im sure everyones method varies but it doesnt make much sense to me flushing over a long period of time in smaller portions , the whole put is to use a high volume of water to FLUSH out the excess salts that build up over time from nutes , so in my humble opinion it wouldnt be very beneficial to use small quantities of water over time vs when i flush i use 3x as much water as the size of the pot ALL IN ONE SESSION just think of it as giving ur soil a bath ..... u wouldnt wash your arms then hop out the shower wait a day then wash ur legs an so on an so on ..... hope that helps -Take Care an Happy Growing -
