This was from my most recent gig. Back when I used to do it "professionally".
Greenhouse #2 - wasn't heated, just used to store wood when we started. I ripped out the fabric on the ground and went to work with the compost and hand formed some raised beds. You can see Greenhouse #1 in the background, that's where the flowers and veggies were started.
We eventually ran drip lines.
This little run produced a lot of tomatoes...a LOT of tomatoes. I used to dread having to pick tomatoes before market day. At the end, we didn't "row" about a 10 foot long area and just planted flowers in mass to cut and sell as bouquets. It's unbelievably efficient to throw down straw...doesn't matter if it's old, but you get real value out of it by not having to weed (ever).

We also built a 90 by 24 foot Cold Frame. I didn't think that we would produce much out of it since we had a late start, but it turned out to be fantastic. The plastic and fabric make me cringe a little bit, but laid, cut, and staked it all by hand in one day since we were behind schedule. After laying miles of plastic behind a tractor, this is a little crummy but it sure did do the trick.
We ran double rows of drip tape down the plastic sections, which were gravity fed from a spring-fed pond, and put in the bi-pass valves to feed in fertilizer concentrate. The fabric in the aisles make it really nice...no weeding ever. We planted more tomatoes, tons of peppers, squash and zukes, and then a whole row of pumpkins that turned out to be a really good producers.
I don't have a final picture, but the pumpkins grew up to where we had installed the horizontal crossbars of the frame. Roll down sides and we put doors on eventually.
Ahhh...that was a good trip down memory lane!
