Deep Water Floating Bed Construction – Aquaponics

Build a floating aquaponics raft to grow lettuce in your yard.

This video shows how to build a Deep Water Floating Raft for aquaponics. I am building using Dow blue 2″ foam board from Lowes. It costs about $32 per sheet, but is what has been recommended online for being safe to use in aquaponics. Here are the net pots & hole saw I am using in the video: 2” net pots – 2” hole saw – The first step is to size up your foam board to the area it is going. Cut about halfway into the board, then it will snap right off cleanly. The next step is to measure about 6-10 inches apart for the net pots, drill through the board with any size drill bit. Use the hole saw to drill both sides of the board, push the board until it pops out the hole. You can now fill with the net pot, fill up the cups with lava rock / perlite / clay pepples, or nothing & you can grow! Thanks for watching!

Make an easy $100 with Aquaponics

 Easy way to produce plants locally.

I just got done removing $100 worth of plants from my 1 gallon perlite pots that have been sitting in my aquaponics bed. I grew ~7 new Triple Crown Thornless blackberry plants, if you were to buy brand new would cost at least $10 per plant. I had 3 goji berry plants & 6 Black Elderberry plants grow as well. Easy way to get $100 of plants for barely any time spent. Here is how to do it, #1 Fill up a plastic pot with perlite (might have to block the holes at the bottom with big rocks). #2 Place that pot in your aquaponics bed, which allows the water to wick upwards. #3 Cut 6-9″ pieces and stick them ~ halfway into the perlite. You can easily do this with thornless blackberry, elderberry, hydrangea & goji berry. You would need to research on other plants. #4 Wait a few months and you have a brand new rooted plant. You can pot them, or plant them straight into the garden.

Wicking Bed

Aquaponics Wicking Bed Build

Continuing on with my stocktank aquaponics build. Today I finished one of the wicking beds. The bottom layer is lava rock, then 2 inches of perlite & top it off with soil.
The water pipe goes down a drain pipe to the bottom layer. The drain is surrounded by a 1 gallon plastic pot with slits cut in it.
I started sunflower seeds on this, hoping to get some microgreens. I covered the top with plastic to help germinate those.

Big And Small Goldfish Intro. for Stock Tank Aquaponics | Farming Seattle

This episode, I show all of my progress on the Stock Tank Aquaponics system. I had to do a few things in order to get ready for the goldfish.

1. Added 6 legs to each end of the grow bed. Since this bed is over 1000lbs I didn’t want it to crack the stock tank. I added 4×4 legs that were braced with 2×4’s and wood screws.

2. Going to install a bigger bell siphon intake valve, after some guidance it seemed a lot better to have a 1″ inner pipe on the bell siphon since the bed will be holding a lot more water. In my next video i’ll show that installation.

3. Added outdoor electrical plug, this allowed easy wiring for the pond pump, only 20ft away from the outlet.

4. Added Goldfish! Bought 20 small / 20 large feeder goldfish ~ $10. I set these guys in the water for ~10 minutes (should have been 30). Some seemed shocked, I think next time I will do the full 30 minutes, then slowly add the aquaponics water.

Lava Rock Grow Bed Construction

 Continuing with my 300 Gallon Stock Tank Aquaponics system.

This video shows finishing up the grow bed which involves washing a lot of lava rock, installing a uni-seal, bell siphon & putting the pond liner in place.


Products used in video:
1″ Banjoo PVC Bulkhead
2 1/4″ Hole Saw
Pond Liner 13×10:
How to wash lavarock – Drill a bunch of holes in a bucket, load some lava rock & dunk that bucket and rock in a garbage can full of water. Do this 3-4 times while rocking the bucket while the water drains. At the end, rinse with a hose to clear out as much lava sand as possible.
Drill a hole with the holesaw, clean it up with the rasp & razor blade. Put the rubber pond liner down over the hole & cut a clean hole with the razor blade.
Next, you will want to arrange the pond liner so that it is pushed against the bed, then load in washed lava rock to the top. You might want to test your bell siphon before fully loaded.
Bell siphon – I’m using a 1″ PVC pipe about 10″ tall, with a 2″ PVC and cap about ~12″ tall with holes drilled at the very bottom. I will probably need to do some adjustment because it wasn’t siphoning very well.

Stock Tank Aquaponics, Grow Bed Construction

Stock Tank Aquaponics grow bed.

This bed is 6’x3′ by ~ 10″ tall. It is constructed with 3- 4×4’s 1 sheet of plywood & 8 – 2×4’s. I go through the process of building the base, walls & show each step along the way.

At the end I finished with putting a drain hole in one end of the bed which will have the bell siphon.

This build took about 2 hours, getting interrupted of course, next step is to put in the pond liner, cut out the spot for the drain & attach all of the fittings.
