I've got a pack of green bags called FLower Pouch (http://www.flower-pouch.com/S1GB.html) to plant up as per hanging baskets.it comes with a sachet of swellgel and feed to mix with soilless compost ( not included !).

I've not seen soilless compost around - anyone know where to buy it?

or can I just use potting or standard compost mixed with some perlite instead?

thanks:)
