Yo, it’s Dan and I’m here to talk to y’all about how to get the dankest yield from your cannabis plants. Whether you got one or many, the goal is to produce the heaviest buds possible. And to do that, you need to use a high-yield training technique in your garden. There are a lot of techniques out there, but today we gonna focus on two: topping and FIM.
Topping is when you cut off the top bud of your plant so that two new branches can grow and promote lateral growth from lower limbs. This technique helps promote lateral growth, reduce plant height, and increase yield in select varieties. It also helps control the cannabis canopy and promote light penetration to lower branches. If you don’t have a lot of space or can’t grow too many plants, topping is a great way to get the most out of what you got.
FIM, which stands for Fuck, I Missed (a name that speaks for itself), is a technique that’s similar to topping. It was reportedly invented by a grower who accidentally cut off half of the top bud while topping their plant. FIMing generates four axillary (lateral) buds and removes apical dominance. Like topping, it promotes lateral growth, reduces plant height, and increases yield in select varieties. The primary reason why you would choose FIM over topping is if you want more than two primary axillary branches.
Now that we know what these techniques are, let’s talk about when to use them. You should top or FIM your plants during the vegetative stage once they exhibit 3-5 nodes, which is usually 20-30 days after seed germination. If you do it earlier than that, your plants may have a hard time recovering. Once you’ve topped or FIM’d your plants, give them a minimum of 1-2 weeks before doing it again.
So how do you actually top or FIM your plants? Let me break it down for y’all.
For topping, you’ll need feminized or autoflowering cannabis plants, precision trimming scissors, and isopropyl alcohol. First things first, set up a work space and sanitize it properly. Then locate the upper-most node (aka the terminal bud) and cut off the stem using your trimming scissors. Let the cut area heal for 48 hours before deciding whether to top again or not.
For FIMing, set up your work space and locate the terminal bud like you would for topping. Instead of cutting off the entire bud though, gently hold the uppermost part of it and snip half of the primordial leaves. Let the plant heal for 2-4 days before deciding whether to FIM again or move on to another technique.
Remember y’all, these techniques are high-stress training methods that can stunt your plant’s growth for a little while. But with some patience and care during recovery time, you’ll end up with some seriously dank buds that’ll have you drooling in no time.
So go forth and get those bud trimmers ready – it’s harvest time!
