This article is a continuation of Part I of Hydroponic Cucumber production. The response to the previous article was amazing. Questions started pouring in in huge numbers. This shows how much interest people have in commercial hydroponics. I will try to keep these articles simple for a home gardener and at the same time, sticking to methodologies followed for a commercial production.
This last part dealt with seed starting, transplanting and training. This part will deal with crop management, irrigation, fertilization and harvest.
These plants are about 40 days from the date of sowing. They are sown in black polythene bags filled…
Wow!! is really all one can say. It's hard to believe my eyes considering the strange problem I'm having. The European cucumber seeds you gave me have 100% germination and the vines grow quickly and just as quickl yield flowers and set fruit. But the cucumbers are remaining tiny and then dying without maturing. I'm spraying MaxiGrow once a week and have tried reducing the watering as well as watering every other day. But no luck. Do you know what could be going wrong?
I think I know the problem you are facing. MaxiGrow supplies only NP and K. One of the main requirement for soilless growing is calcium and these plants need 200ppm of calcium in their feed solution. The fruits will be thicker at the stem end and dry, shrunk underdeveloped at the blossom end(the end that is opposite to the end that is attached to the stem).This is the symptom for Calcium deficiency. Add calcium nitrate @ 1g/litre of water and water the plants. They will spring back to life. Hope this helps. Along with calcium, magnesium is needed too and that is not supplied by Maxigrow.
