I continue to be amazed at how ready & willing you all are to help. Thank you for so much good advice!
After considering all the information, I've decided ordering clear, slotted, air cone pots is the most fool-proof approach for me to address my drainage issue.
To get a better quality bark, I will have to mail order. Since I do have 1/2" coconut husk chips available, can I use it instead of bark for a mix of 1/3 coco husk, 1/3 charcoal, 1/3 lava rock? If I must use bark, what size bark chips do Phals need?
If anyone would recommend reputable, affordable online sources for these supplies, I will appreciate your private messages.
