hey there,
I attempted to re-grow my plant i didnt want to see it go to waste, so when it was harvest time i carefully picked all the good stuff, leaving as many leaves as i could, i planted it outdoors in a special place, and it took 3 weeks before any sign of growth, (not great conditions plus getting over stress) as its not getting above 12 hours of light (end of summer) so its starting to bud only at the bottom popcorn buds, so my opinion is this, its time consuming it takes a few weeks to get over the shock, then it will start so i wouldnt attempt to re-grow and waste money (lighting nutes ect) but if its out doors its definatly worth a shot and its not going to waste, and your getting a great plant back in the wild, and it is quite intresting to see how it turns out.
That's bc it's only really worth your time when you put a LOT of time and effort into training them. When you use a method that creates a VERY strong feed system (roots and lower stalk that splits), you'll be able to revert and gain something that you'll never get from a clipping or seed... a resilient system that will only get stronger and more efficient.
Remember... you chop the top, but many of us forget there's a completely different but equally important part under the medium. In my opinion you really need to determine what you aim to do, then assess your gain or loss. Either way, you'll be able to potentially build a stronger root system, and if you use bacteria like Hydroguard... one that is already "cleaned" from contamination of other root systems and other bacteria.
Another thing to consider is that the stronger and wider "feed" branches will actually produce more chutes since it can hold more weight And process/move more internal nutes. The vascular system on the lower part that was untouched can move the food much easier. Plants do this daily, so better vascular system equals better production. Mix that and the better root system and you have a potential for more feeding and better yields. This is partially from experience and partially from education on the subject. Just thought I'd mention, even though This is an old post. Some ppl may find it helpful.
Whatever you do, assess the situation first. Yes you have to wait 3 weeks for regrowth, but if you plan on perpetual grows it kills the agony of dealing with multiple size plants at different stages. If you are set up for clone and grow, then it may be best to stick with that method. It takes up more room but imo It's FAR easier to just switch a group of plants between two sets of lights than having to go through the constant repotting and caretaking of the smaller, more sensitive plants.
I feel if you put the time in to create a good soil environment, it's best to consider it as a separate symbiotic living thing that you "reveg" together. There's situations that it may not be best, but in most cases the benefits outweigh the disadvantages (referring completely to indoor perpetual applications).
