I can't really say as to the quality of some of the HF stuff. I have the automatic regulators on mine so I don't manually adjust them. I only till the piles in the spring once before using the planter. I agree, too much tension on the springs can cause over-regulation on the secondary side of the system if the piles aren't tilled properly. The carbon dioxide works best in 2 levels.
