What is the hardest aspect of hydroponic gardening?
The hardest part is in the research needed to know which produce will offer you the best return & naturally, all the technical knowledge for ensuring a bumper crop of hydroponics that will be definite your survival & be the envy of all other "preppers". There’s now lots of resources on the world wide web for hydroponic gardening advice though I admit that it can be confusing when trying to piece it all together. So better go for a best advise i.e. "Advanced Nutrients" it has many hydroponics flower and vegetable gardening articles on the site.
