Jim,
I seeded some chives over a month ago and have been surprised at their
slow growth rate. Germination was also very low - do they need cool
temperatures to germinate?

Dear Gordon:
I plan to visit Adriana when I go to Florida in the next month or two, and
I'm really looking forward to that.
However, I need a system without Perlite, which is unavailable here in
Costa Rica (that I know of). We have coconut coir, volcanic rock and rice
husks, and I think perhaps a combination of all three might do the trick.
Any advice there?
Has anyone used Bamboo as you would a gutter or PVC pipe system?
Jose

Jose (and Gordon),
I'm wondering if sugarcane bagasse could be used as a hydroponic media.
I've heard of rice husks being used successfully. With coir you have to
be sure any salt has been leached out of it.
As to guttters, I think you greatly compromise yield using gutters
rather than trays or troughs.

Jose Tatsoi is an oriental green (of the cabbage family I believe) which
has dark green spoon-shaped leaves which grow in florets. It's one of
my favority salad green ingredients. If you haven't done so already,
get yourself a copy of Johnnys Selected Seeds commercial catalog
(www.johnnyseeds.com), then we can refer you to a picture. Hey, 10
months ago I didn't know what tatsoi was either...

I experienced similar difficulties starting chives from seed. The quickest
and easiest way is to find someone willing to share a few divisions from
mature plants. They multiply rapidly and cuttings can be taken almost
immediatly.

Johan,
I would love to hear more about your set-up for strawberry growing. I
was under the impression that hydroponic strawberries were not an
economically feasible crop. With the phase-out of methyl bromate in the
next year or so there will be a lot of interest in alternatives to
field-grown or soil-grown strawberries.

Adriana,
Mine are 'hand me downs' from my grandmother's gardens, so I'm not much
help on starting from seed. They grow like wild onions once you have
them started, so hang in there. That's why they were one of my earliest
trials in my little wall unit system. I'd still have them if it wasn't
for the smell.
I can't stand the smell of raw onions, garlic, or the taste of
tomatoes, though I love growing them.
Her old house at Crenshaw has any number of strange alliums growing
wild around the hothouse site, flower beds, and garden plots. I've
thought of culturing several unusual varieties commercially.

Hello Adriana. The flood and drain is my original 2-liter bottle setup and
it works well. It appears it's the 'PROCESS' that creates the differences in
results - so I'm working to correct that in the 2-liter flood and drain
setup. Besides, I like the convenience of the small 2-liter containers
-allowing me grow many different plants, each in a secure pot. joel
In a message dated 99-05-21 08:55:38 EDT, you write:
<< That's very interesting Joel. It begs the question - why do flood and
drain at all if the results are so much better with constant drip?

Yes we tried Nasturtiums. Didn't work so well for us in our non-media
hydroponic system. Beds are more suited for Nasturtiums. Once we put them
on the grown they grew like weeds and covered very large areas, 25 to 100 sq
feet. Aphids love nasturtiums so it is better to put them further away to
act as a trap crop. Still lots of flowers to harvest for market.

I like various mixtures of volcanic rock and coir. Half and half seems good
for bag culture, 1 coir to 3 volcanic rock for my flood and drain. You need
to find the right mix for the climate based on rain and sun. I live on the
volcano here in Hawaii so volcanic rock (we call it cinder) is very
inexpensive.

Shepherd's Seeds has a nasturtium called Peach Melba that I've wanted to

You should not have any problem. I would suggest getting a copy of " Home
Aquaculture " 'A Guide To Backyard Fish Farming ' Amazon.com has it I
believe for around $16. You need to make sure you wash the vinyl liner well
before adding fish.
