I'll give you one to consider that I didn't when I first did an 18 gallon tote grow: changing nutes every week. A gallon of water weighs about 8lbs.
Just something to keep in mind.![]()
Thanks. I have a system planned for it to make life easier when it comes to that point. Using an electric siphon pump, siphon out the res water to a waste area (bathtub, buckets, another tote, outside, etc) and then have a 2nd 18 gallon tote containing fresh, ph'd water and nutes ready to siphon back into the res. Quick and easy. Plants would probably get 10-15 minutes of air.
