Chris,

I don't grow dens, so cannot make a recommendation either way on them, but
all of the others will do fine in S/H culture.

If the plants need repotting, move them into whatever size is appropriate
for the plant. The change in culture method does not change that.

Use the coarse grade of medium.

If you buy the pots from me, "The Store" tells you the capacity of each
size.

I'm thinking after my plants finish blossoming out I'll go semi-hydro. I
have 3 den. 2 onc. 2 phal. 1 miltonia all in 4 in pots. Are all of these
ok
for S/H? What size pots should I buy? Should they only be plastic? And
what amount of clay pellets should I buy to pot them in, and at what
grade?
Also where should I buy (I prefer online if the price is right).

Thanks
Chris
