Why you should control pH and conductivity in hydroponics

12 May 2016|Hydroponics|

Why? That is a great question, let's dig right in! When we grow plants in pots for any other similar containers, we're limiting the ability of the roots to explore the ground looking for water and nutrients. Thus, if our intent is to grow plants inside of a pot, we must provide a suitable environment and [...]

Pest Management; talking about bugs

6 Apr 2016|Hydroponics|

The indiscriminate use of pesticides is bad for the environment, bad for the final customer and bad for the farmer. They are so harmful that you should avoid them unless it is the only and last option. Moreover, it is not sustainable, because its continued use  induces mechanisms of resistance in pathogens. This means that [...]

The disease triangle, or how to grow healthy crops

28 Mar 2016|Hydroponics|

For a disease to develop, three conditions need to happen: There is a host plant susceptible to the disease. The pathogen which causes the disease is present. Environmental conditions are favorable to the development of the disease. This is called the disease triangle. We may act on all three sides of it to keep our [...]

How often and how much to water a substrate system

10 Mar 2016|Hydroponics, nanny|

This is a technical post for those who want to optimize irrigation of their hydroponic installation. We will use the concept of Readily Available Water or RAW. RAW means the volume of water that a substrate holds, that is easily taken by the plant. It depends on the substrate characteristics and the pot size: Substrate [...]

How to choose the right substrate?

3 Mar 2016|Hydroponics|

As one of my professors always said: There is no perfect substrate, but a perfect management for each substrate. Many materials can potentially be used as horticultural substrates. There are some quite exotic like rice hull, volcanic rock, coco dust, biochar… In fact the ideal substrate for you is the most accessible, cheap, that covers [...]
