GH floor: plastic or landscape fabric
Comments (16)I agree with laserfan. You don't want to be tripping over either material. Crushed stones alone has worked in my benchtop greenhouse for 16 years. For Greenhouses that you plant into the soil I use black plastic over hand laid driptape and cover the entire surface area, laying boards for walking on and to secure the plastic sheets. Fabric would cost 3-4 times as much. since there is minimal surface water wit drip tape watering I never worry about drainage. But if you do have a drainage problem then you will soon have a muddy and uneven floor without a stone (or concrete) base. I also think plastic provides a better barrier against soil borne pathogens being blown onto plant leaves. For that main reason all of my plastic, including drip tape is replaced each year. If you can't sterilize it and you can't burry it then you should replace it. Otherwise you are developing a breeding ground for all sorts of pests....See MoreGH floor insulation info for maryhm

Comments (13)It's a little hard to see here, but I used 1/2 to 3/4 crushed rock. I would have LOVED to pour a slab with a big fat drain in the middle but the crushed rock only cost about $50 for 3 yards. It's crushed river rock, so there is a lot of round edges. If you get crushed quarry rock it is much better. NO FINES. OLD picture from January I think. I'm eating the peas now :) It stays put very well while walking and moving things around. big enough drainage to hose soil spills down the cracks.

Comments (4)greenhouser2,thank you for your response,I never thought about screwing the bubble wrap down. we used the self tapping screws to hold the panel in place on the GH after a nice windstorm blew some of the panels a block away and that was after buying extra clips from Charleys GH supplies. The swimming pool cover we used was 12 mil crystal clear w/bubbles in it.We were thinking of wrapping the GH from the 12ft. side from the ground over the top to the ground side on the other side and removing the bubble wrap from the ceiling. That would make the swimming pool cover double on the outside. My GH door faces the south, so it gets a lot of light. Mike, you asked what the advantages of bubble wrap over 6mil plastic is that the bubble wrap has air pocket that heat up in the day time and stays warmer longer,plus I think the BW is thicker than 6mil. and the light was just as strong....See Morecalliope
