If you are interested in growing hydroponic blackberries, blueberries, raspberries or strawberries in a greenhouse there really isn't a whole lot of reference materials that I have found on commercial hydroponic nutrient applications. We took a "we'll try these" approach and so far so good:
Blackberries / Strawberries / Raspberries
Flora Micro / Flora Grow during vegitative state at 10ml/gallon
Flora Micro / Flora Bloom during transition and flowering state at 10ml/gallon
Diamond Nectar at 10ml/gallon
Liquid Karma at 10ml/gallon
Sweet (Berry) at 15ml/gallon
Cal-Mag at 8ml/gallon
Flora Kleen at 5ml/gallon
pH at 6.6-6.8
Blueberries - same as above except pH at 4.9-5.1
If you have other ideas or formulas that work, please let us know. We started the plants we received from Burpee at one half of these formulations just to get them started. We changed to full strength after three weeks.
