Hi
After following sthh and fellow gardeners on their experience with hydroponics, I have started a mini hydroponics project with my son. As I have not purchased the hydroponics nutrient solution yet, these plants were grown using the nutrient solution for indoor plants sold by World Farm and a pinch of Epson salt. I will be changing them with the hydroponics nutrient solution this weekend and hope to see better growth. Surprisingly, the hydroponics nutrient solution is cheaper!

I have tried aquatic sponge and cotton wool as grow media. Both works but the aquatic sponge is easier to handle, gentler on the roots and can wick water better.

Enclosed some pictures uploaded on photobucket.

Good growing. I see roots coming out already, and the plants should all grow rapidly after that.

Growing collection - Malabar spinach, water spinach, amaranth, tomato and chilli. Unfortunately, the watercress rotted after 1 week and I wonder why. I have cut the stem with leaves at about 7 cm in length and rooted it in clay balls placed in a container filled with water and aerated with pump and air stone. There is little or no root growth.

The water spinach is ready for my salad after 24 days. It has grown faster and looks better than those grown in soil. I am glad that I do not have to fight with snails and slugs for the vegetable. Time for the taste test in a day or two!

The Malabar spinach is growing very fast in soil once it is established. It has grown to 2 feet tall after 1 month. I have to put up a trellis this evening after a stem drooped after a heavy downpour. I have pinched off 4 juicy leaves for my salad....Yummy!

Are one of these plants kang Kong? if so these plants have a huge root system and drink up lots of water , check in the morning water is full, check in the evening empty.

I am happy to see in Singapore with such limited space that you have set up your hydroponic garden very well.
If you can get larger containers this will allow plants to grow larger and like the Kang Kong the water and nutrients will last longer. Keep the photos coming I enjoy seeing your success.

I just raced outside and took a photo of what I meant about Kang Kong , I am growing these in DWC ( Deep Water Culture)

Can cut the malabar spinach and root in water?

Robert, your kangkong very lush, how many you squeeze in one net pot? Do you harvest them by cutting and let it regrow?

Hi Jesse I put one plant per net pot , sometimes I let it grow but after a while it slows down , so then I grow from cuttings but after a while they do not grow very well so I plant seeds , these plants were grown from seeds but after harvesting I will grow from cuttings etc.
So in other words I grow from seeds, I also grow from cuttings, and I also let the Kang Kong have another burst of growing so all variations are acceptable.
In the meantime I have planted another 6 seedlings so I will always have Kang Kong.

When I was in Penang a couple of weeks ago I went to a Thai restaurant and had fried crisp Kang Kong which is so different to stir fry. (Ps my wife is Chinese from Penang)

Whoops I forgot to answer one of your questions , yes cuttings can be rooted by putting in a glass of water, so it really takes off growing really well when put into hydroponics, I tried putting into soil and it died. Roots sprouted in water and then into hydroponics is the way to go.
Good luck I am really happy for your energy and perseverance , as that is what makes gardening in whatever form so enjoyable, we all have failures and yes we also have success, however if we use the success principles and pass it onto others then we do not have to re- invent the wheel as the old saying goes.

Hi Robert, ya i was pondering how many times the kang kong can really last from the harvesting. I only cut the top part, leaving the roots intact to regrow again. I can see that you have constant supply of kang kong. I will try to grow the malabar spinach in water and see. Thanks!

Hope that Grace dun mind me interrupting this thread. :)/>

Hi Robert
Wow! Your kangkong has strong and lushroots. I will try growing one per pot instead of crowding them. Currently, I only need to top up once a week. Thanks for the tip.

hi Jesse
I welcome discussion on the thread and learning from one another.. I have experimented rooting the malabar in soil and water, both work for me. In this one time experiment, I have better results for rooting the bottom part of the stem directly in soil. Also managed to root top 3rd and middle part of the cutting in water.

