Hi!

Im doing my first grow. Aquafarm (drip feed) hydroculture with clay pebbles.
So, i read that ec should be around 0.5 (350ppm) for seedlings. My tap water is around 0.2 ec, so after i add nutes it should be 0.5? (0.2 from tap warter and 0.3 from nutes) OR do i add 0.5 from nutes to my tap water, 0.2 + 0.5 = 0.7?

So which one is the right one? 0.5 after nutes or 0.7

After the seedling phase i can just check if the ec goes up or down and see from there which is the best solution. But now, when the plant arent drinkin so much etc its impossible to do so. Help needed! sry for bad eng. hope u understood :>
 
I run the waterfarm drip feed with clay pebbles.

I had to run 100-200ppm for the first few weeks. Just remember, nutrient burn will cause a lot of problems. Avoid it at all costs!
