I only have one run of SSH under my belt right now, but it is surely a really nice plant!
I would suggest some creative bending and tying. I do this with strains when I have the time, and usually get higher yields than if I had had just let them shoot up or top them(NOTE: I have not yet done this with SSH, did it with everything else from NH to indicas, as I like to let the first grow of a new strain flower without interference from me such as topping or bending.)
The main benefits to training and tying are increased yield, without the small stunt that topping produces. Indeed you can basically turn all your nodes into cola producing branches instead of small bottom buds.
I would suggest one of two things if you plan to go with this method.
It appears your containers are hard platic. If so, take and drill a small hole just under the lip of the container. I use floral wire(green plastic coated so it will not rust up the plants). If you are going to use string, I would suggest tying loosely around the stem as it will increase in diameter. Thats another good thing about wire, you can make a loop around the stem that has space in it and still keep tension in the wire.
Next, just gently bend the plant over so it is just a little bit beyond parallell with the medium, and tie or wire it in place so it cannot spring back up.
This will cause a hormonal shift to the rest of the plant, causing all those developed side braches to shoot straight for the sky, increasing your tops, and decreasing those tiny buds that are such a pain in the ass.
Personally when I do this I like to plant the plant in one corner of the container, and tie down to the opposite side, so that the plants are more centered in their pots after the tying(as an aside, I have recently thought about cutting the growth tip off after tying, sticking it into the medium to root, and not needing the wire, but thats another topic) I also use soft plastic grow bags, so I put a bamboo stake in the planter opposite the plant, and tie to that. I have tried tying directly to the grow bags by putting clear tape on the bag, and then a hole in the the tape and the wire through the whole, but stakes are damn cheap and much easier to stick into the dirt
