Makes good sense! Gone are the days when you could reasonably safely send clones around in the post... seeds are about the only practical way to share anymore- and good onya for being so community minded.

Yes, you're quite right... a grow op does chain you down to some degree, but there's a lot of things that can be automated.

Watering clones isn't one of those where I've managed any automation yet. Unfortunately, due to the continuous output nature of my op, I can't think of a whole week that's gone by where I have not had cuttings in the clonebox.

However, my mums and flowering areas can go for about 6-7 days without being touched on their own reservoirs. I have recently added a system that recovers water from my dehumidifier and puts it in the tanks automatically, timed to top the tanks in between the times that they are flooding my trays to avoid overflow. This extends the unattended operation to about 12-13 days at a stretch.... provided the dehumidifier continues to trap water at the usual rate of 10L per day... and nothing silly like an air bubble in a pump stops a tray from being flooded. Real buzzkill, that. Frequent checking of the op is the only 100% sure thing.

If you haven't planned your watering system yet, flood types are the most reliable. They're mechanically simpler than most other systems and simply can't clog like systems that pump nutes through small spray or drip apertures. Much less maintenance.
