The 100 ml spray bottle, convenient and practical, is essential in the initial stage of seed growth. It is used to moisten the grid before and after sowing, the substrate after sowing, the lid before the blackout phase, and the seeds, 1-2 times a day until the roots have reached the water. In the case of cultivation with substrate, if it remains consistently moist, there is no need to moisten once the seeds have germinated.
