New Grow, Old Favs!

Getting a little stronger each day. Feel real bad about butchering them up. Hopefully it will be for the best. Have another "split" grow. That's what I call it. Going out skiing in a few weeks. Have to make some changes to the garden for it to survive a week alone. I bought these 6.5 gallon low plastic bowls. Planning on filling them up with nutes before I depart. Hoping it will make it. Has anyone done something like this? If you had hydro, that would be easier as you already have the reservoir. Open to any other suggestions from the collective here.
