What is the Meaning of Grow House?

What is the meaning of grow house?

A grow house or grow op refers to a residential building or outbuilding used for the illegal cultivation of cannabis plants. It is essentially an indoor grow operation set up within a house or other structure.

Some key characteristics of grow houses:

  • Windows are blacked out to prevent light from escaping

How Big is a Grow House?

The size of a grow house can vary significantly based on the scale of the operation and the available space. Some common grow house dimensions include:

  • Small-scale: Converted closet (4’x4′), spare bedroom or basement (~100-300 sq ft)
  • Medium-scale: Detached garage or small house (~500-1000 sq ft)
  • Large-scale: Warehouse, barn or multi unit dwelling (~1000+ sq ft)

Larger facilities enable cultivators to maximize plant yields and produce high volumes but also increase operational costs and risks of detection.

Grow house sizes are often limited by electrical capacity to power grow lights, fans, dehumidifiers etc. Having insufficient space also leads to problems like mold, pests and plant stress from overcrowding.

How do you Set Up a Grow House?

Setting up a proper grow house requires careful planning and preparation. Here are the key steps:

  1. Choose a Location: Find a secure, discreet space with adequate power, ventilation potential and accessibility.

  3. Set Up Growing Area: Construct benches, tables or racks to hold plants. Install grow lights, ballasts and timer controls.
  4. Install Climate Control: Add A/C, dehumidifiers, fans, CO2 generators and monitoring equipment.
  5. Add Growing Medium: Purchase soil or set up hydroponic system with reservoirs and nutrient delivery.
  6. Plant and Cultivate: Germinate seeds or introduce clones, add supports, trim/train plants and tend daily.
  7. Harvest and Process: Flush plants, harvest buds, trim, dry, cure and prepare for distribution.

Maintaining ideal environmental conditions and following proper procedures is crucial for healthy plants and quality product.

How to Use CO2 in a Grow Room?

Increasing CO2 levels is one of the most effective ways to boost plant growth and yields in an indoor grow room. Here are some tips on using CO2 safely:

  • Determine CO2 Level: Typical outdoor levels are around 400-500 ppm. Grow rooms should be 1200-1500 ppm.
  • CO2 Generation: Use CO2 tanks, generators burning natural gas/propane or CO2 burners.
  • Proper Ventilation: Never run CO2 without adequate air exchange and exhaust fans running.
  • Monitor Levels: Use a quality CO2 monitor/controller to avoid excessively high levels.
  • Air Circulation: Install oscillating fans to evenly distribute CO2 throughout canopy.
  • Lighting Schedule: Only enrich with CO2 when lights are on and plants can absorb it.
  • Safety Checks: Install CO2 sensors/alarms and avoid entry if very high levels are detected.

Following best practices allows growers to take full advantage of CO2 enrichment while avoiding health risks.

How to Seal a Grow Room?

How to seal a grow room?

Properly sealing a grow room is essential for containing odors, maintaining ideal environmental conditions, and avoiding detection. Here are some sealing tips:

  • Seal All Openings: Use caulk, spray foam, weatherstripping to close gaps around doors, windows, outlets etc.
  • Install Vapor Barrier: Use polyethylene plastic sheeting rated for vapor/moisture control.
  • Add a Door Sweep: Use high quality door sweeps at base of entries to block light and odors.
  • Seal Ductwork: Seal all ducting connections with aluminum foil tape rated for grow rooms.
  • Hang Pandan Curtains: Install overlapping poly curtains at entries to prevent air transfer.
  • Maintain Negative Pressure: Exhaust more air than you intake to pull odors towards filters.
  • Use Carbon Filter: Install high quality carbon filter on exhaust to scrub odors.

Taking the time to thoroughly seal and contain the environment ensures your grow stays discreet.

Can I Grow Indoors?

Yes, it is possible to successfully grow cannabis plants indoors as long as you can provide the necessary environmental conditions found in nature:

  • Lighting: Grow lights replicating the sun’s light spectrum and intensity are a must.
  • Temperature: Ideal temps are 70-85°F when lights are on, cooler at night.
  • Humidity: 50-70% humidity range during vegetation, lower for flowering.
  • Air Circulation: Fans or oscillating air movement prevents mold, strengthens stems.

What Size Grow Tent for 1 Plant?

The minimum recommended size for growing just one plant in a grow tent is a 2×2 foot tent. This gives enough root and vertical space for one modest sized plant.

However, many growers opt for slightly larger tents to allow more room:

  • 2.5×2.5ft Tent: Enough for one plant to be trained and topped
  • 3x3ft Tent: Ideal for one larger plant, some training
  • 4x4ft Tent: Very spacious for one plant, allows major training

The bigger the tent, the more you can manipulate plant size through training techniques like topping, fimming, lollipopping etc. Larger tents also give you more flexibility with lighting footprints.

Just be sure your tent has the proper height clearance. Most 2-4ft tents are 5-7ft tall but heights vary by model. Your plant’s final size depends on the strain too.

What is a Grow Tent?

A grow tent is a self contained indoor gardening facility made from a light-proof, reflective fabric. It creates an optimum growing environment for plants.

Some key features of grow tents include:

  • Lighttight fabric with reflective interior coating to maximize light efficiency
  • Reinforced plastic corners and solid metallic poles/frames for structure
  • Multiple intake and exhaust ports/vents for air exchange and filter access
  • Removable ceiling vents/filters to allow equipment and ducting pass-through
  • View windows to check on plants without disturbing the environment
  • Tool pockets and adjustable hanging rods/bars for lights and accessories

Quality grow tents allow full control over light cycles, temperature, humidity, ventilation and CO2 levels to replicate ideal conditions year round. Their portability makes them easy to move or disassemble.


What’s the Ideal Temperature for an Indoor Grow Room?

The ideal temperature range is 70-85°F when lights are on and around 58-70°F when lights are off.
