Next we were shown the hydroponics. This works really well, we were told, for broad leaf plants.
Basically, you mix the fertilizer with water and fill a fish tank. You use a standard bubbler to aerate the water. You germinate the seeds in some foam (I forget the name, but it is that fertilized foam I have seen at Home Depot), and when the seedlings have sprouted, transfer them.
It is recommended that you keep the fish tank (or other container, she showed us a 20 gallon planter doing the same thing with a much larger plant!), dark, because the fertilized water, when exposed to sun, will encourage algae growth...
I might try this with my basil when I get back!
We were taken into the next section of the greenhouse. Here is a tomato plant that holds two world records. It is that tomato tree you see to the left on the ride. (not the one in my picture!).
This plant holds the record as the largest single tomato plant in the world.
It also holds the record for the largest single harvest off a single tomato plant, at 32,000 tomatoes.
Wha?!
They have a system here where they “train” the tomato vine to grow in a large circle. Very cool.
We got to sample some cucumbers, very tasty! And, she showed off the mold used to create the Mickey Cucumbers!
It seems, however, that the cucumbers in the mold create so much pressure as they build up water, they sometimes will snap the molds!
So, they don’t make as many Mickey cucumbers as they used to...
And then some melons. Really, really large melons.
40 lb ones in fact. By hanging them like that, the melons actually tend to grow consistently round. Well, except for one that seems to be the black sheep of the crop, that is curved like a pickle.
They aren’t sure why...but when he harvests, they are going to try and figure it out!
We also learned that the sand “soil” isn’t just for show. It goes down at least 4 feet, pure sand. Sand is easier, actually, to grow in, as you can built tubing that directs the fertilized water straight at the roots of the plants, and the plants get it all, instead of soil sucking some of it up and retaining it.
But, it also brings with it these little microscopic worms that attack the roots. Disney hasn’t figured out how to get rid of them, yet. So, they just manage around them, basically trying to “starve” them out through crop rotation. For example, Swiss Chard is not on the menu for these worms, so they cycle Swiss Chard around the greenhouse as a result.
So, now you know, when you ride the ride, why they have seemingly random spots of Swiss Chard!
We also got to see the lettuce display, where I got to ask a question that was always bothering me. How do they harvest it!?
Well, from the back, it makes more sense. Each one of these “gutters” can be removed by a team of two pretty easily. There is a rather wide pathway between the two racks.
But, from the ride, I couldn’t figure it out!
Now I know!
