Thanks R1Tony !Sweet flo. Couple questions:
How often do you completely change your water out? How do you do that? I ask because I just completely changed my 9 gallon tub today since my tap water was 780ppm (out of faucet) on my newly bought TDS meter. Ran out to get RO water (.01 ppm in 5 gallon bucket) and filled it up with 450ppm (FF Big Grow mild dose for seedlings) and ph at 5.8. 9 gallons was heavy as hell to take to my utility sink and completely change it out. Per my other thread my seedlings were curling and not growing as expected. I was using a drop ph meter and no TDS meter, so my water I think was almost toxic to the little guys(girls).
To be honest, I have read, seen and heard all the THEORIES on rez changes.
As I was in the beginning of my grow, somethingS occured to me that are completly sensible:
1) Keep my rez clean as possible and I won't have problems with PH/PPM stability, unless caused by the plant eating.
2) Keep my temps STABLE and I won't have any problems with PH/PPM stability, unless caused by the plant eating.
3) If I replace 1gal of water into the rez daily plus nutes, then after 10 days I have completly replaced ALL the previous 10 gallons of water/nutes.
4) Replace/change nute solution when I switch to bloom only nutes.
I was using a Drill Pump ($7) until Lowes started selling Bucket Max.
Bucket Max is a 6.5 amp Wet/Dry vacuum that snaps onto any standard 5gal bucket for $19.95 !!! Buckets are $3 at Lowes.
Lift my cooler lids, stick the hose in and pump away.
Twice per cooler.
