Are there any advantages to your siphon drain over bell siphon? Where can I get lava rock in Orange Co.How does it affect PH and I assume it is cost effective. I am using 1/2 hydroton, 1/2 pea gravel to cut the cost. I use the cement mixing bins from HD and only have about 4" of grow medium height, but my plants seems to be doing well. see my videos. thanks in advance.
Yep Chip, that is about it. Whatever works well for you. There are so many different little details that affect everything that it can become really hard to make short, generalized, definitive statements.
