Well when it starts bumping the lights get some jute or cotton string and start tying it over. I do not have a green thumb or a degree in injuneering so I grow in Hempy Buckets. I drill holes in the top edge of the buckets just so to have an anchor point to tie the cord. Guess it would be called HST but have never managed to lose one over the procedure as of up until this time. Knocking on wood Now I have never grown that particular variety of medicinal herb of which you speak, but fairly sure they all have a big growth spurt when they get fresh and strong into the bloom phase. Once it doubles or triples in size compared to how big it got in veg, it will suddenly stop getting any taller. Start tying them over whenever needed. You can supposedly cut the string after a week. Sometimes it stays put and sometimes it dont.
