We also set up an experiment on hydroponics . We started by testing the water. It was quite alkaline so we corrected the PH of the water by adding lemon juice. Then we added the correct amount of nutrients to the water After that we soaked some rockwool plugs overnight in the nutrients infused water. We then placed then into the plug trays. Next we sowed some cress and lettuce seeds into the rockwool plugs.  |
