Step 3 Water Supply

Water Supply

Plumbing the plastic Jerry can

Step a
Fasten the plastic Jerry can (fig. 03) up side down securely and drill the correct hole for your nutrient tube grommet (fig. 04) (4mm tube in my case) hole

>> critical note- experiment with your grommet holes before you drill your container - some have the correct size hole dimensions marked on them, other wise you might end up with a whole to big that leaks. The grommet spreads when the tubing is pushed in to it but the hole <<

Step b
Push the 4mm supply tubing about a cm in to the base so that sediments and muck dont get in the line. (fig 05)

Step c
Cut two wooden blocks to support the Jerry can high enough so that the tube exiting the base is not squashed, and can naturally curve down to the tray tube. If you don't have the room for this you can use 4mm elbows. etc.

Step d
Position the Jerry can as high as possible above where the plants are going to grow, there must be a natural fall for gravity to supply the auto valve and the plants.(fig.06)

Step e
Construct some form of box and lid cover to isolate the Jerry cans from sunlight (algae love nutrient solution also!)(fig.29) see lid back in fig.06

Step f
Place a 4mm tap in the supply tubing at a location prior to the glass house below the Jerry can.(fig.07)

Step g
Drill a 5mm hole in the glass house frame and pass nutrient supply hose through from in side the glass house ( keep the roll in tact) - connect that end to the tap - put the roll aside for now (fig.22)
