Productivity of Commercial Systems
The productivity of commercial systems has risen dramatically in the past few years. Commercial tomato growers who once hoped to annually pick 20 pounds of tomatoes per plant are now picking as much as 35-40 pounds annually. In a 12,000 square foot greenhouse, a tomato grower can grow 4,0000—5,000 pounds of tomatoes every week. Lettuce growers are picking mature heads of lettuce in under 5 weeks and, with 20,000 square feet of growing space, can produce nearly 3,000 heads per week. The cost of establishing a commercial hydroponic greenhouse operation is quite reasonable when considering the potential profit and the intensive volume of high-quality produce that can be grown on a small lot.

YEAR ROUND GARDENING                    

GlassHut Greenhouse lighting systems

We Prepare your garden by adding at least 25 watts of cool white fluorescent per square foot more or less as needed. The idea is to keep continuous lighting on your plants. In our greenhouses, you can cut your lights off during a particularly sunny day. Lights, with all other needs met, is your only real gardening limitation. With supplemental fluorescent lighting you subsidize your cloudy days with nice healthy vegetative growth. At night, when the sun is down and most other plants are in a dormant state, your plants will be in continuous growth. In our greenhouses you can add as much light as needed for your garden, although I wouldn't suggest anymore than 70 watts of light per square foot. Then, when the plants reach the height at which they would normally begin to fruit, you recreate the lighting that the plant would have at the time of year it fruits. For example: You have been growing tomato clones, in an indoor area, for 1(one) month under 45 watts per square foot, continuous lighting. They have reached a height of 30"-36". Now, assume you live in an area where tomatoes grow from April until September, and they usually begin showing their baby tomatoes growths from July until early-mid September. Then calculate the average amount of light during the day, during those months. In the Southeast U.S. it adds up to about 13 hours of light and 11 hours of darkness per 24 hour day. So, after your 1(one) month of continuous growth,(24 hours a day, 7 days a week) you would switch your lights from 24/7 lights, to 13 hours of light, and 11 hours of darkness per day.

*For an herb garden, leave the lights on your favorite herb plants continuously until they reach their desired height, aroma, texture, and flavor.

 

GlassHut Greenhouse TEMPERATURE AND HUMIDITY CONTROL SYSTEMS

Temperature and humidity are usually very easily controlled with our environmental systems. Humidity is controlled by an installed ventilation fan, and Fogger system connected to a humidistat. The humidistat should be set at about 50% humidity. For temperature control we connect a  heater to a thermostat, during cold conditions. To cool the room we connect your thermostat to an installed ventilation fan. Keeping your temperature range from 75-90 degrees Fahrenheit. For your convenience, we install a humidistat/thermostat combination and connect to a single ventilation unit for climate and humidity control.

 

GlassHut Greenhouse GARDENING SUCCESS TIPS FOR YEAR ROUND

1) We make sure you have enough lighting for your plants growth. At least 25 watts of light per square foot.

2) Make sure your plants are at the usual height they begin to first bear fruit, before you switch from continuous lighting.

3)For an abundant herb garden harvest, simply leave your lights on continuously until they reach their desired harvest point.

4) We Ensure your humidity is at 40%-60% humidity(50% being optimal) by installing a ventilation fan, and fogger attached to a humidistat.

5) By adding a thermostat to a heater for cold conditions) or ventilation fan for warm conditions) we optimize your rooms temperature to 75 degrees Fahrenheit.

6) For added convenience we install a combination humidistat/thermostat to a single ventilation fan to control hot, humid conditions.

7) Monitor your plants growth and experiment a little to begin with. With practice, you too can grow your favorite vegetables indoors year round.

First we should start by understanding some greenhouse lingo.

Cold greenhouse, cool greenhouse and warm greenhouse are common terms you'll see quite often.

They aren't three different houses, only one with different temperatures maintained inside. Just a note, these minimum temperatures represent night temperatures, not temperatures maintained during the daytime. The sun heats a cold greenhouse and usually has a minimum temperature of 28 degrees F maintained. No growth occurs in this type of house but you can over winter plants that are not frost sensitive. Cool greenhouses are heated during the cooler months either with gas, oil or propane to a minimum temperature of 45 degrees F. This is just warm enough for a little plant growth and frost sensitive plants can be over wintered here. A warm greenhouse is where all the action is. This house is heated at night during most months and a minimum temperature of 55 degrees F is maintained. A wide assortment of plants can be grown during the winter, including exotic varieties and most vegetables. T. Our UV roofing and weatherized windows cut down on heating costs in Winter and cooling costs in Summer.

Cooling a greenhouse during spring and summer, where temperatures can reach well over 100 degrees, is just as important. Tomatoes for example will stop growing when the temperature starts to inch toward 90 degrees. That is where our environmental system comes in play.

If you live in an area with a short growing season, the cool weather could be upon you right when warm weather crops like tomatoes and peppers would be at their peak. Our greenhouse extends your short season so you too can enjoy a red ripe homegrown tomato. You can have an earlier crop, for example, harvesting in June instead of July or August. Tender varieties, which otherwise may not grow in your area, can be grown and enjoyed.

What vegetables can be grown in a greenhouse? Peppers, cucumbers, beans, eggplant, melons, squash and of course tomatoes do quite well. Carrots, lettuce and radish can also be grown inside. When searching through catalogues for seeds, look for varieties made specifically for greenhouse production. They will have qualities that will make growing them easier for you and assure your success. For example, 'Alicante' tomato is meant to grow in a cool greenhouse because it can tolerate cooler temperatures and 'Tornado' is an excellent bush type that stays compact, a good idea for the greenhouse.

Seed starting dates vary according to the vegetables grown and the type of house you are maintaining. For tomatoes growing in a warm greenhouse (min 55 degrees) start seeds in early January, transplant in February or early March into grow bags (bags filled with a  soil mix made especially for greenhouse vegetable growing) or plant into 5-gallon pots, then place them against the south side of the greenhouse. This area will get the most sun and heat during the day. You will start harvesting your crop in June. For a winter crop, start your seeds by July 1, transplant to bags by mid- September. Both pepper and cucumber seed are started in late February, transplanted in April for a late June harvest. Place these also on the south side. Our tinted UV roofing shades your greenhouse starting in spring and continues through summer as the temperatures can soar to 100 degrees quickly. All of these plants are going to need support at planting time. Tie stems to bamboo stakes.

Pollinating the crops becomes your job, as there are no bees inside to do the work. To pollinate tomatoes, tap on the bamboo stakes once in the morning and once at night when you notice the petals of the flower are curved back. You will have three days to achieve pollination once you notice the flower petals are curved. During the summer, try to maintain a temperature of 80 degrees during the day. Venting and shading will be necessary to accomplish this.

Remember everyone's season is different, so grow according to your areas climate. Manipulating the environment by heating in fall and winter and cooling in spring and summer is our way insure the proper growth of your vegetables so you can be harvesting all year long.
