Some Flourish One Survived Others Die

squash-cayenneSadly, the squash plants on the right had mostly died off except one that is still surviving. The leaves were never really showing the potential, but I thought by transplanting into the aquaponic boxes they might grow better. Instead they died. I pulled the dead plants up and observed that the roots had not grown and the root system was not large enough to get enough nutrient from the environment. Well, one lesson learned – check the roots before any more transplant in future.

On the other hand the Koi fish have taken to the new environment with delight. Perhaps it’s the number of times we, me my partner and my son, fed them in the last two weeks – over feeding – they have obvious growth in size since their arrival. They have taken to understand that if sight of human appears in the surface they should swim to the surface to wait for abundant food. Usually their feeding habit is that they will snatch 3-4 large chunk of feed and then swim below to digest before coming back to the surface to finish off the rest of the floating feed.

The water in the system is all clear now. The muddy silt has sunk to the bottom of the sump tank. The PH has decreased to about 7.35 (from 7.8) as it supposed to. The ammonia level also reduced from the initial introduction of the fish of 1 ppm back down to 0.25 ppm.     I have replaced the dead squash plants with more cayenne and aubergine. so I am seeing a lot of pepper in my future.

Aquaponics Systems in Hong Kong

It took me the whole of last week but I have finally built a prototype of aquaponics system on my balcony. I also spent about an hour and a half yesterday to shop for my fish. After walking around for more than an hour I’ve decided the best fish to add for my system is six six-month old Koi fish. They are colourful, resilient and easy to take care of.

As Sylvia Bernstein in her Aquaponic Gardening book said, the fish is the power and the fun of the system. My partner and I spent hours looking at the auto syphon flushing water from the boxes and how happy the fish come up to greet us when we feed them in the morning afternoon and evening. They are like our children now, that we will go out on the balcony to check on first thing in the morning and the last thing to do before going to bed.

Just look at them,

Transplanted them two days ago and new leaves are appearing already.

The system is assembled on the south-facing balcony. It has sun light for the whole day and being on a raised level it is the perfect location for my grow boxes.

The contraption is actually a water circulating system for the grow box and the fish tank. Using a close loop ensures the water pressure is evenly distributed to both the fish tank and the grow boxes.

The sprinkler is for aeration of the water in the fish tank to enhance oxygen level in the water for the fish.

The grow boxes are assemble and ready to be filled.

It’s working!

The Summer of Plenty

The warm weather is finally here to stay, perhaps a bit of understatement at that, and the temperature is well up there near the top of twenties Celsius. The entire garden is rejoicing with tremendous growth. In one week the grape-vine has grown 12 inches; the bitter gourd which had sprouted but with marginal growth is now in full bloom; once I added liquid nutrient the lettuces in the hydroponic boxes come alive.

The strawberry plants I bought in the new year have been bearing fruits, and they are sending little suckers out to expand its territory. I am exploring vertical growing technique by building a two level boxes to provide landing pad for the extensions. Once the new suckers take root then I can cut of the stem link and grow that as a new plant.

Water Water Cried the Lettuce

Remember the last complain about high humidity and fog? They are no more. In the past week, it has been 70% and temperature of 18-22C. Perfect weather for growing, and no doubt the lettuces and beans etc are all enjoying it. Instead of taking up about a liter of water per week the plants have been demanding about 2 liter of water every other day for a tray of twenty pots (lettuces).

I am happy that they are happy! I am also expending my plantings with eggplant and fire bean haricot transplanted. If the weather holds up I expect to be harvesting the haricot beans in 2-3 weeks time. Keep the water coming says the bean.

Sunshine, Oh So Brief!

I have not blogged for a couple of weeks, because, it was such horrible weather – rainy patches and cloudy sky for almost everyday – since my last post. Was it that the weather that made the plants so depressed or the people so unenergetic? Anyway, yesterday was full of sunshine and warmth, the whole day was sunny with temperature in mid-twenties and humidity 70%, perfect weather for growing, which is when Fiona decreed the spring has finally transfer power to summer.

Well not so quickly, today it’s turned damp and foggy again and the weather forecast is for the week to have more rain patches and humidity of 90%-100%. How can we have 100% humidity, I ask myself? No wonder many of the flowers died, including the borage that was blooming with purple flowers before the dampness set in. Now I am pondering the same fate for the next batch of squash flowers.

The lettuces are doing fine despite all of this. We have harvested one full tray of endive leaves and made a beautiful salad tossed with red leaves lettuce, spring onion, tarragon and sage. A little balsamic vinegar and olive oil together with Canadian Angus beef and sausage, it’s a typical farmer’s dinner.

Dampness or not more seedlings are sprouting – garden lettuce, Taiwanese Kuai Cai, apple cucumber, chili and others. Fennel is growing into a young adult and rosemary continues to spread her wings. The fig trees are sending out new leaves so that in the summer it can dance with the sunshine. miraculously the deemed-to-be-dead basil seed bed came back to live with more first leaves emerging. So we just have to brace of the last days of the spring-mother-nature and cheers the summer to arrive.

Salad Unlimited

This site was launched this morning, and I have been receiving some very good comments already. Thank you so much to all of you that have taken the time to comment to make my blog better.

My growing have been going on for quite a while now and although my squash plants had never gotten any pollination because of the weather, one vegetable I have been able to enjoy (fresh from the garden) is my endive and red lettuce leaves.

The other night, we had a dinner of BBQ steak bought from the market but we have also been able to sample the lettuce grown hydrologically on my balcony. Of course the plants were not mature enough to be harvested as a whole head of lettuce, but it didn’t stop us from cutting one leave from each plant to make a nice big bowl of salad. Toss them with balsamic vinegar and our own basil olive oil, it’s a dynamic green salad to go with grilled steaks.

Think about this, the lettuce will continue to grow but we can just pick a leaf off everyday to make our salad. My supply will definitely be limitless.

By the way the taste was superb (really blowing my own trumpets here) and what can be crisper and fresher than leaves picked from the plant and served on the plate in a matter of minutes?
