when i cultivated mine, i got a bathroom soap washer and used the netting, some stainless steal scissors and some tiny rubberbands left over when i had braces. heres what i did
1. cut the stalk.
2. hold it infront of the powerhead for a few seconds to get the " goo " off.
3. find a rock with a little indent in the middle of it.
4. place the stretchy netting over the xenia. ( leave a little room so your not squishing it ).
5. add the rubberbands so there are no oppenings around the rock.
6. wait a week and look at the rock threw the glass to see if u can see the stalk attached.
7. cut rubberbands and u should have a healthy frag.
