Build up a grow room, and keep it safe with total block film
Total block solution, 250um good quality film, complete block
Description
Used in growing areas - this is waterproof poly film that is black on one side and white on the other. Panda film works well as a reflective film (reflects 90% of the light back to the growing area) or as a room partition. This is a very heavy duty film at a thickness of 8.6mil - 9.8mil.
With hydroponics, the more light your plants get, the more they yield. Hydro Film is double sided with a black side for facing to the outside to block out all light, and a white side to face towards the plants to maximise the reflections.
