Hey all!
I'm looking to flush my rockwool cubes of salt build up once a week after changing out my resevoirs. Is it better to use plain PH'd water for a weekly flush, or can i use the nutrients in the resevoir i just changed out, about 1000ppm right now?
Thanks a ton! What's your method of flushing the rockwool cubes. Do you flush water over the tops of cubes or just flood your trays with ph'd water and solution? And for how long?
