If you are new to hydroponics and want a simple way to grow food at home, this site will help you start small, choose a setup that suits your space and your budget, and avoid the sort of first purchase you later regret.
Hydroponics only means growing plants in water instead of soil, and it can be as small as a jar on a windowsill. The goal is not to build everything at once. It is to choose well, keep it manageable, and get to a first harvest worth putting on a plate.
Start with the space you actually have, and how much of it you are willing to give up. Everything else follows from that.
A corner of a roomRoom for one proper system on a shelf or a stand. This is where most people start, and leafy greens do well in it from the first crop.Compare the system types
A spare room, cupboard or tentMore space and more control, but more to manage. Heat, airflow and noise matter more here than the system itself does.Set up a room or a tent
A garden or a greenhouseFree light, and weather to work around. Simple systems still do the job outdoors, and you can start with very little.Growing outdoors

Systems sit on a shelf or stack upwards, so a small footprint can still hold a useful number of plants.

The water circulates rather than draining away into the ground, so a home system gets much more out of every litre.

You decide the light, the feed and the temperature, and once a small system is running it needs only a few minutes of attention a week.

I'm Charlie. I have an official qualification in hydroponic cultivation, I run the Everything Hydroponics YouTube channel, and I have advised and taught a lot of new and existing growers. I am a teacher before I am anything else, so what you read here is backed by peer reviewed research and written to be understood rather than to sound clever.
I will also tell you when something is wrong for your situation. If your space, your budget or your back rules a system out, that is worth knowing before you buy it rather than after. A list of the ten best kits can never say that. More about me.
