Our exterior light deprivation greenhouses are a great and economical way to get into the light dep game. Motors automate light cycles by rolling up and down the blackout tarp using a series of limit switches and timers. The end walls of the greenhouse are permanently blacked out to accommodate for this design. We personally have been using these greenhouses for many years with great success.
