Iron Scrog method of growing can be a great way to utilize your area and get pretty much the best results as you have one main canopy,
How to start is get 2 - 4 plants going training them around your pot this can be done by either coat hangers string anything to actually keep plant low, next step is to super crop this is pinching all tops this will create many new tops and that is pretty much it as new growth comes up keep pinching and bending tops outwards before you know it you got a plant that has lots of bud sites ,
now you need to make a scrog table usually it is good practice to make min 3"x 3" squares not only will this table help hold buds in there it is also a support as buds get bigger plant buds want and will want to bend over cause there top heavy so its a win win situation , so as plants grow into table all your doing is super cropping and bending plants outwards moving it over to next square and so on till table is 3/4 full then its time to flip to flower ,
now you should for the first 10 days still super crop tops and fill in the remainding squares keep stretching plants all over
this also will help in the stretch phase key is to have a even canopy not let plants blow up all over if you have to raise table what ever to keep all tops even with canopy,
Now your in full flower there is no need to have anything really growing below the table so now you need to prune all the lower bud sites and leaf off plants as there in shaded area , usually you will trim 1/3 rd of plant and keep maintaining it as lower sucker buds will want to form very important to keep clipping them off as all there doing is taking away energy from top bud development
Other then that that is pretty much it probably take one or two scrog grows till you get it figured out, but once you get it you will be in awe at the amount of bud sites that all are litterally same size nice big ones
