bman, actually nutrient uptake of NPK is highest at 20 deg C. Plant growth is highest when the solution temperature is between 25 and 30 deg C. 25 deg Celsius seems to be the happy medium between the two. As the temperature of the solution drops below 68 deg F. Phosphorous uptake drops at a higher rate than does Nitrogen and Potassium. Have you considered putting mycorrhizae in your solution? This is just one of several formulations on the market today and this one is from fungi.com. And one application should be all that is needed to innoculate the roots. Ami
