Introduction A substrate growing system is a hydroponic system where the root zone is physically supported by media. The plants are fed by applying nutrient solution to the media. This system is in contrast to an NFT (nutrient film technique)...
Rocky, a commercial strawberry grower, started experimenting with hydroponicsin the open in 1978. He set up an N.F.T. (nutrient film technique) systemusing 90mm PVC pipes as channels. With this system he achieved a muchhigher plant density compared...
Growing hydroponic tomatoes in Northeast Washington State has been a worthy challenge for Jack Benjamin at Benjamin Farms. Having a close proximity to Spokane, Washington makes it convenient for delivering vine-ripened tomatoes for $1.99 all...
Come rain, shine or even strong winds, Tom Jopson's tomatoes grow no matter what the weather has to offer. And they are in season from the end of October through July, which is the off season for most tomatoes. That's because Jopson's tomatoes...
