About 10 min to fill one tank completely
| Step | Image |
| Get a portable Dosatron from another house and fertilizer concentrate. The Dosatron dilutes the concentrate with the correct amount of water. The concentrate should never be used to water plants directly. The fertilizer generally used is 250 ppm Nutriculture. Greenhouse staff can mix concentrate if requested. |  |
Take the Dosatron to 2E5. Connect the hose on the Dosatron and the hose in 2E5 as shown at right. |
 |
| Release the hoses by pushing the metal ring on the connection away from the hose you wish to disconnect. The metal ring must also be pushed in when reinserting the hose. |  |
|
Turn water on and wait for water coming out of the hose to become light blue from the fertilizer (you can see this in the water on the concrete). Fill tanks with water containing fertilizer.

|
| Return hoses to the original setup and the Dosatron to its previous location. |
