Yes... it was a lot of fun... and had Jimmy Carter not de-regulated N/gas (the way we heated the greenhouses)...
Which gave the folks down in 'the valley' (the most southern part of the state of Texas) a huge financial advantage...
I may well still be running a greenhouse growing operation outside Houston.
One does, however, have to look at the numbers and make decisions...
And it was obvious I was attempting to win a horse-race with a nag, so to say.
Sold the operation to someone who wanted to do it...
And yes, it was a lot of fun!
Even without GM plants or digital controls...
Do you have a copy of 'Exotica'... the 3" thick book that details EVERY plant that mankind knows of... that grows on earth? Interesting book...
BTW: we did orchids for a while... finicky things... yet figured them out!
