We fully endorse and support the Ecothrive range of coco and coco mixes and also stock the every faithful Canna Coco. For straight coco options we recommend the Ecothrive coco which has Charge mixed in at 2% or Canna coco if you don't want charge or want to add your own desired amount.
For larger pots and for use in drip systems etc we recommend a coco mix, either the Ecothrive coco and clay 60/40 mix or the coco lite mix from Ecothrive with 30% perlite and 1% Charge.
