I just started the Prepara Pro a couple days ago with 4 pods of lettuce and 2 pods of mini bell peppers. Three of the four lettuce pods have already sprouted.
So far I like it and have it sitting between the 2 AGs on my dining room table for the light. I plan to move it to my bookshelf garden once I order another grow light.
I was startled the first time the machine rotated the plants. But other than that, it is very quiet, which I like. And I also like the little "trellises" that you can pull up on each pod to help support the plant if it needs it. They're not very tall, but if a plant is leaning, that should help. The one thing I do not like is that you add water or nutrient by pouring it over the grow surface -- that's kind of messy and leaves spots all over it.
I just ordered a couple of Preparas, got a special for the deluxe kit + light for $60 and no rape fee shipping to Alaska. I was curious how your garden turned out?
