Hi FTP817- I use a T5 unit. It has 8 each 4 foot tubes. I use it for the veg
stage and it is VERY GOOD. This would be good for your mothers but too strong for the babies. For clones I use 4 of the single
tube (4 foot) units mounted on a board that I can move up and down. Four tubes over the clones does well for me. Rooting over 95% in 10-15 days.
P.S. Did you know you don't have to have mothers?(this statement may freak someone out...)
