We have been steadily working on putting up a greenhouse at the farm. The goal is to have transplants started on Feburary 15th this year. With our new greenhouse, we will be able to supply certified organic transplants to the public and provide our own transplants.
Besides having the obvious structure of the greenhouse we have to buy the plastic for the top, fans for air circulation, and a heater. We will have electricity inside the greenhouse and water for keeping the plants alive. It's like building a small ecosystem.
Where are all the plants gonna sit? We put the seeds into flats, which are big plastic trays with individual seed cells. Once in the flat we place them on top of a table. The tables are really important. We've found the best design to be a rigid wooden frame on top of sawhorses so that two people can move them easily and we can put the table tops on the truck bed to transport to the field. Maximizing space in the greenhouse and easy mobility is key. We only have so much space in the greenhouse and we have to move the tables outside to get them ready to plant or when it's too hot in the summer.
So we decided as our Sunday fun-day project to build greenhouse tables. We have been building our own tables for 10+ years but now have perfected the perfect lightweight yet rigid design. Sometimes the tables hold almost 100lbs in plant material after they are watered!
In the picture you will see one assembled table. We built 15. Using construction adhesive and screws helps to ensure longevity.
All in all, with the use of a friend's table saw and a trip to get lumber, it took us just over 3 hours to complete them. Soon we'll affix metal hardware cloth to the top to give the flats of plants lots of support.
We will post more greenhouse building pictures soon!
