Heh. You have pretty much the EXACT same stuff I do, even down the Lowes 5 gallon buckets. I used Botinacare Coco Bales. I'm really struggling. All my plants in CoCo are dying an ugly death. Make sure you drill a lot of holes on the BOTTOM and SIDE. The other thing i've learned is to water as slow as possible. 80% of what I pour in, runs out and is just wasted nutes and water, I think this makes the margin of error with CoCo very small. My plants in soil are kicking ass, my plants in Coco are drying rapidly. If use the Botincare coco bales rinse them, then rinse them again, then risnse them again, then rinse.... Trying to break the back of the salt and PH in coco is hard as phuck. Hardest medium i've ever used.
