Next Years Plot, take a look.

ok so my outdoor grow area is a dog cage 6ft wide and 9 ft long, plants cant get any taller than 5 1/2ft. right now i have two plants in there one in the ground and one i started late thats still in a pot. the one in the ground is almost exactly 3ft in diameter. the point of this thread is im trying to figure out how many plants i can fit in there next year (this is my first grow)
below you can see my ghetto drawing. the dotted lines are 3ft sqaures where ide like to put a plant in each sqaure, im not sure which method im going to use yet but im planning on topping a few times, LST, or something to keep the heigth down...the remainder of the cage i want to use to add smaller plants in pots thatll get started later than the other four.
oh btw the ground is HARD AS FUCK. i had to keep soaking it and pounding the hell out of it with a shovel. im going to buy some soil for them cuz this shit here wont work. should i dig them holes? or just dig out the hole 6ft by 6ft area for the four going in the ground.


tell me what you think of my plan so far. anyone got any ideas of something i should/can do different? i want to get as much bud as i can with my limited outdoor space.

damn that pic i drew wont upload but i think you get the idea.

looks like a decent place to grow. and if you can get a lock on that shit you wont need to wory about punk ass kids tryin to jack your shit. only bit of advice i have is to put those pots on a piece of wood or plates, cuz if roots grow out the drainage holes into that sand, and then you try movin the pots you could hurt the babies

lol theres no sand? i figured putting a lock on it would be useless if someone really wanted to jack my shit they could easily hop the fence. the cage is my yard though and about a 10 second run from bedroom but i also have something that should prevent most people from getting any ideas (if they even know whats there)...lol he's pretty big and intimidating to anyone that comes over. i was also thinking of tieing some bells to it so if anyone opens the gate or hops the fence in the middle of the night it'll make noise and alert my beast
