You are going to get many different view points on this.
The facts:
Yes you can regrow. Is it easy, some say yes, some say no lol.
Weed is not a perennial, it’s an annual plant. Basically that means it’s a one and done situation. That’s not to say it cant be done.
Those who do it usually only try it 2 to 3 times with the same plant. Reason is because the trunk and stems get very woody. It opens the plant up to disease and other issues. Also the stems start growing all kinds of funky.
Some people swear by using a regrown indoor plant outdoors. That it already has the root system, and they get huge with big buds.
If your thinking about doing it, and you just harvested without nursing your plant right after the first cut (which needs to be done perfectly & immediately) it’s too late.
High Times mag did a great article on it. This is also a topic on EVERY weed forum out there. Do some research, and see if it’s something you want to try.
