Silly Paint is a cannabis strain bred by Cookies. Silly Paint is a cross of Runtz and Melted Sherb. Silly Paint phenotypes go all over the place, but the bud structure tends to lean towards the Runtz. Silly Paint puts on a lot of weight as she reaches maturity, Cookies recommends selecting phenotypes based on finishing time but most phenotypes will take between eight and nine weeks with the occasional ten-weeker in the mix.
