I was going to start growing djshorts grape kush with this hydroponic setup (http://www.1stmarijuanagrowerspage.com/hydroponics-3.html) and i am trying to hide it so i was going to put it in a growbox in my closet. I was wondering if i needed a lot of ventilation since the airpump pumps air directly on the roots. Please let me know what you think. thanks
The leaves need plenty of air, too. Those air pumps generally don't put out nearly enough air to exchange air in a grow box. Use computer fans.
HIGH All, the air pumps are for your Bubble Bucket...not for ventilation..what type of light you useing? If you give us All the info you know, It'll help us help you better.
