1. Growing Plants in a Greenhouse and Management
2. First Things FirstWhere is your greenhouse going to be located?How big will your greenhouse be?What is your budget?What kind of accessories will your greenhouse need?
3. What is a Greenhouse?Definition: An indoor garden that’s temperature is controlled and protects different types of plants from the outdoor elements.Not just for utilitarian purposes:Area of relaxation with a table and chairsIncreases time for plants to grow before the season starts and after the season endsCan start propagating 30 days before the season starts and end 30 days after the season ends **Weather permitting**
4. Requirements for a Successful GreenhouseProper Ventilation and HeatingWatering SystemBench SpaceSize of the GreenhouseLocation of the Greenhouse
5. Commercial GreenhousesCommercial greenhouses are used to cultivate large numbers of plants to sell to consumersYear round plant growth
6. Types of Recreational GreenhousesRecreational Greenhouses are greenhouses that are used by individuals that grow plants as a hobby at homeAttachedEven-spanLean-toWindow-mountedFreestanding
7. Attached GreenhousesA greenhouse attached to another buildingEx: attached to the home or agriculture classroomTypesEven-spanLean-toWindow-mounted
8. Attached Greenhouse TypesEven-span:One end of the greenhouse is attached to another structurePro: Provides the most space Easy to lengthen if more space is neededCon: Usually the most costly
9. Attached Greenhouse TypesLean-to:Half of the length side of the greenhouse is connected to the side of a building from the floor to the crest of the roofPro: least expensive option Takes the least amount of space (smallest option)Con: Limited spaceHard to maintain an even temperature Need to make sure the greenhouse is positioned so that there is an even amount of sunlight hitting the greenhouse (make sure one side is not getting more sun than another side)
10. Attached Greenhouse TypesWindow-mountedExtension from either the south or east side of a house that gives one to two feet of lengthened space away from the house for plant growthPro: inexpensiveCon:Small space (smaller amount of space equals less number of plants fit in the greenhouse)
11. Freestanding GreenhousesA greenhouse separate from other buildings and stands on its ownPro:Can be made any sizeLower cost per square foot than attached greenhousesCon:Must install heating, electricity, and water source

13. How to Build a GreenhouseFrame Materials:Aluminum: Inexpensive and DurableMost Used by Texans and Most EconomicalWood: Inexpensive, but decaysMust be treated to resist decayCovering Materials:FiberglassPro: Inexpensive and DurableCon: Will get broken down in time by UV lightGlassPro: Best light qualityCon: Most Costly UpkeepPolyethylene Film (Most Economical)Pro: Cheapest Option and Low Required Frame MaterialsCon: Needs to be replaced about every 2 yearsHow to Build a Greenhouse Video
14. Management TechniquesSelecting the location and size of the greenhouseSolving for proper ventilation and heatingTemperature controlCooling and HeatingWatering System
15. Location of your GreenhouseMost desirable location:South or southeast because of the most sunlight in the winter months when it is naturally colder outsideThe location will determine:Structure sizeWhich types of plants you can growTake into consideration:Possible damage that could come from natural causes (Ex: storms or falling limbs from trees)The amount of sunlight in the area
16. Size of GreenhousesWidthImportant because it is typical to lengthen a greenhouse if you need more space instead of widen itThis will determine your walk space and bench spaceHeightDepends on the height of plantsLarge GreenhousesPro:Easier to control temperatureCon: more costly to buildSmall GreenhousesPro:Less expensiveCon: temperature fluctuates more quickly and more oftenLess room to expand
17. Watering SystemHand Watering:Pro: You regulate the water amount given to each plantCon: Possibility of under watering and plant water source depends on youMisters:Pro: Will provide adequate water sourceCon: Possibility of under or over water plants and increases humidityAutomatic Watering System: (On a timer)Pro: Plants always getting adequate water supplyCon: Some plants need different amounts of water than others
18. VentilationImportance:Reduce mildew and moldReduce harmful bug numbersHelps provide an ideal environment for plants to grow inExample of a Ventilation SystemMechanicalNaturalGreenhouse Ventilation VideoControl temperature during all seasons
