Does topping your plant cause the taproot to stop growing?

I've heard from a couple of different sources that when you top your plant it causes the taproot to stop growing (and the only roots that continue to grow are the rootlets coming from the taproot). Can anybody either confirm or refute this? I've only recently heard this and it's putting doubt in my mind about when to top.

Nonsense otherwise all growers will be growing their plants in solo cups harvesting buckets ..lol

chill!

good luck

Makes you wonder where some of these people get these theories. And why the fuck they put it out there as fact. Thanks vostok

lol --> actually it's kind of the opposite. When you top the plant its growth above ground slows while it's adjusting its focus to the branches that remain. (12-14 days) meanwhile the root system continues to develop into a larger more developed root mass. The only thing stopping roots from developing is either poor soil, lockout, or root pruning during transplant. But after transplant those roots will explode with high growth. Just give it time to get past the stress before flowering.

No

Thanks Goldberg. Would you say it's best to top/fim before they are transplanted into their final pots though? And if so, how long after transplanting into the final pots should I wait before flipping to flowering?

You have to do what ever you choose to do at the right time. One has nothing to do with the other. They all effect the plant and its growth. After any topping, fimming, transplanting or any other form of training. You must allow time for the plant to recover. How will you know when it's time you ask? That's easy. When the ENTIRE plant has returned full vegetive growth. Any branch or stem that isn't growing at full speed at the time you flip the lights will NEVER fully catch up. It will still flower but the flowers will either be smaller or more popcornish. Because the other branches will stretch further than the others and they'll grow right over the smaller slower branches. Then you might as well cut them off since the plant itself is going to concentrate on the stronger taller branches anyway.
