Growing my tomatoes this year in a water sourced radiant heated soil root zone system.
My piping is 12” deep on 12” centers in a 30 x 96 single layer high tunnel
They’re about a foot tall so far and starting to flower. Trying to keep the soil temp around 70* but min / max thermometer shows my ambient air temp dropping to low 40’s some nights.
Most of the research I did was from cold weather states and the goal is to grow year round with supplemental light. Not using fake light now
I’m in the California foothills about 2000 ft elevation.
Everything seems to be working well but is my first season doing this.
Any ideas, knowledge appreciated
We started peppers, tomatoes and cukes indoors with racks and grow lights from Lowes on March 1. I'm astounded at how well they're doing.
We'll set these out in our raised beds, protected with hoops and heavy cloth as a cover-up this week. Frost last night in mid-Missouri but the big lake keeps us 10 degrees warmer than nearby.
I'll dig up some pix...
That is so cool!
If you haven’t read any of Elliot Coleman’s books on year-round growing, or ‘The Year-Round Vegetable Gardener’ by Niki Jabbour, I’d recommend them.
Elliot grows in Maine and Niki in Canada (I think?) They both make it look easy, LOL!
