I have a Grow Tent where I grow my onions and leeks , in fact you can grow whatever you like in them. Our grow tents available here have the following…
- Fast Assembly
- Fully light proof material
- Tough Stitching
- Heavy duty light proof zip
- Double sealed cuffs on inlets and outlets
- Fully lined with highly reflective Mylar
- Heavy duty hanging points for lighting and extraction
- Adjustable velcro sealed window
- Compact carry car
I use these myself , see below ….
They are excellent when used with the TS Lights, all you then need is a small fan heater to maintain about 18c , a CO2 bottle with controller and a extraction fan to change the air every so often.
Many growers fail to recognize the importance of Carbon Dioxide in their growroom. most plants grow faster and larger with enhanced CO2 levels because of more efficient photosynthesis and a reduction in water loss. There are also many other benefits for plants, among them greater resistance to temperature extremes and other forms of stress, better growth at low light intensities, improved root/top ratios & less injury from air pollutants.
Photosynthesis is the term used to describe the process by which plants combine CO2 molecules with water molecules to form complex sugars, there is a resultant spare oxygen atom which is released back into the air, the sugars being further processed by the plant to form natural polymers for growth. The ambient level of CO2 in air is 300-400 PPM, fast growing plants in your growroom or glasshouse can use all the available CO2 in less than an hour slowing photosynthesis and therefore growth to a virtual halt.
It can be seen that the rate at which plants are able to grow is relative to the availability of photosynthesized complex sugars. Raising the ambient CO2 level in your growroom causes more sugars to be produced allowing the plant to grow bigger and faster. The optimum level of CO2 for plant growth is generally accepted at 1200-1600 PPM, plants grown in this environment can grow up to 40% faster thus shortening crop times and increasing yields. This is of course assuming no other limiting factors such as lack of available light etc. Peter Glazebrook used CO2 when he grew is world record bulb in 2011 . Its best applied in the Grow Tent via a cylinder and controller , when you use it in the tunnel or greenhouse you can use either the cylinder or a gas burner CO2 generator, whichever your plants will do much better. Many commercial grows use added CO2 in their growing areas.
Here is an image of my CO2 controller ….
I also use a Systemair RVK fan set on the top of my Grow Tent this is set to come on for just 1 minute every 1/2 hour , it has an intake duct attached from the bottom of the fan to one of the socks on the bottom of the Grow Tent where it pulls in fresh air, I also leave another sock open so the fan can suck fresh air in, this air is then circulated around my grow tent and the old air extracted out.
Heres an image of my fan….
And the ducting…
