Have just bought a Gardman GROWHOUSE. It is made from a soft wood and the company recommends it is treated with a preservative that is harmless to plants. I have used Cuprinol in the past but do not know if it safe for plants, and don't have any left anyway. I presume the product must not give off fumes, so when plants are inside with the door shut, they will not come to any harm. Advice much appreciated please.
