While waiting for the lettuce seeds to grow, I started to rethink my process. I don’t think I needed to spend nearly $40 on a hydroponics bucket kit. Instead of a deep water culture setup, with lots of air bubbles, I decided to try the “Kratky” method. It is extremely low maintenance, but should produce similar results. Now that I don’t need to run an air pump, this should be quieter and cheaper too. The new plan is for five one-gallon containers, instead one five-gallon bucket. Being easier to move, that also makes the project more manageable.

Calculating the Pythagorean Theorem is classic assignment of a high school Geometry class. The fifth installment of a free Hype template makes short work of that task. A2+B2=C2 is easy to remember, but it can tedious to figure out – square the two known numbers, add those numbers, and then find the square root. Even with a calculator, keeping track of all the variables can be tricky. But with this template, it’s simply a matter of moving two sliders.
Less than two weeks into my hydroponics project, I can easily surmise the life of a farmer. It’s hard work. Now that all of the supplies are here, I can start growing lettuce. This is shaping up to become one expensive salad. I just don’t get how lettuce is so cheap. With all of the details involved in this project, I’m surprised that a head of lettuce isn’t $10. The next time I walk into a grocery store, I feel like I’m going to have a much different perspective.
In the year 2010, the iPhone 4 was a revolutionary device. It reshaped the way the world communicated. But in 2016, the iPhone 4 is obsolete – no longer supported by Apple. I needed a new phone. I skipped the 4S, 5, 5S, 6 and 6S models. That’s five generations of upgrades. It wasn’t until 5 1/2 years later, with the launch of the iPhone SE, that I felt there was a worthy successor. So how is the new phone? It’s nice! 🙂
Last Thursday (on March 31, 2016) Tesla started taking preorders for the Model 3. Starting at $35,000 – the Model 3 is the affordable version of Tesla’s all-electric vehicles. I was seriously considering joining in on the excitement. But at the last moment, I hesitated. Something seemed wrong. Did Elon Musk seriously expect me to put down $1,000 on a car that I didn’t even see?
