Moneymaker is the most planted greenhouse variety in Europe. Too me it tastes OK, but not great. But it is supposed to do great in hot , humid conditions like inside a greenhouse. My daughter grew it in Guam while she was stationed there, and that is one of the most humid places on earth, all the buildings are covered with mold.

The distinction of greenhouse vs. outside growing is not well defined IMO. I grow ALL of my 130 heirloom varieties in greenhouses because they all perform better there- Much higher percentage marketable fruit. I grow hybrid varieties as well, many with "Greenhouse" labels attached to their labels and they do well too.

If I were to suggest a few varieties that many have found best performers my suggestions would be:
Prudens Purple- earlier and more productive than Brandywine
Cherokee Purple- distinctive and good production
Pineapple- consistent bicolor production
Black from Tula- doesn't crack much under GH conditions

But since growing heirlooms now for years in greenhouses I just won't grow them outside. There are a few determinate hybrids that can take the harsh outside conditions much better.

Hi barrie, Can you tell the yield of the above mentioned heirlooms in your Greenhouse and please suggest a little longer list of Heirlooms with good yield in the GH. Thanks.

If greenhouse means an environment with climate control (perfect lighting and ideal temperatures), then any and every tomato should grow in it better even best.

My point exactly, Sey. There are a few complaints from some folks in southern states that the temps under film just are too high even when sides are rolled up and shade cloths are used.

I will be using cooling pads and fan system and outside shade cloth to lower the temp in the GH. I will use heaters and circulation fans in winter. I don't know if it should be called a greenhouse or a high tunnel if i'll be using these two things for cooling and heating.

digdirt2, barrie, i live in a 9a zone in middle east. The temps in winter goes to 32f at night and 60f in the day, and temps in summer goes to 110f for a month but mostly remains below 100f. I am starting a hydroponic GH after this winter, dimensions are:

Area: 50x110, Walls: 8 feet, Ceiling: 11 feet,

I will use circulation fans, cooling pads and fans, and heater for cooling and heating the GH. Sides will be open in the mild weather with insect net installed and completely closed in extreme cold or hot weather. I'm still unsure about single or double poly as temps here rarely goes below 32f at night for couple of hours. I'll be growing cherry and beef tomato mainly, and also bell pepper as a trial (bcz people say its difficult to grow) with red, orange, yellow, purple and indigo colors (so if anyone here grows these too then it will be great to get the advice).

Superstores here purchase cherry tomato at $1.6/lbs, beef tomato at just $0.4/lbs and bell pepper at $2/lbs. Labor cost is around $250/month per person.

The farm is located 18 miles away from my home so i won't be there at night and i don't expect the employee to wake up at night and check the fire or GH although he will be living at the farm.

So these are the conditions in which i will be working.

Thanks Dave !!
