Three tubs and you’re a farmer…sort of

There’s a moment that happens to a lot of people at some point.

You’re standing in a garden centre and you think, “I could grow some veg.”

Fast forward a week and you’ve got three tubs on the patio, a packet of seeds, and a level of optimism that suggests you’re about to become fully self sufficient by Tuesday and be the lead in a remake of The Good Life (showing my age there).

Reality is slightly different.

But here’s the thing. Growing even a small amount of your own food, even just three tubs, actually does have an impact. Not in a dramatic, save the planet overnight kind of way. But in a small, meaningful, surprisingly satisfying way.

So, let’s look at it properly. What difference does it really make? And is it worth the effort?

What are we talking about here?

Nothing extreme. Three tubs might mean a couple of tomato plants, some herbs like basil or parsley and maybe lettuce, spinach, or spring onions. You don’t need a garden. A balcony, windowsill, or small outdoor space is enough. This isn’t farming. This is dipping your toe in.

The big win. Cutting out food miles

One of the clearest environmental benefits is transport. Most supermarket veg has travelled. Sometimes a little, sometimes a lot.

Your home-grown tomatoes, on the other hand, have travelled approximately zero miles. Unless you count the journey from the tub to your kitchen, which is usually measured in steps rather than miles.

Transport emissions are only part of a food’s footprint but removing them entirely is still a win.

Less packaging, less waste

Supermarket veg often comes wrapped, bagged, or boxed. Your home grown veg comes in… well, nothing, other than a smattering of compost.

No plastic. No labels. No tray you feel slightly guilty about throwing away. Yes, you’ve bought the tubs but they’ll last you years.

It’s a small shift, but over time it reduces waste.

Fresher food, less food waste

Here’s something people don’t always think about. Home grown food tends to get eaten. Why? Because you’ve watched it grow. You’ve watered it. You’ve probably spoken to it at some point. If they spoke back to you then we need to talk about getting you some support.

You’re not letting that tomato go mushy at the back of the fridge. Absolutely not.

That means less food waste, which is a bigger environmental issue than most people realise.

A quiet connection to what you eat

This isn’t strictly environmental, but it matters.

Growing even a small amount of food changes how you think about it. You start to notice seasons and how long things take to grow. And yes, how much effort goes into producing food, especially those moments when you are stood out in the dark in your pyjamas, torch in hand, picking slugs off your precious seedlings.

That awareness often leads to better choices elsewhere, even outside your three tubs.

Ok, but let’s keep it real

Before we all start building raised beds and naming our courgettes, there are a few downsides to consider.

It won’t replace your weekly shop

Three tubs aren’t going to feed you. At best, you’ll supplement what you buy. A handful of tomatoes here, some herbs there. So, in terms of total environmental impact, it’s relatively small. This is not about replacing supermarket food. It’s about adding something extra.

Water and resources still matter

Growing at home isn’t impact free. You’ll use water, compost and containers. If you’re buying plastic tubs, peat-based compost (please don’t), and watering heavily, the environmental benefits can shrink a bit.

That doesn’t cancel it out. It just means it’s worth being mindful.

The temptation to overdo it

This is a classic. You start with three tubs. Next thing you know, you’ve bought ten more containers, got a tractor on order and seeds for vegetables you don’t even like. And suddenly your “simple” project has a footprint of its own. Keeping it small is actually part of what makes it sustainable.

So what’s the actual impact?

Let’s be honest. Three tubs of veg are not going to dramatically reduce your carbon footprint. But they do cut out some transport emissions, reduce a bit of packaging, lower a bit of food waste and shift your habits and awareness.

And that last one is the real kicker. Because once you start paying attention to food in this way, it often spills into other choices.

What makes the biggest difference?

If you want to get the most out of your three tubs, a few simple things help. Use what you grow. That sounds obvious, but it’s the most important part.

Grow things you actually like eating. There’s no point growing kale if you’re not going to touch it. Courgettes will grow by the tonne but no good if you can’t stand them.

Keep it low effort. The easier it is, the more likely you are to stick with it. And don’t stress about getting it perfect. A slightly wonky tomato is just as delicious.

The unexpected benefits

Something else tends to happen when people start growing even a tiny bit of food.

They enjoy it.

It becomes a small daily ritual and a reason to step outside. Again, not strictly environmental. But it makes the habit stick, which is what really matters.

Three tubs of vegetables won’t change the world. But they might change how you think about food. And that shift. That awareness. That small habit. That’s where the real impact starts.

So if you’ve been thinking about it, give it a go. Worst case, you end up with a slightly sad looking plant and a good story. Best case, you grow something, eat it, and realise you’ve taken a small step towards doing things differently.

And that’s more than enough.
