Strains for hieght restrictions?????

What's up every body? I've been growing for alittle while now and think I'm ready to spend some money on seeds. I've been using bag seeds and info found almost entirerly from this sight and you guys all pretty much know your shit, thanx.
Since I've been using bag seeds I've been experimenting with topping and training due to the fact that I only have about 4 and a half feet of head room in my grow space. My question is if any buddy can tell me of a strain that grows short and is suited well for indoor growing or of a stain that takes good to being trained. My space is about 5'x5' with one 400watt M.H. for vegging and 5'x10' with two 250watt H.P.S. and one 400watt H.P.S. for flowering.
Thanx, Redeyed

P.S.
I grow organic and use kelp for stress if that helps any.

you can purchase skunk special from female seeds(femaleseeds.nl), they sell 4 seeds packs and this strain is a bushy plant purposed to SOG without topping it. All the branches will make buds, and on my last grow they were 1 foot and a half at maximum. They yielded 290 grams for 4 plants with a 600 W HPS SON AGRO, the high is very good, more indica than sativa, but for bushy plants it's normal.

fhydro,

How much floor space did the 4 plants take up?

They were only 18" tall from the growing medium?

Have you used that seedbank before? Good/OK/not-so-good?

thanks,
