You don’t need THAT much pumice. If you are building your boxes correctly, there shouldn’t be that much room between the root ball and the box.
The other nice thing about pumice is that after you’ve purchased some, a lot of it can be reused for subsequent repotting. I recycle almost all of my pumice, haven’t had to buy new pumice in years.
Hi , just giving my 5pence worth , when I have collected In past I make sure all the soil surrounding roots is dug from where it came , if I plant straight into ground to forget about I will altars her und root ball , i hear people encouraging with heat mat under roots
, not sure about this one , I might be wrong , I would say transplanting straight into ground is far better to keep her under the same conditions as you collected her from , one thing I can say is this , it is all a learning curve , my advice is if you collect straight from wild and you are not sure or not able to get substrate needed then transplant straight into ground , giving her some protections from extremes , same light she grew up with , (position etc ) , sometimes the more we try the more we hurt them , if I am unsure or there is so much conflicting knowledge on them I will as said simply transplant , don’t give up and don’t knock yourself , but if you are unsure then simply transplant into ground and let her do her thing , chin up buddy
