How to build your own Hydroponic Kit
Building your own Hydroponic system at home is very easy and a lot of fun.
All you will need are 3 items:
- The tank
- An hydroponic air pump
- Planting cups & sponges
Of course in addition you will also need plants to grow and the right type of plant food to add to the water.
The DIY hydroponic plan video shows how I build my own hydroponic system at home, taking less than 1 hour.
The DIY Hydroponic Plan
Taking the 3 items in turn:
Item 1 – the tank
The reason I built the hydroponic system was to grow Roma tomatoes and Cayenne Peppers indoors.
Especialy Tomato plants can grow up to 1 to 1.5m tall
i.e. most of the small hydroponic units you buy are not suited as they are often designed for herbs & maybe lettuce.
Which is why I made my own hydroponic tank – all I did was buy a 29 litre plastic storage container in a DIY shop and then drill the holes in the top.
Yes, you can buy containers on Amazon but they are often cheaper in DIY shops or even supermarkets.
Item 2 – the hydroponic air pump
Within an hydroponic system you will need to provide your plants with air – to help them grow.
The pump in this plan was specially selected for 2 main reasons:
- It’s very quiet – many hydroponic pumps tend to be noisy, whereas this pump (maybe because it’s designed for living room aquariums) is very quiet.
- Adjustable air flow – you will need to adjust the airflow depending on the size of tank. For a 29 litre tank just switch it to it’s lowest adjustment.
Item 3 – The planting cups & sponge
You will need these to put in the lid of your container.
When drilling your holes in the top of your tank:
- Make a note of the top inner diameter of the cups you use.
- The holes in the video were 31 cm in diameter, but check your cups before drilling.
In the video you will see I only used 6 i.e. you will have lots left over for future use.
The total cost of the DIY hydroponic plan
The cost for the unit was for me:
- The tank + lid = £4 (was on special offer)
- Hydroponic air pump = £12.99
- Cups & Sponge = £2 (ok total cost is more but only used 6)
- i.e. Total cost = £18.99
Please note this is an estimate but substantially lower than virtually any other ready made kit you can buy.
Make your own hydroponic unit or buy one ready made?
It a fun project to do but has some advantage & disadvantages:
- It is quite easy to do
- A lot cheaper than buying a ready made hydroponic kit
- Will give you hands-on practical experience of managing an hydroponic system
- And of course – your plants should grow faster with better yields (especially if you also use a grow light)
- The clear plastic could result in algae growth – replace the water if it gets bad
- Depending on what you grow you might need to find a way of supporting your plants.
- Not as ‘professional looking’ as the ready made kits.
It is very early days, the kit has only just been made and will have to see the results. I will update this page over the following months.
On the other hand the ready made kits are easy to use and have been proven to work.
