The first thing to do is determine where in your yard you have space that is also level.  Most greenhouse kits will need to be built on level ground.  Then determine how big your green house will be; do you prefer an 8 x 8 or maybe a 12 x 16?  You will need to know that in order to measure out the foundation for your home greenhouse.

Drive a stake in the ground at one corner and measure out your foundation from corner to corner (remember the size greenhouse you are getting) and stake the other three corners and pull the string tight revealing the exact size you will need for your foundation.  Always take a tape measure out and double check the measurements.

Lay out the newspaper (about 6 to 7 layers) to cover the entire area.  You can wet it in a bucket or have a water source handy to spray the paper to stay down as you lay it out.  Once you have it laid out it’s up to you what material you would like to have for a quick foundation.  You can choose an organic material such as mulch or a rock or gravel material.

The main things you will need to watch is to make sure the newspaper is totally smothered and can still get moisture.  You can also use newspapers underneath several kinds of flooring to keep your greenhouse floor nice and clear of weeds and unwanted grasses.

There are a lot of different coverings you can use to replace the old skin, from different plastics to glass.  They come in all shapes and sizes and are shipped from UPS to freight.  You can get one layer or double walled, custom to one size fits all and all you have to do is find the one that fit’s your frame and your budget.

If that sounds too hard, you can cover it again with cheap plastic and replaced it again next year.  It will tear, sweat, leak and mildew just like it always does.  You most likely pay more to cover that frame every year than it would be for a long term solution.  Some guaranteed up to 8 years.  Of course, you may like covering that thing every year.
