The base is made with tin tubing and i used wire hangers for the aches! drilled holes in the tuning and then wrapped it with Clear plastic wrap!!Duct tape here and there!! FREEE!!!
So i Saved myself 2.50 ^^^^ hahaha
i use something similar to get my seeds from paper towel germination to little seedling... I also used just wire to create a dome and cling plastic wrap as it keeps the warmth and moisture in extremely well... much better than the seed germination boxes that you can buy.. sometimes the cheapest and easy to make items work better than the expensive stuff...
