I hate jiffy pellets.
I was using them successfully for a while but then I ran out and just put some normal soil in nursery 6-packs...
Whe I was killing the males, I realized that the root growth in the jiffy pellets was like 1/3 the mass of the others, and when I peeled off the mesh that the roots are supposed to be able to grow through, many of the roots had just circled around inside like potbound.
Plus the pH is all wrong.
Yeah, you CAN do it... but SHOULD you?
NOPE!
I made a thread with pics somewhere... I think it's called why I won't ever use peat pellets again.
