I have been using a fogponic set up for around 3 years now and have never had any problems and my plants grow quicker. As soon as the seedling emerges it goes into a net pot and then straight into my aeropod with the fogger positioned in the middle and then I fill up the pod with solution until it is around 1 inch above the fogger nozzle. Set the timer for on for 15 mins off for 15 mins using a non digital timer 24/7 and you will get very quick growth rates. A good tip is to make up your solution in a big bucket as it is easier to set the PH level in a large mass of water then transfer what you need into your fogger set up.