I must now apologise I Seem to be in everybodys thread and crossing back and forth into different subjects. I have been playing around with hydroponics for over 40 years and it has only been in the last 1 year that I have been getting great results, up till now I was having 50/50 success rates with all plants that I grew.
My current results are outstanding only because for all these years it was trial and error with some plants growing extremely well and others were a disaster.
I understand that In Singapore space is at a premium and only small areas are available to grow those plants that you love to see grow and perhaps eat knowing that it was because of all your efforts.
I do not want to lead your thoughts to anything expensive or beyond your comprehension , but when I understood that plants have different requirements eg sun, PH and nutrient strengths only then have I had extremely good 100% results.
I understand that in Singapore you have a hydroponic store called Eco City who do have all the things that I have explained above. Hydroponics is fun and should always remain that way and I only mention Eco City if you wanted to go the next level.

Some plants are acid loving and companion plants can be grown together, other plants like Bok Choy are nuetral PH eg 7.0 and have a weak nutrient level strength, whereas Kai Lan have a ph level at about 6.5 and a higher nutrient strength. Egg plant is growing in the same tub as the Kai Lan as they are compatible etc etc
I understand this talk may be way over your heads and if it is I apologise once more, however if I can simplify your approach to different plants then you will be pleasantly surprised.

If I can help with any information on any plants I would not mind assisting where I can help and no question will be taken as trivial and I would give the best advice that I can.

Lesson learnt : The pot is overcrowded. Should have planted only one amaranth in the container instead of 4. Two plants have grown to the same size as those planted in soil while another 2 are lagging far behind. Observed that the red markings on my amaranth grown in the nutrient solution is more prominent than those grown in soil.

Bought some watercress and tried to root the cuttings again. After 1 day, they looked listless and I planted them in soil immediately. The watercress seemed to have adjusted to the soil and put out new shoots after 3 days. Did anyone have success growing watercress by hydroponics?

Placed a "rain cover" on the Malabar spinach and put it out in the open. The plant survived several downpours and I did not notice any change in the nutrient solution level. This experiment opened up greater possibilities of where I can place more plants.

I am curious to see how well an Africa leave plant which can grow into a tree do in hydroponics. Experimenting growing it via kratky method for simplicity although it would do better if grown in the ground. Surprised to see it still going strong at 66 days and putting out big leaves and a lot of roots. Going to top the plant to make it bushier, change into a larger reservoir and watch its growth.

Experimented growing Malabar spinach for the first time in Oct using various parts of the plant. A total of 11 cuttings were planted in soil and hydroponics. The Malabar spinach in nutrient solution grows pretty fast and reaches >1.5m at 68 days, comparable if not better than those grown in soil. Those grown from shoots grows slightly slower and did not put out side shoots compared those taken from lower stem cuttings. Noticed colour difference between those grown in partial shade and full sun. Have been picking leaves from the plants for weekly juicing/salad. The leaves are softer and tastier than those in the markets. Hesitating whether to cut the plants down for a meal and encourage bushier growth or leave them on to flower. I was told that the flowers are pretty. I should have enough for a meal.

These are grown from the shoots and the growth is slightly slower than those grown from bigger cuttings.

Well done, as they say you can grow anything in hydroponics even a tree if you can supply enough nutrients to to plant.
When you think of soil gardening whether in the garden or a plant pot it uses a similar principle applies eventually all the nutrients are used up and we add more fertiliser.
My ignorance what is an African leaf plant.
With many of my plants including tomatoes I have to have strings or rope to allow these plants to grow taller as they will fall over with their weight.
Ground planting is similar with stakes.

Wow, your Africa leave plant and malabar spinach are growing very big, and looks delicious. I must go find some malabar spinach soon. I read somewhere that once malabar spinach blossom, their leaves turns bitter, and to prevent blossom is by providing lots of water. I think I only ate malabar spinach once, I asked the market person what plant it was, they just say it is good for smokers.
