Homemade humidifier

Do you think this would work for raising humidity in a small closet? My humidity ranges from 11% to 20%.

well it may work to raise the humidity, but your DAMN sure want more then 20% for vegging ya should go with 50-70% and flowering 20-50%, interesting concept tho, my humidity level is around a SAD 16% so i need a DIY kit myself, i think i may try that but on a bigger scale, that 1 small spomge pouch wont help that much, mau need as many as 4-10 of those depending on grow room size, ----------------------------420
