Chinese Cabbage

• Light-6-7 Hrs. Daily
• Solution pH: 6.0 to 7.0
• PPM – 1700-2000

Bok Choy, Bok Choi, Pak Choy, Pak choi. Oh boy what a Joy Chinese Cabbage to grow and enjoy. Bok Choy, like many Brassicas can be grown hydroponically very successfully. It is a rapidly maturing crop that can be harvested roughly 30 days from germination. If executed correctly you can actually get 3 harvests from one set of bok choy roots.

There are a number of Bok Choy varietes. Green stemmed, red leaf variations, as well as many that have the familiar white stem.

Quick Reference

pH range 6.0-7.0 for optimal results

EC – 2.5-3.0

PPM -1700-2000

Temperatures 50 F – 70 degress F Maximum

High Temperatures can destroy the crop

Aeration of Solution and Good air flow essential

6-7 hours of light daily

Temperature

Grown in soil Bok choy fares well under cool conditions, temperatures of 50 to 70 degrees Farenheit but survives in lower temperatures. High temperatures have been known to cause bok choy to prematurely bolt to seed . Once it bolts to seed the leaves are very low quality and in many cases fit only for the compost heap.

The same requirements apply to hydroponically grown bok choy. The difference relative to temperature in hydroponically grown bok choy is the water temperatures which will also affect the amount of oxygen the water is capable of retaining. Higher reservoir temperatures will impede oxygenation.

It is advisable that you keep the solution slightly lower than the air temperature. Where the air temps can be held at 50-70 F , the water temperature should not exceed 65 F at most. See: Hydroponic Temperature. from the drop down menu on the upper left of this page..

Nutrient pH

pH levels of your nutrient solution should be 6.0-7.0 – the optimal ideal number is right in the middle 6.3-6.5 but maintaining an exact number is near to impossible as the pH is guaranteed to float around somewhat in any hydroponic solution. A pH below 5 or above 7 will lead to nutrient uptake and deficiency issues.

Water / Solution

Use straight water [pH balanced is preferable] for germination and the first few days following sprouting. Avoid Hard Water – See: Hydroponic Water Quality. By the 3rd or 4th day following the plants sprouting, use only a half-strength nutrient solution for about a week before graduating to full strength solution. It is a good idea to be a tad cynical and keep in mind that nutrient manufacturers are in business to sell a product and as a rule of thumb will usually recommend more nutrient than you actually need.

Flushing your solution periodically is necessary to prevent plant damage via Salt Build Up and other issues.

How to Grow Better Seedlings:

After selecting the best rhizome. Next, place them aside for several days to enable the split surface region to recover and grow a callus.

Ginger grows gradually, particularly outside. If you are a complete beginner to ginger farming, we will suggest you be patient. However, the sprout might arise within several days if you’re fortunate.

Continue to water for at least a two weeks. Keep hoping…

Do not place the bed under direct sun. A movable tray bed is recommended. In this stage, it needs 3-4 hour of sunlight in the morning and evening. Naturally, one acre of land needs 600 – 800 kg of seed-ginger to sow.
