Draining My Reservoir

Hello, all. I'm a couple of weeks into my Master Kush grow from seed. Right now my plants are in root cubes. I expect it will be at least a few more days until they're ready for transplant. I'll be putting them in 2gal pots, part of the Ebb & Gro system.

I'll be draining 30 gallons every two weeks. I have no idea where I should get rid of the water. Is it ok to drain it into my yard? Can I pump it into a bathtub drain? Please help.

You can spray it on your grass or plants now and then, yes it can go down the drain, nutes are no more hazardess than the chemicals we wash with.

I fill up old gallon milk containers with the old nutrient and water my indoor plants with it.
If there's alot, I give some of the containers to friends.

Great to know. Thanks for the replies, guys. I'll try and post some pictures after the transplant.

I use it in my outside real garden the tomatoes love it.

use the pump to pump it out into other containers.. then rinse well
