Float System Production of Lettuce

Float systems are really cool, but tend to be limited to low growing plants. I've grown a few herbs in float systems and using the small kiddie pool I did tomatoes a couple of years ago but I didn't solve the support problem very well.

Wicking Baskets: Pretty Cool!

This is a fun little video about building a kind of a wick system. It would not be difficult to transform this into a true hydroponics system by replacing the soil and the wicking material with passive medium and watering with hydroponics nutrients in the water. I'll have to try a design like this. It looks like it would likely beat the kind of wicking system I've used in the past.

The Mini Jungle Saga Continues — Tiny Tomatoes

Not sure what to do with this little mini-jungle that's been developing.  One problem is that it has now reached the point where it might be unsustainable since it's gobbling up nutrient at about a gallon a day, well maybe a smidge less.  If you forget to check the plants can get droopy really fast.  This afternoon I went to check that the rockwool was getting fairly dry (I must have forgotten to put nutrient on them yesterday) so I filled the tray and after a couple of hours they were back.  But I imagine that that kind of stress is not good for them.

Now they have little tomatoes on a lot of them, which makes them all that much more difficult to just sacrifice.  See picture.  Jessica found a bunch of pots and is lobbying to put them into pots.  That might work but the shock from separating the plants might be a problem.

I'm currently thinking of it as an experiment in plant crowding.  How's that for a rationale for screwing up?  It's also an experiment in just adding nutrient to rockwool without any flow.  The oxygenation doesn't seem as if it ought to be very good, but the plants don't look all that bad given the crowding and the sporadic watering.
