Deep steaming is a special surface steaming process that takes place under the sheet. You will need an additional vacuum device for deep steaming. This device can be either mobile or rigidly installed in the greenhouse floor. I) Mobile vacuum system (at 50cm steaming depth) For this purpose, you have to lay pipes for air suction and install a special fan above the ground. It does not require much work or expense. At the pipe ends, heat-resistant hoses are burrowed into the soil at the desired depth. Through this steaming method, a uniform negative pressure is generated in the soil and the steam is sucked into the depths. II) Rigidly-laid drainage pipes (up to 80 cm steaming depth) In this method, drainage pipes are rigidly laid under the ground and connected to an extra exhaust station. There are professional firms who specialise in installing such systems. Attention must be paid to the fact that, in this case, deep steaming will cause a strong increase in energy consumption. Depending on the steaming depth and the soil properties, this steaming method will very likely require more than 3 litres of heating oil per square metre. Know how! Tips and tricks In the case of a mobile exhaust system, a central suction line consisting of galvanised quick-coupling pipes is connected to the special fan by 1.5m spacing. The hose ends are inserted to the desired steaming depth with a special inserting stick. Suction pipes can be laid easily and quickly. The same applies to their connection to the exhaust turbine.
