if you are growing from seed, forget about the screen(pulling a male out that has become intertwined with the mesh and females could be aggravating)

to keep them low, just lst them every couple of days, you'll end up with a "hanging basket" looking plant with many many branches.

as for a strain 50 50, i do not know; i am growing blueberry and would recomend this strain to anyone (most excellent bud) but is a 80 20, with a super strong couch lock effect.

every one should try a bagseed grow, it is a perfect opportunity to experiment, and if you bungle it, you havent lost an exhorbant amount of money in exotic seeds.

for low growing, pick an indica dominant strain.(like blueberry!)
