I know it’s simple. But getting things level or straight has always been hard for me.
I did get a laser level for hanging pictures, and I think that is relatively idiot proof. However you have to get a good stand for it - holding it in your hand in a wall just gives wobbly lines.
I used a line level to get the paver supports level, then a 48" (121.92 cm) level on the beams to make adjustments. Still some minor spots to shore up but the beams being level is the main thing as that is what the greenhouse will attach to.
