Yes, but those are not “fresh” foods. They can be grown seasonally and stored for use throughout the year. That’s why the worries about how much electric power it would take to make all farming indoors is moot. Growing only greens aeroponically, the electric cost is partially offset by lower costs for fertilizer and pesticides, and the add to the electric demand manageable.
I humbly disagree.
Lighting is the key to growing anything. The cost of artificial lighting is huge. The sun is free as electricity becomes evermore expensive.
Climate control is also expensive. For most of us it is the most expensive bill of the month. Same for hydroponics. Plants must be kept at an optimal temperature for optimal growth.
Do you employ a pest control company that periodically comes to spray for bugs, inside & out of your house? Bugs will find juicy vegetables even if you lock them in a vault. In a climate controlled environment there is no winter, so bugs never go dormant. Pest control is a must for hydroponic operations, yet it never kills every last bug. Disease, fungus, & bacteria must also be dealt with.
Water used must be at least partially purified & heated to optimal temperature, & kept that way.
All of this runs on electricity.
Without a backup power supply, the indoor gardener is at the mercy of bad weather & the power company. A day or 2 without power produces a dead crop - no water circulation, light, or temperature control.
Browse any Hydro store on the Net & you will see a multitude of expensive items necessary for a successful operation. Any vegetables produced hydroponically will be expensive.
