I don't want to make you feel bad but if you had asked, before buying this system, and added how you were going to use it, I would have showed you how to build and plumb a drip system for less than 50 bucks....

Not saying that the system isn't good or won't work but just thinking you could have built the system and bought yourself a nice sack for the same price you bought that one for....

As far as EC levels go, don't let them get to you.... Keep ph and nutrient strength in check, and you will do alright.... There is plenty of time to find out how EC should fluctuate throughout the grow....
