Hey man word of warning, I have the same greenhouse and same little plastic chips falling off.... thought it was under control but one light rain last night and a friggin third of the entire roof disintegrated and stuck to my plants. Cut them all down as a major loss. If you have rain in the forecast be REALLY careful man. Fuck that cheap ass PE mesh! Looking to build a replacement greeny now about the same dimensions... Not trying to bum you out just giving you fair warning. Your plants look amazing and I've been following along. Yours are 6' and mine are a bunch of 1" stumps.
