whats your temps (inside tote and outside tote), do you have a fan blowin strait on them (clones dont like it, drys them out to fast), how close are your lights, when you have the netcup out does water get your finger wet when you first start to stick it in the whole (as stink says, works for the wife too), how far are the sprayers up or down from the lid, how long do they live, and whats the ppm of the water? I will try and help you figure out whats up. also whats the ambient temp day and night around the room there in. and does the tote sit on a concrete floor.
