No new growth will develop from the growth tip that has been cut. This allows the lower lateral growth to assume the dominance. Since there are two growth tips at each node, you effectively double the number of dominant growth tips every time that you top the plant.
You may top the plant to the 6 th node as the seventh node is emerging by carefully removing the growth tip just above where two new shoots are forming.
If you top lower than the 6 th , you are going to be cutting away a significant portion of the upper growth on a plant see pictures. This is the aspect that can be hard for new growers to accept. We nurture our little seedlings and then we chop off their heads! The actual act of topping is incredibly simple. Take a pair of pruning snips and snip off the growth tip. To further reduce the possibility of infection, we recommend that you sterilize your snips before using them to top.
This can be done with heat boiling water or open flame , but let the snips cool again before use. We recommend topping high on the stem, rather than just above the node. Topping low, requires removing significant growth. However, if the plant is not topped it will put all of its energy into the one main top. By topping it, I now have two main growth tips! This may make you feel like it is setting you back, however, look at this plant just 6 days later… It is twice the plant it used to be!
Topping is a wonderful plant training practice on its own. It is also a key aspect of other training strategies. The plants pictured in this tutorial are topped in preparation for mainline and manifold training.

The Science and Practice of Growing Cannabis. Want to know more about grow lights? Our grow light guide is one of our most extensive and innovative tools for growers yet! Our goals are to demystify grow light metrics, share reliable grow light data and empower home growers with the best information about grow lights. We conduct independent grow light testing and have developed articles and resources to help growers understand the science of horticultural lighting.
In this video, Dr. Coco tests one and two of the new Mars-Hydro SPs in different coverage areas. Coco explains all the key metrics and shows how we use them to test and evaluate grow lights. We hope that all growers will find the video interesting, regardless of how much experience you have with grow light physics! Need equipment for your grow? At Coco for Cannabis, we curated a list for all of your growing needs! We put the grower's interests first and only recommend products that we use, trust, and consider to be a good value.
From finding the right grow light and equipment for setting-up your grow space , to curing, harvesting, and storing your final buds, our product and equipment guide has everything you need to set up or upgrade your grow!

Basically, topping refers to the act off removing the main shoot of the cannabis plant.
Prior to topping, the plant uses all of its energy to growing the main shoot. Once the shoot is removed, no new one will ever grow from that spot, and the energy is diverted to the smaller side shoots. As a result, the plant does not grow into a triangular shape like a Christmas tree, with just the single large shoot in the middle. Instead it grows into an inverted triangular shape, with more bud sites at the top of the plant where they get exposed to more of the grow lights.
Topping also results in the development of two new colas at the top where the plant was topped. Fimming is very similar to topping, but slightly different. When topping, you cut the shoot between the nodes. When fimming, you cut any new growth off at the top of the plant, not further down between the nodes. This stems from the fact that a fimmed plant looks like someone tried to top it, but did so incorrectly. Fimming does not reduce vertical growth as much as topping, but it also does not take as long for the plant to recover.
After fimming, the plant grows four colas at the cut site, instead of two with topping. Overall, topping usually gives better results, since fimming is a bit of a hit or miss proposition. Sometimes it works well and sometimes it does not. The biggest advantage of topping was already mentioned above: instead of growing into a triangular shape, the plant grows into an inverted triangular shape.
This means a wide, flat top with many colas that are all exposed to the light. This provides a huge boost to yields when growing indoors, where the light source is stationary above the plants. Another advantage is that the plant does not grow as tall. Topping keeps their height in check. The biggest disadvantage is that weed plants need time to recover from topping. This means a longer vegetative growth stage. The more often you top, the longer this stage takes. Expect a week minimum vegetative growth phase if you plan on applying these techniques.
Another problem is that having more colas i. Always top during vegging. Topping seedlings risks killing them or, at the very least, stunting their growth.
Doing it during flowering will also damage your plants. It is best to top your weed plants after they have grown 3 to 5 nodes. Once they have reached this size, they are strong enough to recover from the shock of being cut.
If you want to top the new growth again, you should wait at least a week, perhaps 2, to give you plant time to recover from the previous topping. Log in. Install the app. Contact us. Close Menu.

Thread starter rct Start date May 20, I am just wondering if I should top my plant? I am on my first go around and they are at about 4 or 5 nodes. I am just curious when or if I even should. These are all 3 of the ones I am growing right now and that's all I am growing atm. Chris Scorpio New Member.
What strain are they Mag7 Well-Known Member. I would, but that's just me. Keir Stama Well-Known Member. Scorpio said:. Click to expand I believe they are gorilla glue and where would I cut it at the middle like in the picture?
Obi Wan Well-Known Member. The image below depicts where to top between the nodes:. A couple more pics from one of my toppings:.
