My First Greenhouse

Friday, April 5th, 2024

my-first-greenhouse

This is my first greenhouse! My husband got it for me from Costco, but it took him 6 hours to put together, and the pre-drilled holes did not line up with the screws that sometimes bumped into each other and had to be drilled in a different location.

The spring loaded mechanism has a temperature sensor, that whenever it gets too hot, it expands and pops the roof door open, which is cool!

My New Greenhouse

Here is a 5-minute tour of my new greenhouse:

Having a greenhouse expands your growing season by being able to start seeds early without having to buy grow lights, especially if you don’t have the indoor space to do it.

I got trays to go under the small plastic containers, where I placed seed starter soil and wet the soil before planting the seeds to the correct depth. Then I labeled each pot with a black Sharpie marker on a popsicle stick.

I’m growing more green beans this year, as well as bell peppers that did well last year. Cucumbers did well in a somewhat shaded area that other seeds did not do well in, so I will grow cucumbers again in that first raised bed I showed you last year.

Place your greenhouse in a sunny location if you can, close to your house so you can keep an eye on the moisture of the seedlings, that they don’t dry out before they germinate. Also place an outdoor thermometer in the greenhouse so you can see what the temperature is. One day it was cold, and I placed a large pot of hot water with the lid on, into the greenhouse and set it on the ground. The heat ematated up from it for several hours to keep the seedlings warm.

Bible Rocks and Minerals

Sunday, November 13th, 2022

Bible-Rocks-and-Minerals

I’ve recently noticed many places in Scripture that mention rocks and minerals. Years ago we purchased The Geology of Israel and Rocks and Minerals of the Bible from Northwest Treasures, which is a set of rocks and minerals that is specific to the Scriptures and to Israel, along with a binder with information about the rocks contained in the set. My kids gathered around to look at each rock and mineral to better understand, in a tangible way, the rocks referred to in Scripture.

Today I’m going to show you my two favorite rocks and minerals passages in Scripture: the precious stones in the Levitical priest’s garments and the precious stones referred to in the New Jerusalem that descends from heaven in the book of Revelation.

Precious Stones of Levitical Priest

I’ve always been fascinated by the precious stones in the high priest’s breastplate, which is described in Exodus 28:17-20. These stones were to be put into the beautiful woven garment that was for Aaron, the high priest. Each one of these rocks represents a different tribe of Israel, starting with Ruben (the oldest), all the way down to Benjamin (the youngest.)

We are going to look at some of these rocks and minerals today:

You can also do a craft for the breastplate of the high priest with shiny bronze paper and plastic gems to represent each color of the precious stones listed in Scripture. I give instructions on how to do this craft here:

Precious Stones from Revelation

My other favorite Scripture passage for the study of rocks and minerals is the New Jerusalem coming down out of heaven in Revelation 21:10-21.

The New Jerusalem is in the shape of a square, with three gates on each of the four sides. Each gate is an enormous pearl, and under each gate is a foundation stone. Each foundation stone is decorated with every kind of precious stone. These stones are mentioned: jasper, sapphire, chalcedony, emerald, sardonyx, sardius, chrysolite, beryl, topaz, chrysoprase, jacinth, and amethyst. Let me show you:

The length and width of the New Jerusalem is 1,500 miles across, so you have 500 miles for each foundation stone! Those are enormous foundation stones, one huge rock under each gate, holding up the walls of the New Jerusalem. The foundation stones are adorned with beautiful designs (maybe mosaics!) with only precious stones that glitter and sparkle in the light. God will be the Light of the city. You can see the precious stones adorning each foundation stone because the ground is transparent gold like glass! So the streets are clear, but they are shimmering because they are made from gold rather than sand, which is what window glass is made of. WOW.

We made a model of the New Jerusalem:

How to Grow a Hydroponic Herb Garden

Tuesday, July 12th, 2022

hydroponic-herb-garden

The plants in this hydroponic garden grow directly in water… with no soil. Every two weeks, the little green light on the bottom turns red to remind you to put two capfulls of plant food into the water. Other than that, you just top off the distilled water each day, and you get lucious herbs. Simple.

herbs-in-hydroponic-garden

My husband got me this one from Costco, but you can get them various places and under different brands. What they have in common is that they have pods that you place into the water. These pods contain seeds which germinate when placed in water under a grow light. The grow light on this model (Aerogarden) is adjustable. You place it lower when the seeds are germinating, and as they grow taller, you raise the light higher.

How to Set Up Your Hydroponic Garden

Here is a tutorial on how to use your hydroponic herb garden:

As you can see, you fill the container with distilled water, so as not to crust over the system with harsh chemicals from tapwater. Then put the lid on, and place the herb pods into the circles.

herb-pods-for-hydroponic-garden

Place the little “greenhouse” over each pod until they sprout. Then remove the “greenhouse,” allowing the plant to grow taller.

When the herbs are so tall that they touch the light, they need to be trimmed or transplanted to another container or outside.

So far we have grown herbs (including basil, parsley, and mint) and some cherry tomatoes. It’s fun to add some greenery to your home, and to have herbs available to clipping and throw into your cooking!

Starting Vegetables from Seeds

Tuesday, May 10th, 2022

starting-vegetables-from-seeds

It’s been a while since I’ve started vegetables from seeds, so I thought I would try it again this year. We planted these back in March, so now that it’s May, we have transplanted the seedlings outside. We filmed the entire process, giving tips along the way. Make sure to check your weather forecast to make sure that it will not freeze overnight in your area before transporting the plants outside.

I show you in this video the whole process of starting vegetables from seeds:

  • We planted the seeds in seed trays, using seed starting mix instead of regular soil, because the seed starting mix keeps moist better. You can use old yogurt containers or other small containers instead of seed trays.
  • Make sure to have a grow light, which has the full spectrum of sunlight so that the seeds can get off to a good start. Otherwise you can place them in a sunny window.
  • Put cellophane over the rows of seeds, to keep the seeds moist and to cut down on the amount of times you need to water them.
  • Use a spray bottle to water, so that the seeds don’t get washed away.
  • Some seeds grow faster than others. Some take a few weeks to germinate. As you can see in the video, the green bean plant sprouted high above the others, reminding me of the Jack and the Beanstalk story!

Starting Vegetables from Seeds (video tutorial)

After a couple of months, you will want to transplant the seedlings outside. Some of the plants were getting too tall for the grow light, but the frost outdoors hadn’t passed yet, so I just transplanted the taller seedlings into larger containers and placed them in a sunny window.

transported-seedlings

I have a raised garden bed in partial shade, so I chose veggies that like the shade, such as lettuce and spinach, to plant in it. Then I set up a trellis next to my house, and I planted the climbing varieties of vegetables along the trellis. Green beans, for example, need a structure to climb up. You might want to stake those up with a wooden shishkabob skewer like I did in the house in the sunny window, using a twist tie to make sure they don’t fall over.

Growing your own vegetables is a great way to eat healthier and tastier food. I will be growing an even larger vegetable garden next year!
