Passive Kits And Systems
Passive kits and systems consist of hand or capillary-watering (also known as wick systems).
Hand-watering is exactly what it says – watering by hand. This method depends on how much effort the grower is willing to put in, but does not really offer much more than traditional fertilisation techniques.
Whilst capillary-watering can be achieved through a range of techniques such as using a valve from a reservoir, having pots that sit on a regularly watered capillary matting, sitting pots in a shallow reservoir, where the capillary action draws the solution up the media; or placing individual pots in trays or saucers that the solution is put into.
An example of this type of simple system is the AutoPot Watering Feeding Systems.
