My 6-8ft will be placed on wood which will be sitting on a cement slab. GH will be in a sheltered area to a extent next to the house and will only get wind from one side really. We are renting are home so can't ruin anything,so looking for a quick and easy way to anchor the GH down. What are something's I can find at Lowes to keep the GH anchored? I have not removed the GH from the box yet. So not sure if I could just get longer,thicker bolts,drill holes through the wood frame and into the concert deep enough to keep it still? We are coastal so we get some windy times during hurricane season,that's why it's being placed in a sheltered area. Thanks.
