here is the steps:
Welcome to DIY & GARDEN
Today I’m going to show you How to design and build an inexpensive system for growing plants in water.
Everything you need to know to start hydroponic garden
From building the system, starting seeds, plants nutrients and system maintenance.
Let’s Get Started
You will need 55-gallon plastic barrel a popular low-cost option.
There is a line in the centre of the barrel, Mark that line
These barrel are thick, you will need jigsaw or other power saw to cut them.
Wash and clean the barrel
You will need a foam boards to use them as Floating raft.
these foam boards can be cut to any shape
Measure and cut the board into rectangular 1Ft x 2 Ft.
Most leafy greens are grown with 6" spacing in hydroponic systems.
Brush away any loose foam pieces from the cut edge
Next drill a 55 mm hole
If you don’t have drill, you can use a knife to make the holes.
@DIYGARDENWITHBB
Drill all the boards, make sure the end holes not side by side
Use bricks to fix and stabilize the tanks
Fill the reservoir with water
You will need an Air pump, air stones, airline tubing ,4 mm Tee.
Air pump specification I’m using
Next cut two Pcs from the pipe each 3 Ft long, then connect them to the air stones and the tee
Connect the TEE to the pipe then to Air pump.
Put the stones in the water and turn on the air pump.
Add the foam boards
Adding Nutrient Solution
Add fertilizer (A & B) in small increments to avoid over fertilizing.
Check the EC after adding fertilizer and continue adding small amounts of fertilizer until the target EC is reached
Stir the reservoir to circulate the nutrient solution to disperse
the concentrated fertilizer after each addition
Measure the pH after reaching the target EC. Add pH down or pH up in small increments
Slowly adjust the pH until the meter readings are within the target range.
Net pots can be square or circular and generally range from 2 to 10 inches wide.
2- and 3-inch net pots, the most commonly used net pot sizes in DIY hydroponic systems.
Or simply you can use plastic cups, cut off the base.
Starting seeds
You need plastic plant pot, stretch wrap and seeds
Fill the pot with coco peat
Then Wet the coco peat
Sow the seeds, water
Use stretch wrap and cover the seeds
Most leafy greens can be grown in this system from transplant to harvest without any maintenance of the system.
Place the 2" net pots into the 2" holes in the raft.
Make sure the raft size so it comfortably fits inside the reservoir.
This design can be used as a model for smaller or larger floating raft gardens.
• Suitable Locations: Indoors, outdoors, or greenhouse
• Size: Small to large
Adding an air pump improve plant growth and reduce the risk of root rot
