Which strains DO NOT respond well to topping?

Had several DC plants that wouldn't bush to save their lives.
Bean poles, basically. Waited three months for one, all it did was get incredibly leafy around mainstem, couldn't clone it, so had to just run it and let her go.

trick question they all respond well to topping they just take different times to respond.

One time I topped something I forgot but what but it keeled o0ver and died lololo.... only time that happened tho :D

I just topped a few more. One I didn't top because it looked so perfect and had some side branches already.

"apical meristem. A meristem at the tip of a plant shoot or root that produces auxin and causes the shoot or root to increase in length"


I have the impression that the Auxin is the hormone that inhibits nearby nodes from growing their little nubby sprouts (the plant parts that become side branches).


I think different strains handle and secrete auxin differently.


One of the debates I've been having with a neighbor who grows is, after topping, as new branches establish themselves, does it promote yield to trim a percentage of growing tips ?

If they are creating auxin and that is inhibiting side-branching in nearby sprouts, then I can see a reason to trim even some of the main side-branch tips, during a longer term grow like a summer grow.


I don't normally trim side branches but I might try it next summer, try and get a side by side with 2 near identical clones.


I don't know of any strains that don't like topping.


One alternative is to bend the plant over. That seems to encourage lateral growth.

LST is interesting, If you get enough light to the lowest nodes you can get solid buds that develop and finish with the main cola.
If you want to get a better yield in a hurry with little veg, LSTing a plant over is a better choice than topping. Utilize all available branches and let the hormones stack that main cola.

Exactly correct in my opinion. Some also just need training combined with topping to get them to bush.

I also agree with this statement. I am a big fan of topping and topping early. I usually top a plant 1-3x depending on strain, veg time, and bloom constraints. I have done a side-by-side comparison, with topped and untapped plants.. the topped plants always tend to yield more.

FWIW I see all kinds of shit in strain descriptions! If I seen topping not advised I would read between the lines and think might be some hermie issues/unstable line to look out for, i have seen plant intersex from topping stress or also throw reveg type single blade leaves in some strains.

A good training and some recovery time before flower is best.

Pre 98 bubba, once topped it will still try to form a single cola dominant plant. The only way I could ever get it to bush out is by topping it about 100 times all over the place and giving it an extremely long veg.

Nirvana's Blue Mystic and a blueberry pheno of Chimera Ultimix didn't do well with topping. There may have been other factors, but I haven't had problems topping anything else, so...

Define, didn't do well though, do they stop growin or? slow response time? When I top sour B it takes forever to get a response time but the end result is always better, a busher plant with more main growing tips.

Another advantage I like to topping very early, like the first few nodes is it causes the stems to thicken very quickly and lets the seedling stand on its own, a slight advantage sometimes.

"Didn't do well", like, it didn't improve the plant. The 2 blueberries I mentioned also took a long time to recover from FIM, which is what I do. Th result was smaller yield than if I l'd left them alone.

Topping is fine but I think with the lower yielding types of kush style plants that are so popular right now, this is the right answer. I just bend them, tie down and grow them sideways .... can get a huge yield from many plants this way.

Yes.

another observation from my notebooks, topping very early at the first few nodes usually avoids "reveg" stress that can occur from vigorous toppng of older plats, ie a plant can drop the number of fingers in leaves it throws, ive seen 3 and even single reveg leaves.
When I top early they still just throw regular sets and keep pumping, from my notes response to topping (branch shooting and leaf set)is generally faster at a young age.

well I don't know about what I or others said before, have some back tracking to do as they say, but the topping seemed to work just fine as would have not topping or any technique. Things are ready to flower 2 weeks ago and despite the neglect under a 4 ft flo, it looks like a lush rainforest, so all hail ebb and flow hydro!!
