macedon-ranges-aquaponics: Hi All, I have often been criticized for the depths of my Deep Wate
macedon-ranges-aquaponics:Hi All, I have often been criticized for the depths of my Deep Water Aquaponic beds, comments to the nature of ‘too deep’ or ‘waste of water’ and even ‘un-traditional’ and some other far out there comments.But this is why we made them 450mm deep and not the traditional 150-200mm deep the literature recommends. It makes sense when you think about it, if a media based aquaponic bed is recommended to be a minimum of 300mm deep for adequate root growth, why make a deep water bed only 200mm deep!These celery roots reach the full 450mm depth of the grow beds, (nearly half a metre!) and 200mm outwards under the raft beside it. So much so that the net pots directly next to these need to be empty or risk being over run.Even at this depth, these roots still slow water flow significantly, and had the beds been shallow ones, these celery roots would have clogged the system up for sure. We are only pushing 1000ltrs per hour through these beds, so its not a great water flow as it is, but i will need to keep a very careful eye on this when the other seedlings begin to reach full size to make sure i have adequate water flow. Just something to think about.Have a safe weekend everyone, and WELCOME to all our new followers! Thanks very much for taking an interest in us, in means a lot to us!Regards -- source link
