Hello LisaDouglas,

I actually use a 40% nutrient solution, due to using aero/fog. With fog it is very easy to over do nutrients since they are directly available to the roots without any buffer from a grow medium. Pond foggers crude up, but I've had no problems with the FrapaPlas fogger. Partly due to the Frapa's design, it has a much larger ultrasonic device, but also due to running RO water during the dark period. I have a built in "cleaning" cycle.

I've used the TI's for awhile doing container grows with Pro-Mix, and like most LED grow lights they do not dry out the soil as fast as a HID would. LED's automatically have less nutrient use because of this, so I ususally use a nutes first then water once, rather then the usual feeding I use for HPS which is nutes then water, water.

Hope that makes sence.
