Hi All. I'm doing a redesign for a grow computer.

In September [1], you posted about designing it, were asked some very good
questions about what you were trying to accomplish, yet didn't respond. Was
it a failure, and now it's being redesigned? Perhaps responding to the
questions may have helped.

I would like any input
concerning functions you would like to see it do. Here's a list of
functions so far:

Sense and control watering based on time or sensors.

Will each plant have it's own sensor and controller? They all have
different watering needs, you know.

Sense and control heaters in case of freezing.

So, heaters will only be required "in case of freezing"? What kind of
plants are you growing?

Sense and average light levels to determine fertilizer requirements.

Since when is light the determining factor in fertilizer requirements?

Communication system (power line/radio) for remote control.

I thought it was a computer? Is the computer going to sit outside in your
garden? How will you protect it, the communications equipment, and the
sensors, from the elements? It doesn't sound very cost-effective to me.


Is there some way to determine grow rates that can be incorporated?

Sure. How about: get off your ass and watch the plants with your eyes,
instead of trying to do it with a computer?

Any input will be appreciated.

See above.

Thanks in advance

You're welcome.
