hi ron,
can you please tell me the difference of ammonium nitrogen and nitrate nitrogen as far as its relationship to plant growth ? secondly, my lettuce ... i place them under 75% shade cloth, temperature is also hot ... around 110F at mid-day .... result is gap between nodes are really abnormal. i am using heat resistant and bolt resistant cultivar for my lettuce, do you suppose the shade cloth is the main problem ? regards, sixto |

Nothing in my hydro books about ether.
I can't imagine growing anything at 110 degrees especially lettuce with or without shade cloth. |
