About Antonius Lecuona

I studied agriculture at the University of Stellenbosch in South Africa in 1984 and completing my M.Sc Agric. in 1998. . My love for "Controlled Environmental Agriculture" (CEA), started in my third year when I was exposed to the Welgevallen Research Station. There Prof. P.C.Maree showed us what hydroponics consisted of. It was awesome. There were no large tractors involved, no dusty fields, no uncontrollable storms to destroy your crop (well that is what I thought). Since then I put hydroponics to much better use, not just farming. We solved pollution problems by cleaning mines effluent with hydroponics and aquaculture. They were used to remove toxic metals to produce clean water (which we sold and make more money of than the produce). What I learned from 1987 I tried to compile in this website and I hope it is from some value to the serious commercial farmer that wants to take the journey into Commercial Hydroponic Farming.

What is nutrient conditioning?

2019-04-23T06:26:17+02:00By |Seedlings|

Nutrient conditioning is the process of managing the nutrient content of seedlings in the nursery for optimal growth when they are transplanted. This sounds easy, but good growers achieve higher yields with the same variety because they understand how to manage it correctly. We all know that plants need adequate [...]

The effect of light and temperature in plant growth (Advanced reading)

2014-10-31T17:02:02+02:00By |Cultivation|

Light and temperature are two crucial factors in greenhouse hydroponics. Plants use a very small range (only about 5% of visible light) in the total spectrum that is found in the atmosphere. The rest of the incoming radiation is not used in photosynthesis or for any chemical growth process. The [...]

Increase container size for higher yields early in the season

2014-10-31T17:03:12+02:00By |Seedlings|

This is all about getting higher yields early in the season when you can get higher prices. It's about going into the market with a bigger bang and reaping those higher prices. It does not apply during the growing season, because there are other economic factors involved. Remember, bigger plugs [...]

Why do Green Pepper grow so slowly

Actually, green peppers grow just as fast, but the perceived vegetative growth is much slower. Green peppers [...]

Are organically grown vegetables better – The real truth behind it all

2014-10-31T17:10:13+02:00By |General|

There is a hype about organically grown vegetables or any other foodstuff for that matter. Here is the irony in it all, the people that can afford organically grown food, usually don't need more nutrient, or better nutrients in their diet because they are already eating well. So why on [...]

What is the nutritional value of vegetables

2019-04-11T11:16:21+02:00By |General|

The nutritional value of vegetables is easily answered by the popular media, just slam a couple of very average numbers next to a couple of crops and the consumer/reader is satisfied. It is actually not so easy to answer in a single digit. Everyone wants a single value digit because [...]
