Is Bong Water Good for Plants?

Is Bong Water Good for Plants?

Using a bong is a popular choice for plenty of weed lovers, particularly because it’s less harsh than regular smoking. But a high isn’t all you’re left with after a good sesh – you’ll also find yourself with some leftover bong water. With sustainability becoming an increasingly major focus for many of us, this leftover water can seem a waste. So, it comes as no surprise that we get this question quite a bit – is bong water good for plants?

To put it simply, bong water is not too good for plants. Much like it isn’t good for humans, you shouldn’t be watering plants with bong water. This water contains a whole lot of bacteria, which is why it isn’t so safe for humans and vegetation alike.

Next time you feel tempted to pour that leftover aqua into your plants, think again. You run the risk of damaging the plants and stunting their growth, which no one wants at the end of the day.

But if you can’t put bong water in plants, then what can you do with it? Will bong water kill plants? Does drinking bong water get you high? We’re here to answer any and all of your questions surrounding houseplants and bong water.


Can I Use Bong Water for my Plants?

It’s not a good idea to put bong water (also referred to as bongwater) on plants. It may seem like the noble thing to do with constant reminders around us to take more sustainable steps in our everyday lives, but this is one time you can make an exception. Your plants need several other things in order to grow, and bong water isn’t one of them. Plants need adequate light, air, nutrients, and clean water. And of course a little TLC now and then.Man using bong while woman watches with plants in background

While it’s generally not safe or healthy to put water from bongs in your plants, there is one exception to the exception. As bong water is highly acidic, it can be somewhat beneficial to certain plants that enjoy an acidic soil. These can include azaleas, camellias, and hydrangeas to name a few.

Tread carefully here, though. You should always do prior research to confirm whether those particular plants will respond well to bong water. If it’s a small amount, you could probably throw it into the soil of an acidic-loving plant for a pick-me-up. But don’t go overboard. There’s still a risk that the bongwater can easily damage your plants.

All in all, it’s just best to play it safe and avoid bong water altogether. It isn’t good for humans, plants, animals or anything in-between. Most of the time, it’s also the build-up of resin within the bong that seeps into the water and also makes it unsafe. If you poured this into some soil, it can block the soil’s pores, making it challenging for roots to form.

Oh, and we also can’t forget about the smell. If anything, the smell should be the first thing that deters you from pouring the stuff on your indoor flora. You’ll probably be left with a lingering, putrid stench at all times, making your plants, and you, suffer.

What’s in Bong Water?

Bongwater filters out nasty things like tar, leaving you to inhale the good stuff. This is part of the reason why people lean towards bongs, since they are smoother and less harsh than regular smoking.

After inhaling, the leftover bong water will typically take on a brownish hue, as well as an unpleasant scent. Bong water hosts a myriad of bacteria, making it a breeding ground for mould. It also contains ash and plant matter, which collects at the bottom of the bowl after use.

But that’s not all. Bong water also has remnants of cannabinoids, like THC and CBD. Don’t get too excited, though, because there’s nowhere near enough THC in there to get you high. (We’ll talk more about that later.)

So in summary, bongwater contains a blend of:

  • Ash
  • Plant matter
  • Bacteria
  • Resin
  • Cannabinoids

Each of these substances lends to an unsafe mix for plants and humans alike. Even though marijuana is a plant itself, it’s still not safe to use its leftovers for other plants. This is mainly because of all those extra elements mixed in with the water.


Does Bong Water Help Plants Grow?

Believe it or not, some people do claim that bong water helps their plants flourish quicker and stronger. This is more of a word-of-mouth claim, and isn’t backed by any studies. The idea here is that since the water comes from an existing plant, it can help enrich other plants with its properties. Also, most growers know that plants enjoy soil on the slightly acidic side in the first place, so it isn’t surprising that some people assume the acidity of bongwater would help.

Perhaps a plant may benefit from a slight amount of bong water if it’s extremely dehydrated. But other than that, it’s never a good idea to make it a regular thing.

Plants cannot experience any kind of “high” from this water, so they won’t grow from that. What’s more, bong water will most likely kill your plants anyway. With all that nasty tar buildup and bacteria, this water is more of a hindrance than a help. When provided in even small quantities, bongwater can stunt the growth – and that’s the last thing any green thumb would want.

For plants that thrive in more acidic soil, use a vinegar-water solution instead. Two tablespoons of vinegar to every 4 litres is the best way to water acidic-loving flora.

Here are some other types of water that are safe to use for your plants:

  • Filtered water (best option as the water is pure and free from fluoride)
  • Bottled water (expensive, but an option if you need to)
  • Rainwater (as clean as filtered water, but not always available)
  • Water from the tap (cheapest, but can contain some fluoride)


What Else Can I Do With Dirty Bong Water?

Well, if you can’t water plants with it, and you can’t drink it either, how else can you use bongwater? To be honest, there actually isn’t much you can do with it other than simply throw it out.

The one thing you can do with a little bit of leftover water is use it for composting. There isn’t any solid research to back up this claim, but it’s certainly a known fact that some people use it for compost. It’s thought that the bacteria and other matter can help with the decomposition process within the compost.

You can try it out yourself if you’re curious, but do so slowly and cautiously. You need to have started out with a balanced compost in the first place, otherwise it probably won’t add any benefit.

In essence, just know that it’s okay to dispose of your bongwater. It’s useless, and will actually do more harm than good. As for the best way to get rid of bong water? Outside is best. If that’s not an option, you can pour it down the drain, but the resin can clog the plumbing overtime.


Can You Get High from Drinking Bong Water?

Much like those leftover weed stems from a pack of flower, bong water does not get you high. Weed stems do have a few more uses than the leftover water, but they are both similar in the fact that neither can get you high. There simply just isn’t enough THC content to give you the same effect as if you were to take a regular hit.

Despite there being some leftover traces of THC and CBD in the water, there isn’t enough to provide psychedelic effects.

Apart from that, drinking used bongwater is a bad idea – period. You’ll pretty much get sick instantly from ingesting the water, so steer clear of it at all costs. Maybe if you’re really desperate for a little hydration, you can take a sip, but it’s a terrible idea. You’ll be left with nothing more than a sore stomach and probably a whole lot of regret.


How Often Should I Change Bong Water?

If you’re wanting to get into using bongs, it’s important to know about bong water and when to change it. As well as knowing when to change it by sight, you’ll also be able to tell by how it’s making you feel.

If you’re starting to feel unusual after every hit, then it’s most likely time to switch it up. You’ll see a dark film gather inside the bowl, with black or white specks as well. It’s that resinous build-up that harbours bacteria and mould, which as we’ve said, is bad for both plant and human.

Ideally, you should be changing the water after each session. As Harrison Baum, CEO and founder of Daily High Club, states in an interview with Insider – “You’re literally inhaling through your bong and mould can grow in as quickly as 24 hours.”

“A dirty bong is a health threat, and also can leave a bad impression if you’re smoking socially,” he says. “Don’t be that person who pulls out the dirty bong.”

So, if you’re changing the water after each session, does that then mean you can use it for watering plants? Well, it’s better than old bongwater. But it still isn’t a good thing to do, and still runs the risk of damaging your plants.


Final Thoughts

Is bong water good for plants? No, it isn’t. Perhaps you could use a little if your plants are really desperate, but it’s not going to have the best effect on their health. It will mess with the natural pH levels of your flora, leading to unhealthy and unhappy plants. Disposing of your bongwater is also important for your own health. It prevents a build-up of toxic resin, so make sure you’re changing it out after every session. But most importantly – what are you smoking in your bong?
