Ok here it goes my first post being a new member again after 4 years away.(not sure why in the world I stayed away).
I bought portable green house off Ebay and I would like to know what everyone thinks of these.
Are they a waste of time? I was starting seeds inside but my three year old loves dirt and would destroy them every time. The greenhouse is 8' long by 6' wide by 7' tall.
Also was thinking about a floor for it and was wondering what everyone thought would be best. I was thinking about getting a piece of outdoor carpet and using it what do you think?
I am posting a picture.Also it doesn't provide for ventilation. Will fans be all I need or will I need to maybe cut some flaps? I know this is several questions sorry if I went overboard.
Thanks for any help you can provide.
God bless, Keith
