If you don’t like to see any ‘popcorn’ buds in your harvest, you should definitely learn the method of lollipopping. Lollipopping means removing bud sites in the bottom part of the plant because they don’t receive enough light and stay underdeveloped. You’d get better results if the plant directs its energy to the top colas, making them more fat and solid.

Lollipopping non-autoflower plants just before the 12/12 flip is always worth it. Lollipopping autoflowers, on the other hand, is a bit tricky and may actually lead to smaller yields. But rest assured: the quality of the remaining buds will be top-notch.

So read on to learn about the benefits of lollipopping vs not, the right timing, and which bud sites to trim.

The Meaning of Lollipopping

To lollipop means to thin the bottom part of the plant, so that each branch is completely bare down below. Now it only has several nodes on top and resembles a lollipop. Hence the term.

 

These photos give you some idea of why this technique is called lollipopping.
 

Why Do The Lollipopping?

When you grow cannabis indoors, the effective range of the lights you use is limited. The buds at the top receive enough energy to get big and dense, but the flowers in the bottom portion are shaded from the light, or simply out of range.

Note: Even if you use the supplementary side lights, the difference between upper and lower buds is still there. It’s not only the closeness to the lights that matters, but also the position of the bud on the branch. The so-called ‘apex dominance’ makes sure that all the best things go to the tops.

Because of all that, the lower buds stay small and fluffy and have very few trichomes or none at all. When you harvest and dry them, such buds usually have zero bag appeal, low potency, and subpar flavor. It’s best to get rid of them and channel the plant’s energy elsewhere.

Lollipopping should go hand in hand with another thinning technique called pruning. Both are basically the same thing, but to prune means to remove long branches that are shaded by others or make the canopy too thick.

 

SOG (Sea Of Green) And ScrOG

Lollipopping is a great complementary technique with any training method, be it LST or super cropping, but it is a must when you grow marijuana ScrOG-style.

The idea of ScrOG is that you have a flat canopy, with all the buds at an equal distance from the light. However, the canopy in this case gets so dense that anything below the mesh is completely shaded from the light and needs to be trimmed.

 

ScrOG grow

In ScrOG grows, every leaf, bud site, and secondary branch below the mesh need to be removed.
 

And if you grow cannabis in a SOG (sea-of-green) setup, the question of whether to lollipop or not depends on the height of the plants. Often, they are small enough for the lights to penetrate all the way down. So lollipopping isn’t really necessary.

Lollipopping Autoflowers: Benefits And Dangers

For photoperiod varieties grown indoors, lollipopping is a no brainer because photoperiod plants have all the time in the world to recover from stress. As for lollipopping auto strains, you should be much more careful.

If all you value is what’s on the scales, regardless of the quality of the buds, then this method is probably not for you. Lollipopping autoflowers may cause enough stress that the overall yield will decrease. Or not.

To answer this question one should do a side-by-side grow with the same seeds and under the same conditions. The only difference should be whether you trim lower buds or not.

Even if you find out that lollipopping actually led to smaller yields, the quality of the buds would be much more consistent, meaning no larf, only well-formed and solid nuggets.

So, with automatics, lollipopping may lead to the following results:

  • Smaller harvests (hardly noticeable),
  • Better overall bud quality (very much noticeable).

Why Lollipopping Outdoor Plants Isn’t Necessary

Outdoor plants receive light in a totally different way compared to cannabis grown indoors. When the sun travels across the sky, it shines on the plants at different angles. Thus most of the bud sites receive sunlight during the day.

Of course, there’s still some difference between uppermost and lower buds because of the apex dominance (see above), but not enough to make lollipopping outdoor plants really necessary. You should prune lower growth for different reasons though, e.g. to prevent the accumulation of stale air closer to the ground.

How To Do The Lollipopping?

Growers who have done at least a cycle or two usually know how far down the plant they get good-quality buds. This depends on how powerful and penetrating your lights are. So remove any buds that you know would be of inferior quality.

If you have no prior experience, the good rule of thumb is to trim everything in the bottom third of the plant. Some growers even trim away the lower 50%, but in this case the yields would definitely be smaller. Still, it might be a good idea for CFLs, T5s, or other lights with weak penetration. In most other cases don’t get carried away.

KEEP:3-4 nodes at the top5-6+ nodes at the top

The table shows how much foliage, branches, and bud sites you should remove depending on the type of lights you use.
 

You can also do this the other way around: instead of thinking of how much to trim, you can decide on how many nodes you want to keep. Usually, growers keep intact 4-5 nodes from the top. With weaker lights, this can be as little as 3-4 nodes.

How To Cut The Unwanted Growth

You can lollipop by hand or use instruments like scissors or shears. Whatever is more convenient for you.

It’s best to remove a bud site when it’s still small, meaning that the plant hasn’t yet spent too much energy on it. In this case, simply pinching off the bud site with your fingernails is the easiest way.

But if the side shot to be removed is already thick or even woody, use scissors. The scissors should be clean and even sterilized with alcohol if you plan on doing multiple cuts.

 

Lollipopping: Removing The Secondary Growth

This one could develop into a bud, but the grower decided that it was too low on the plant and should go.
 

Start by cutting the fan leaf as close to the stem/branch as possible. Then remove the secondary growth—the future bud site—growing from the node.

Best To Start Before The Flowering Begins

Most growers agree that lollipopping is a rather stressful technique and can slow down growth for a couple of days. It can also hurt yields if you do it wrong. So your goal is to choose the right moment when you do as little damage as possible.

Generally, it’s recommended to start lollipopping at the very end of the vegetative phase. With photoperiod strains, do it 2-3 days before the flip to 12/12. And lollipopping autoflowers should be done when you see the first pistils (female hairs) at the nodes, but before the proper flowers begin to form at the tops.

Later, you may find some leftovers in the bottom third of the plant which you missed. It’s okay to trim them.

Of course, in real life, people often decide to lollipop their plants when they are already in flower and it’s obvious which buds have a potential and should be kept and which should go. So, many growers do their lollipopping in the first week of flower or 2 weeks into flower or even later. For some, it’s a standard practice.

 

If you read cannabis forums, you will find dozens of opinions. Some people say that the first two weeks of flowering is the most vulnerable time. So any lollipopping should be done after that: on week 3, 4. Or even after the plants have finished stretching: on week 5 or 6. Others say that the earlier you’re done with the stress of lollipopping, the better.

Don’t play guessing games! Do the lollipopping before the budding stage even begins. Let your plants focus on flowering and not on recovering from various stresses. Lollipopping in veg requires some forward thinking and skills, but it’s worth it.

Do It All At Once Or Piecemeal?

Whatever causes less stress. When lollipopping autoflowers, it’s safer to trim a little for starters and see how the plants react. If they don’t slow down, you can trim the rest in one go. Or you may decide to do it one fan leaf and one bud site at a time. Please note that in this case your lollipopping will extend well into the flowering stage. And this may actually cause more stress.

No matter what you choose, please remember that any high-stress techniques are meant for vigorous healthy plants. And if the plants are already in shock and won’t grow, leave them alone! At least till they recover.

 

In Conclusion

Though the method of lollipopping autoflowers and photoperiod plants is hardly controversial, there are still many variables and unknowns. So if you have experience with this technique and want to give tips to your fellow-gardeners, please comment below!
