Step 5: Reuse of box bottoms

Depending on the box used, the 2 bottoms may be reused for moving potted plants. For this, the optional 4 small rotatable wheels are applied to the bottoms, with the use of the 8 additional woodscrews.
<p>Excellent contruction! Cool too!</p>
The comment that pressure treated lumber is toxic is not true.
Please be very careful about the type of wood you use! Never use pressure treated wood to construct anything that you will be growing food in- it leaches toxic chemicals into your food...<br>
That's something called a cold frame. They've been around for years.
&nbsp;Hopefully this isn't a stupid question, but, what type of glass is that. I would guess the darkness of it pulls in heat? Correct?
Well if it was darker it would convert more light energy to heat energy, therefore increasing efficiency. Using the principal of hot always goes to cold, the heat from the cold glass will transfer into the air.<br />
you could use old style storm windows or wooden window shashs for the glass. They might be a bit heavier, but safer having a covered edge.
This is exactly what I was looking for! Thank you very much for putting it together.
