The lyine Dutch Bucket (also known as the Bato Bucket) system is an efficient hydroponics equipment for greenhouse,and is extremely suitable for larger, long-term crops such as vine tomatoes, peppers (capsicum), cucumbers and other plants. You can use just about any type of growing media, including expanded clay pellets, perlite, and coconut coir. The overflow outlet can be connected into a central 1-1/2-in PVC drainpipe. The bucket has a highly effective internal discharge system. By installing the two elbows, the overflow water is suctioned from the lowest level of the bucket and discharged into the central drainpipe. This will eliminate the pooling of stagnant water. Dutch Buckets are made from food-grade polypropylene.
