Yes. I'm currently working with Tiresias Mist. It works, if you follow the instructions it will work. The first try I started spraying a single branch the same day I put the plant into 12/12. I focused specifically on the stem of the branch and not the leaves. At first you will see a few female parts appear. But soon after, male parts begin to appear in abundance. I continued spraying the stem after the male parts appeared for about a total of 30 days. This stem produced plenty of pollen. However, the female being reversed was too far along to pollenate and allow time for seeds to develop. So I recommend adding another female to the 12/12 after the plant being reversed has been in there for two weeks. That way when the pollen is produced, there will be a female to pollenate that isn't already at the end of it's life cycle. The pollen was used to pollenate a clone of the same strain plus some others. At this point the seeds are just now splitting their bracts. I should be harvesting soon and will report back on the results.
The second experiment I followed the instructions more exactly, starting to spray during veg about 5 days prior to entering 12/12. Then after about 21 days I stopped spraying (even though there wasn't clear male parts showing). This plant too produced pollen but less than the first (oversprayed) plant. So I recommend spraying until you see male parts, then stop. I will report back with results on these experiments soon.
