Green-Qube utilises brand new cutting-edge technology which dramatically eradicates light leakage with its new StitchBLOK® technology. This increases light-proofing by 78%, meaning Green-Qube tents at now 99% light tight.
StitchBLOK® is found on all ports within all our Green-Qube, Roof-Qube and LED-Qube grow tents and ensures a total block of all light.
StitchBLOK® employs Tritec® foam which works in a similar way to memory foam. Around all vents and ports, Tritec® foam is imbedded between the inner and outer shell. Once the stitching process is completed, the foam re-inflates so that all stitch holes are totally sealed and no light can escape. This offers complete light blocking on all ports.
