Growing weed in a greenhouse


 Growing weed in a greenhouse is an easy and cheap way to grow your own cannabis. The greenhouse protects your cannabis plants from the worst of the rain, wind and cold. This allows your cannabis plants to grow faster than they might outside of the greenhouse. A greenhouse also minimises the impact of the poor early season weather, allowing your cannabis plants to grow faster. This allows larger harvests. One final bonus of greenhouse growing is that the mature plants are protected from cooler, damp weather at the end of the season. This allows the plants to mature and swell under the protection of the greenhouse, safe from the potentially damaging autumn weather.

Preparing your greenhouse for growing cannabis.

A small amount of preparation in your greenhouse will allow you to get some extra special results. One of the most useful tips is to improve the soil quality. Some growers regularly replace the greenhouse soil, adding high quality compost. This can be home-made or bought from a garden centre. Many growers will add soil improvers such as bat guano, well rotted manure, worm castings etc. These will act as slow-release fertilisers that give extra nutrition to your plants, which should allow healthier plants with better quality harvests. At the start of each growing season, the experienced greenhouse grower also spend a day cleaning the greenhouse. This involves cleaning all the glass, ensuring that the greenhouse is clean and in good condition for the coming season.

Problems growing cannabis in a greenhouse.

High temperatures in the middle of summer are one of the potential issues for greenhouse growers. When the sun appears, temperatures can quickly reach 30ºC or above. For some varieties this can cause the plants to wilt. There are several possible solutions to this issue. Many growers use automatic ventilation panels that open in hot weather. Other growers use a white opaque greenhouse paint, this gives the greenhouse a white exterior and the greenhouse reflects more of the light and heat, making the interior much cooler. One added advantage of using greenhouse paint is that it gives instant visual protection for your plants, no-one can see whats inside your greenhouse. Some greenhouse cannabis growers like to open the greenhouse doors on the hottest days, this allows a cooling breeze to flow through the greenhouse. In hot weather your cannabis plants may/will need extra water - a hose pipe is a great way to quickly replenish the water levels in your greenhouse soil.

Growing autoflower seeds in a greenhouse.

It’s easy to grow autoflower seeds in a greenhouse. Autoflower seeds tend to grow into plants which are around a metre tall, this lower hight be more convenient for some people. Feminized seeds can sometimes reach 2-3 metres tall, which can cause problems in small/medium greenhouses.
