How do I harvest cannabis?

In the video below, our Horticulturalist Stephen, shows us exactly what you need to do once your grow is finished and how to harvest! 

(0:00) Hi, my name is Stephen Campbell here at Grobo headquarters and these are my scissors. 

(Take 2)

(0:07) Hi everyone, Stephen Campbell with Grobo, I’m the horticulturalist here. Today we’re going to harvest one of our Grobo-grown plants. This is a Sweet Tooth, an Auto Sweet Tooth by Canuck Seeds. It’s been growing in this Grobo for exactly 70 days under a full spectrum. This is a much lower yield than I’ve been seeing in Grobos usually because we we’re doing our spectrum test in this and instead of adjusting to the conditions that I saw growing I kind of had to leave them the same. 

(Cutting). (0:37) This first thing that I want to do is I want to pull off all of the fan leaves because they don’t have any medicine on them at all. So I’m going to snip those off like this, straight into the garbage. Some people save these, you can use them for juicing. They have a lot of antioxidants in them, but there is very little CBD or THC. So for most growers these are just trash. 

(Cutting). (1:06) The next level I’m going to look at is called the Sweet Leaf. When you look at the bud really closely, I’m going to get rid of this last fan leaf, you can see there are very little crystals on that one so that one is going to go. But if I take this one for example, you can start to see that there are some crystals on that. So just like very close to the bud here all these Sweet Leaves around the bud which do have terpenes and crystals on them. We’re going to save those and those are going to be used to make oil or concentrates or you can cook with those as well. Some of these on the bottom, some of the smaller buds, we call that in the growers vernacular LARF or Popcorn Bud. Those I’m going to snip off as well and these 4 smaller buds are going to go into my Sweet Leaf, which again I make a concentrate or an edible out of. I’m going to save the very top bud here to dry and then I can use that to either smoke or vape with. So these bottom ones I’m going to pull right off like this. And this one is pretty close, it’s nice and dense, you could maybe get a nug out of that one. Then what I do is I just take off all that Sweet Leaf. Basically what you’re doing now is giving the bud a haircut. You can go in if you can and pull off each individual leaf, it’s a little more time consuming, or you can just go in and give it that nice little haircut. What you’re really looking to do here is get rid of all the leaf and just leave the calyx and the nice bud behind. Once I’m done I usually give it a little tap and there’s a bud that I’ll hang up to dry. So my first one’s done. Again on this one it’s really easy to see where the fan leaves are and you can even just pull those backwards and they’ll come straight off for you. On average you can probably expect to spend about 30 minutes doing your first couple of harvests in a Grobo, maybe a bit longer. 

(3:14) The drying process is really interesting to me, we dry it by hanging it upside down, merely for convenience and because it’s easy to do. Once the outside of the plant has dried for a couple days, we put it into those glass containers and what happens is all the moisture that’s left in the stem then comes out and increases the humidity in that glass jar and it really starts to cure the buds really nicely. 

(3:41) So we’ll do a wet weight of both the buds that we have left over that are A quality buds and we’ll also weigh our Sweet Leaf here that we can save and save up for another product. 

(3:53) So those roots look nice and white, they’re a little off-brown which is because of the nutrients. No root rot evident, you can see it looks like a big carrot stalk almost. (Weighing. “Come on guys”). 72 grams. (48 grams).
