Dutch Bucket Hydroponics - Tips & Expanding the Reservoir

In my current Dutch Bucket setup, I'm using 27 gallon reservoirs. They are matched up with 18-20 plants, not a very good ratio. So I'm having to constantly add water, about 10 gallons each day. I really need a larger reservoir. What I have done is add a 55 gallon plastic drum, connected by plastic tubing, and then hooked to a float valve in the reservoir. What this does is triple my overall capacity, thus enabling me to now put the system on a timer and spend my time doing other things. Also in this video I talk about using pump filters, using buckets without lids, my results with open-pollinated Big Beef, and some surprising things about Cherokee Purple tomatoes.My FB page: https://www.facebook.com/mhp.gardener
