- How much money is required to start working on 2000sq. m. land ?
First you would need to decide what kind of setup you need ? High cost green house or low cost wooden structure or open shade net system. Then u need to decide on what hydroponic method you going to use? Grow bed? NFT?
- What are the best crops to work upon.?
I would suggest you to go for variety which can be sold for hyper markets(Lettuce,Cherry tomato,capsicum)
- What kind of return can be expected from this farming activity ?
Depends on how you want to market your products.
-
Can two crops cycle be grown in a year ?
Again depends on crop choice, Lettuce is a 45 day crop in Hydroponics from Seed. and capsicum u can manage 2 crop a year. -
What are the major concerns of hydroponics.?
First is self knowledge , using right nutrients at right time of growth, maintaining the irrigation system ,controlling PH and EC.
I would suggest you to first start in 200 sqr mt and then expand once you are comfortable with basics. Would not suggest to take direct help from any consultants and start commercial hydroponic farming as not many available in India with real commercial profitable hydroponic exp.
If u need any help on nutrients or any setup idea message me i can provide u with details, I am not available for sale, so Its only a friendly gesture .
