Bottle of Water & AG6 Pod Grow

Peat's picture

Otherwise known as the "Coca Cola Deep Water Culture Bottle Grow".

Just for a bit of fun...

Cut the top off a couple of plastic coke bottles, AG6 pod placed inside, filled with pH adjusted rockwool. Planted some mixed lettuce/brassica type seeds in one and the AeroGarden International Basil in the other.

No nutrients used as the bottle is clear (usual algae buildup), just plain water - pH adjusted to 6.0

I'll pop this under the AeroGarden lights and see how it goes.

There's a new product concept

There's a new product concept - metal planting containers with alloys specially selected for a well-balanced mineral supplement.

Poor lettuce... That shiny

Poor lettuce...

That shiny new tin has decided to react with the nutes, lovely rust all inside it - gave the lettuce an iron sort of taste.  Moral of the story, plant in plastic, glass or something that won't rust!

That should really take

That should really take off!

Compared to lettuce grown in soil, the bottle growth rate wasn't terrible.

Week 6 (nearly) Well, I knew

Week 6 (nearly)

Well, I knew the growth would be poor - but not this poor... It will be sometime before I can eat this!

Week 6

OK, so I might as well do a proper Deep Water Culture (DWC) grow and get this plant as it should be. I covered a 1 litre container in silver foil, cut a hole for the AG6 pod in the top, airline put inside and GH nutrients (EC 1.5, pH 6.0) added - full vegetative growth stage. Water topped up to about 3/4 of the container, need to leave some space for the air roots.

I probably do it once every

I probably do it once every couple of days but probably not enough...  The Wax Gourd is bad for germination rate.  My Mom planted a dozen in soil and only 2 germinated after 24 days and I only have 2 in the Pod.  Coreopsis is suppose to be around 21 days for germniation..  Maybe I will take some solution from the AG, dilute it and add to / replace in the vitamin water bottles.

Or just lift it out once or

Or just lift it out once or twice a day to provide O2 to the roots. That's in essence what my greens outriders are.

The peroxide is good to have

The peroxide is good to have around, it will probably do the plant some good. After all, the water is stagnant and I'm not the quickest to change it very often!

For really good growth, you need a small airline going in, blackened bottles and some nutrients - there you have it, a very cheap AeroGarden; minus the light! It does essentially the same thing and is adequate for small grows.

For the Coreopsis and Wax

For the Coreopsis and Wax Gourds, both have not germinated after 3 weeks (2 of which in AGs) but both are slower germinators.  I forgot to adjust the water and rockwool to 6.0 but did it a week later when I did the 2nd set of rock wool for tomatoes and lettuce.    Have not changed the water yet so should I guess.

Both the Grand Rapid Lettuce and Chadwick Cherry Tomatoes were germinated in the Vitamin water bottles and swapped into AGs at 1 week or 9 days.  They are a bit slower but seems okay.  Did remember to adjust pH of rockwool and water for this.

I guess i should pick up some pharmacy hydrogen peroxide..

I made sure my water was

I made sure my water was adjusted to pH 6.0, I did not put straight tap water into it. The light they have received is overspill from my 125watt grow bulb - that will probably make a difference.

About 4 days ago, I changed the water and added some hydrogen peroxide to aerate the water. You could see the stuff taking effect, the rockwool was covered will lots of little oxygen giving bubbles.

Other than that, pretty standard.

Peat, I have some Grand Rapid

Peat,

I have some Grand Rapid Lettuce that I sprouted in rockwool within Vitamin water bottle that I swapped into my SS6 at a week old.  It is slower than yours and also my Musculun and Arugula at 3 weeks looked a bit behind he salad green or your water culture.. humm, what is up?
