How to Build A Hot-House Tomato Cage for Early Spring:
Be the First with Ripe Tomatoes!
These cages can be built in 5 minutes. They will allow you to get your tomatoes into the garden a lot earlier. It works. I use a few every year and am the first in the area with red tomatoes. Try it! I original put this on my other blog but wanted to elaborate some of the ideas here.
Wind BreakThey act as a wind break and keep the plant from cooling from winds. They also allow transplants time to get used to the elements without becoming over-stressed. It makes a mini shelter for them.
Heats During the Day
They will collect the solar heat of the day. A sunny day in the 40's can easily heat the cage into the 70's. At night I recommend putting a plate on top, a few hours before the sun sets, so it stores up some heat. It is also important to remove it on sunny days in the morning. The inside of the cages can over heat on sunny days.
Water Container Heat Storage
I will be doing a new video that adds in a black painted milk jug at the bottom like in the picture. The milk jug is filled with water and it will radiate heat at night to help maintain a bit more warmth. They day time heat is quickly loss when the sun goes down. Maintaining warmer night temperatures helps prevent the tomato from going dormant so to speak.
In the event of a light frost a cage with a sealed top will give your tomato a few degrees of frost protection. The milk jug with it will help out even more!
Plenty of Room and Light
The tomato can grow and get plenty of light. Some early systems filter out light and plants can get spindly or the aren't high enough and plants out grow them before the right temperatures arrive. They grow out of their protection.
Black Plastic (Another trick)
You can also lay a piece of black plastic on the ground with a hole in the middle for the tomato. The cage can go on the plastic and it will warm the soil. A tomato also needs warm roots to start growing or it will sit and wait for the right temperature.
