pull at least close to that #.
Good luck!

it could range from 1oz to 2p's

huge amount of variables and factors

where are you located?

is your outdoor light schedule at the point that they will flower when they get outside?
or will they continue to veg outside?
your post is a little unclear?

I started vegging plants in march this year then put them outside in the ground in late may. they vegged till mid august then flowered

i got a pound each per plant

but mine were in holes in the ground, not pots
