I had thought of that. Only thing is I'd have to cut them lengthwise because their 2 foot wide and I don't want to deal with with the cost and work of filling something that tall. I have cut sheets like that lengthwise and it's no fun at all.
I cut those three 2x8 boards for the top, shortest bed already. Going to do two more 30" beds, each one slightly longer because one end of the little front yard garden is at an angle.
Then I'm going to basically treat then like Square Foot Gardening and get my feet wet with succession gardening and rotation. It's the next natural progression and will help when I do get to growing in the tunnel.
And I thought I had hard water troubles. Ruins all the faucets.
Winter ended a week ago here in Central Connecticut. It’s now early spring.
Time to get out there
