Is it economies of scale?
Does anyone else find that their hydro is prohibitively expensive? I have a very small kit - a Baby Bloomer, which is a 6 gallon reservoir with a container with 10 pots on top. Between the electricity, the nutrients and all the water, these are the the most expensive veggies on the planet.
Part of the problem is that I used the wrong seeds this time and put in a full sized tomato. I know pulling that will help, because it sucks up a gallon a day plus the nutrients to go with. So that's one thing. But still...
I've been using liquid nutrients because I was so disenchanted with by powdered version. It *wouldn't* dissolve. I used warm (then hot!) water, a blend, an airstone...and still 90 percent of it was in the bottom of the reservoir.
I also wonder about scale - growing so few plants may add to the cost?
Anyone have any advice about making this more economical while keeping it a low key venture that requires no more than a few minutes a day?
Thanks for your thoughts.
