And then there were three

These are great ideas for your area. Just getting into gardening but I think my climate is not as harsh as yours, besides I’m trying hydroponics.

I watched a video re: using barrels for the hydroponics… it was quite interesting.

I’m in Zone 5b or 6a

Debbie,

You’re really going great guns on these! You should have plenty of fresh produce.

Any chance you could show a link to the automatic window opener?

Very happy with it

Thanks Debbie.

No problem ..
I look forward to seeing how you use it

Is it my imagination, or each new unit is larger than its predecessor? The varied designs should give you some indications as to the strengths and weakness of each design, and how to compensate next year. I showed my wife the previous two. We wish we had the right conditions here to do the same.

In a week or two we should no longer be experiencing overnight freezing temps and can move our seedlings into the greenhouse. However, it looks like we are not going to have a great growing season. Crossing fingers and toes.

@retired_guru_tech … you are correct in that each cold frame is different.
CF #1 is three windows wide.
CF#2 is two windows plus a small one
CF#3 is one window plus a small one.

They are all built to the same plans, just different lengths.
They, also, have different weather conditions.

1. gets full sun for most of the day.
2. is pretty shaded and has a small window of sunlight.
3. gets the same sunlight exposure as #1 except that it sits beneath a bush that will give it shade once the leaves appear.

I have purchased three thermometers that will measure the high/lows of the day but haven’t gotten them in yet.
Tonight and tomorrow night are supposed to be freezing temps
So it will be a good test. One of the thermometers will be going under a row cover that I am also using for the first time.
Let the experiment begin!!

This is great! I look forward to seeing your results.

me, too, RGT .. me too !!!!
Crossing lots of fingers that everything survives the freeze and that my “season extenders” make a difference.

Here is my little experiment that I did with my season extenders: "": https://www.facebook.com/groups/205089057306063/permalink/264720451342923/

I love these things.

Now to really twist your brain, think about making them vertical for a tower garden. ?

I watched a bunch of videos on how to make them today. I think I want to try it. Next I’ll need a vertical greenhouse.

Interesting that you say that.
I used to have a metal-frame, shelving greenhouse with a plastic cover. After many years of use, the plastic ended up in the garbage.

I just found a replacement plastic on amazon and was really excited until I found out that “somebody” through out the frame/shelving.

So, now, SOMEBODY has to build me a new shelving greenhouse. The great thing about the metal frame one was that I could set it up in the house, wheel it around, and then take it all outside when the weather got nice!!
