In the wick system the roots are moistened by the
nutrient solution passing up a
wick made from glass wool, rayon, polyester or by using a lamp wick.Stand
a pot, supported above the nutrient solution, in a tray.
Soak the wick thoroughly before passing it through the drainage
hole into the nutrient solution, leaving 10cm of wick n the pot.
Unravel the upper end of the wick to give better distribution of the nutrient
solution throughout the medium.
The growing medium must also be thoroughly soaked to enable the wick to take up
the nutrient solution.
The tray will require topping up with fresh nutrient solution as it is used.
