i already have 4x8 tray for ebb n flow
cant gett passed the water thing
seems like 100+ gallons in ebb n flow vs 55 gallons for 40 large plants , wouldnt the ebb n flow require less res changes since wter volume is so high
if the 55 gln res needed changing 1x per week the 115gln res should last atleast 2 weeks b4 change is needed?
im not saying this as a statement but more as a question
i realize ebb n flow requires more water primarily cuz it takes so much to fill the tray to proper level - but wouldnt the excess water last longer also
i guess im questioning the need to change res 1x per week
if the ebb n flow only needed to be changed every 2 weeks and the ebb n grow 1x per week min. then you would realy use equal amount of water in the end but less work on the ebb n flow
i suppose it would cost more to chill and require bigger air pump for bigger res
im just thinking out loud - quick smack me b4 i get lost in my thoughts
