Hi folks.

Emersed growing is the big thing in commersial growing, but when I tryed this in small scale it always ends in failure. Either bad growth, dry out, molds, pests, and at the end lack of love from me with total failiure as an result.

This time i will try out the hydroponics style, and I appreciate if you would like to give me feedback on this trial version of emersed growing project.

Hope you like it and get inspired, and for you with experience, please give me imputs to aprove the project so i can hav an success this time.

Cheers H

OK, so this is how i got started in 27 september 2019

Two tubs, each 50*30cm aprox.
Lighting: 2*39watts T5, one to the red spectra and the other more to the cold side.
Air pump with two airstones to create watermovment and oxygen to the roots.
Water filled up to an point of perhaps 10cm in the tank. An simple grid that will keep the plants in both water an air.
Ferts, PMDD, but not started yet, due to levels not set
At his point I only had HC Cuba plants, in emersed condition so they would probably not dry out the first days.

They have high humidity in their greenhouses ( 80 procent or so, and for some almost 100). that's key.
Thanks Edvet, Yes I notice they need very high humidity in the startup phase. My experience when placing plastic film over the tank is that plants get sick if not ventilated enough.I hope the microclimate in the tank is high enough due to the bubbels. But 80-100 is too much for an normal house in the long run, I dont want the house to be sick.

very high humidity in the startup phase.
Have you thought about using plant propagators, the type with a plastic base and a transparent domed top. Some come with a small pump and spray nozzles to produce a course mist or very fine spray. The transparent domed top usually has one or two ventilators depending on size.

You can get the type with pump and spray nozzles from hydroponic outlets. The other type can be obtained from garden centres, sometimes at reduced price due to seasonal clearances. Most garden centres are now Christmas Grottoes.

Currently have a large Anubis sitting and growing in a propagator while I make it a new home. (It out grew my tank, but the space created by its removal has been filled by other Anubis, always thought they were slow growing but show them ferts and they start to motor.)

Best wishes with your project

Thanks Oldguy, i am trying out with separate smaller buckets, but that was an clever idea, with cup cover only. It is really difficult to get the plant from aquatic to emersed right now, they just melt down. I will definetly try out theese cups if i can find any at home.

Thanks O.
Pictures will come soon.

What you are talking is riparium, growing semi emersed plants. Hydroponic refers to growing plants in soiless media relying on water for all nutrients. Technically, a EI planted tank on inert sand or gravel substrate is a hydroponic system.

I have had good success growing Staurogyne Repens in a small window cill propagator. The trick is definitely keeping humidly high, I spray them occasionally with RO water. During the hot spell humidly dropped and I lost a lot of the leaves, there's still a few crispy leave in there unfortunately.

Not so sure i know what riparium is, but this is not an tank with livestock, and no soil.

Wow! That looks really dense and healthy.

RO water you say. I am thinking of giving N-P-K with the spray water...

Only HC Cuba is thriving now, well also the basil.

But I will try to find some kind of cups to place over new aquatic plants untill they are adapted, this will keep it moist, the room is only 45-55% moist today, and the plastic film is not covering it compleatly.

I do add a small amount of macro ferts in to the water occasionally. It's had a few trims to get it nice and dense, it was getting tall at one point. I'm not actually sure what to do with it now o_O

Now the roots are visible, and the plant sends out new leafs.
Best thriving is HC Cuba i would say so far.
I am struggeeling with humidety, that is the hardest to get right. Submerged plants just die off when planted here.
Aeration in the tank do well and plants roots look healthy.
