The AirDomes will not dry the plants out. Take a look at our brochure on the home page and the instructions in the AirDome section. Remember to use a "fluffy" mix to maximise the effectiveness of the AirDome. I would suggest growing in 50% good quality compost or coco mixed with 50% perlite. Plant up, allow the plant to establish in the pot for 2 weeks and then turn the AirDomes on. Hope this helps………Josh
