hi mate,
its good to see you got that set up sorted, looks like a great setup and should work very well indeed.
with any sory of training like topping/defol/hst etc etc their is always going to be some recovery time, now if your grow conditions are spot on and everything is within a good range then recovery time will be a matter of a couple of days, but if you have a problem crop up which happens to all of us at some time or another then this can put you back a week or more so get the grow conditions right and then you will have no problems using hst, it really pays off once everything is working well, from my own experince it can really stunt growth if some other problem crops up while your doing the training,
but at the end of the day its your plant and your grow, you do whats best for you mate. i jumped in feet first and learned the hard way, my grow conditions wasnt spot on and i did a fim or topped and growth stopped for a week or more, the plant was just not growing well enough to recover from the damage caused so took me much longer to grow, now my grow conditions are ok and i can pretty much do what i like to the plants and they bounce back pretty quick, but it took me a couple of years to know the plants and get my room the best i can get it,
