New Greenhouse Questions

[Jane Wesley Brooks]

H there,

I have a new greenhouse that I am trying to get going with the swamp cooler, shade cover, water filtration system, fan, etc and I am struggling with a few things:

1) How do I drape a shade cloth (Aluminet) over the top of the GH and not prevent the vent from being able to open as needed?

2)  I was told not to try and get more than a single bench layer as stacked benches would not allow enough light for the plants on the second layer...thoughts?

3) How do you best control snails and slugs from getting inside the GH?  I was told to use diatamateous earth on the interior perimeter and at all joinings of the GH panels to the aluminum frame..that seems like a full time job...suggestions?

4) I have a water filtration system installed but the water pressure is now non-existent!  It is called a "Little Boy" and was highly recommended by a 40 year orchid grower/enthusiast?  Suggestions?

I appreciate your help with my inquiry and any other suggestions you may have....

Thank you!