19. Temperature Control: CoolingCooling: Prevention of Plants getting too hotOnly needed if Ventilation is NOT enough to keep plants coolExample: Hot summer months in the southShade is an inexpensive way to coolNatural tree coverRoll up/down shade covers to put over the greenhouse
20. Temperature Control: HeatHeating: Prevention of plants getting too coldOne of the highest expensesMeasured in British Thermal Units or BTU’sDepends on:The plants being grownGeographic location of your greenhouse Montana vs. Texas will have different requirementsAmount of direct sunlight hits the greenhouseWays to Heat:Heat coming from central unit in the main building (attached greenhouses only)Heat coils, solar panels, or natural sunlight
21. BenchesBenches: What plants are placed on within the greenhouseBench space: space where plants are placed to growBench height should NEVER be more than 36 inchesWhy?Benches should be accessible to individuals of all heights and wheelchair bound individualsBench Materials:ConcretePlasticMetalWoodBench Layout Types:Peninsular LayoutLongitudinal LayoutRolling/Non Stationary Bench Layout
22. Peninsular BenchesPro:Easy to keep plants separated in groupsProvides more space than Longitudinal BenchesCon:More difficult to water (more difficult arrangement to install a watering system)AisleBenchesBenches
23. Longitudinal BenchesPro:Easy to install a watering systemBest design for daily tasksCon:No as efficient use of floor space as the Peninsular and Rolling bench layoutAisleBenchBenchBenchBenchAisleAisle
24. Rolling BenchesPro:Provides the most spaceMost efficient design for use of floor spaceCon:Not recommended on a business level when benches are moved not all of the plants will be easily accessible to customersBenchesFree Space
25. Begin Growing!What kind of plants are you growing?They will need to grow in a soilless media with proper:Pore SpaceWater DrainageWater Holding Capacity
26. Remember!A successful Greenhouse requires:Proper VentilationWatering SystemTemperature RegulationLocation of the Greenhouse
27. Greenhouses Use Media, NOT SoilWhy?Field soil does NOT have good: Pore space Water drainageWater holding capacity to facilitate greenhouse plantsMedia Examples:PerliteBarkSandVermiculite
28. Soilless MediaPerliteSilicous material from Volcanic originGood for increased aeration and drainageBarkBi-products from any wood industry (paper, lumber, pulp, plywood)SandMedium to coarse textured is the best optioninexpensiveVermiculiteMicacious mineral created by heating to very high temperaturesHigh water drainage capacity, and good aeration and drainageNot as strong of a product as sand or perlite
29. Media RequirementsWater Holding CapacityDrainagePore SpaceThe amount of space between the solid components of the media and the plant rootsDetermines the medias ability to: Hold air and waterRate of gas exchange and drainageNo space small pores large poresGood to have large and small pores in the mediaLarge pores increase available water and drainage for the plant
30. Pest and Disease ControlNatural methods of pest control are highly recommended:Wash plants with clean water to eliminate any bugs or their eggsMove plants with mold or diseases into a dry areaIsolate plants to prevent the spread of pests or disease to other plantsBefore moving outdoor plants inside:Wash plants thoroughly with clean water to diminish the chance of bringing pests into the greenhouse
31. Plant SelectionPick plants the interest youMake sure different species of plants have similar requirementsTemperatureWateringMedia typeVegetable Greenhouse Video
32. Growing TipsBefore planting:Make sure media is NOT drySome types of media do not absorb moisture completely and multiple watering's are necessaryAdequate light levelsLow light = slow rootingHigh light = burning and drying of plant and its leavesAverage greenhouse temperature needs to be 70 degrees
33. Plastic Bottle GreenhouseMaterials:One 2 liter clear soda pop bottleArea with soilSeed or small sprouting plantDirections:Cut the bottom off of the bottleTake the top off (it will not be used)Plant the plant in the designated areaPlace the plastic bottle over the plantDONE! Water when neededRecommendations:Do not place plant in the direct sunlight that it could be damagingLate fall or early spring are the best times
