As you may already know, aquaponics works on the symbiotic relationship that is established naturally between the plants and aquatic animals. A mini ecosystem is created and the re-cycling of wastes as fertilizers for the plants occurs. In essence it really combines hydroponics technology with agriculture. The question lies, what’s the best aquaponics plants for the system?

Growbeds are used to grow plants in aquaponics and instead of soil, river rocks and clay pebbles are popularly used as the growing media. Here, water is continuously run through the system to provide the plants with a nutrient rich environment to thrive on.

So What Plants Do Well With Aquaponics?

There are over three hundred different types of plant varieties that have been tested to grow well with aquaponics. The variety that does not seem to do so well with this system is root vegetables. These are plants that are produced underground, like potatoes, onions and the like.

What Are White-flies?

Their appearance is angelic for sure, with their whitish bodies and wings but don’t let that disguise fool you. White-flies are very closely related to aphids. They can be as small as 2mm long, soft bodied, winged insects and are found in almost all the regions.

Being tiny in size, they are often camouflaged. They also love to hide in clusters on the undersides of leaves which make them even more difficult to be detected and they multiply really fast. White-flies are active during the day and can live through winters as well.

Aquaponics SeedlingsToday, I would like to touch on how you can transfer your aquaponics seedlings to the grow bed. Now, you could be transferring seedlings from a nursery that you may use or from your grow bed itself. It all depends of course on where you sow your seeds. For me, I sow them directly to the growbed and the technique on transferring the seedling is the same either way.

To begin with your seedlings need to be of at least three to four inches in length. That’s my recommendation. This is mainly because, if you do it any sooner the seedlings roots break off easily and you may risk the possibility of damaging them for good. So, do bear that in mind. If you are using hydroton as your media, you can actually let them grow bigger before transferring you seedlings. Hydroton is a joy to work with and it’s easy to transfer your seedlings or plants in them.

I’ve just harvested my “Bok Choy” from my flood and drain hydroton media bed system about two weeks ago using the cut-and-come-again technique. It didn’t work, and for a good reason. Explore further to find out why.

Cut and Come Again

Bak Choys never seem to grow big with aquaponics, well at least it’s true with my set-up, but they taste really delicious though. I tried the cut and come again technique for the harvest this time around but it didn’t work. This is what happened…

I was doubtful when I tried it, mainly because I didn’t think the bok choy were big enough to perform one. But the curiosity got the better side of me and I had to go with it!

A cut-and-come-again harvesting technique leaves your plants growing again and again without having to up-root them. Now, for bak choi the proper way of doing this is to cut the leaves above the growing point. This way, the plant is able to regrow it’s leaves to be harvested again.

Here’s a video showing the proper cut-and-come-again technique on bak choy plant:

Well, due to the fact that my aquaponics bak choy were small in size and they did not grow the way they do on soil, I made the cut here, please see picture below, just to see if it works:

And after two weeks this is what happened:

Cut and come again technique

The bok choy stems dried and the leaves never grew back up again…Look at the positive side, I have successfully proved that cut-and-come-again technique, cannot be done this way :).

I hope you have gained some extra knowledge and understanding about cut-and-come-again harvesting. What works and what doesn’t. Try out new things, be adventures about it. And most importantly have fun with it.
