I have a 5x5 Tent where I have mothers, a Homemade 54 gallon Roughneck Hi-Top Aero cloner, and my crop waiting for the flower tent. I have plenty of space and enjoy working with mothers Bonsai Style. Its fun for me to keep mothers and trim roots and take clones.
I have a few crosses of my own and would like to make a few more so mothers are practical. I like to keep mothers as a fail safe if for some reason all the clones die from a pump/power failure or something weird.
To each there own, that is the beauty of this hobby, So many ways of coming to the same end result its all about finding what is fun for you.
