Default Looking for greenhouse info.


"Special Agent Melvin Purvis" wrote in message
...
My first attempt at growing vegatables in a small greenhouse, 8x10,
was a complete disaster. Nothing to show for it at all last year.

With a new year coming up I would like to start with a clean slate and
do it right. Can someone direct me to a book or a website that has
reliable information about greenhouse growing techniques? TIA.



The SA caught my eye so I had to answer.
read these:

Recommend you research Hydroponics, Its been growing GH
tomatoes/cukes( and many others) for years. The current state of
Hydroponics have given us many interesting innovations & practical
information
for many plants. So while the tricks and tips given here are valid,
they are so old school. ie. A 100 watt bulb is a great heat source for a
small area, say a dog house, but it is worthless on a green house of any
size except in the immediate 2-3 feet. If you are keeping the top of the
plant(s) warm with a light (& @ a safe distance to keep from cooking the
leaves) and knowing heat rises.... what is keeping the roots warm?

look at something simple like an ebb and flow or NFT system with a reservoir
that you can use an aquarium heater to maintain proper and constant root
temps, then you can cut down on trying to heat a large leaky (by design)
structure by heating the roots, not the air.

BTW Agent Purvis, You are hereby remanded to remedial Basic Agent report
writing class . Gather and document specific facts using the basic
interrogratives on your next GH adventure, what were the ambient/ soil
temps? Humidity? The type, quantity and schedule of nutrients?

Factual information will help you improve GH production.
