Easy Hothouse to Propagate Plants




I have made several of the soda bottle hot houses but have found that they take up a lot of space and when the seeds get to the edge they start to die so I was thinking about how to make a hot house cheaply.

I realized that after a recent move I had several of these plastic bins that were just being stored away in the attic and I thought maybe it would work as a larger hothouse.

Step 1: Materials Needed

I went to a home improvement store and got one of the light diffusers for a fluorescent light fixture and started to cut it up into sections that fit the lid of the container. I use this so that the pots don’t sit in the water and I put water in that area so that it creates a very humid environment.

I have also done this with smaller containers but am finding I am enjoying the larger containers

Step 2: Closeup

This seems to keep the seeds growing well and become well established so that I can eventually remove the bottom area of the bin and harden them off and get them ready to transplant.

Step 3: Putting It All Together

I was using this method to grow plumeria seeds and the methods I had were at best marginal on the success rate but this new method has become very successful in growing the seeds and not over watering them.

Plumerias are a tropical plant for those of you who don’t know what they are so they thrive in this environment. I have tried other seeds and they seem to do well in the hot house but I have to take them out sooner than the plumerias.

I use a potting method for the seeds similar to the ones described in this site but I purchased an item from Burpee seed catalog that is really a large wood cylinder that you wrap a 10 by 3.5 inch piece of newspaper around and press into the base to make a pot.

As you see I put the top of the container as the base and put the clear container over it.

I put water in the area of the lid so that it doesn't go over the diffuser and keeps a himid environment. (see humidity on the sides of this container.)

    That looks great. Do you use this indoors or outdoor? Also a strange group of "related" instructables come up, which seem quite unrelated. Maybe you can add plants, propagate, gardening etc. to the keyword/tags. It would be nice if instructables had a gardening category too.

    Do you have any trouble with fungus? Full sized green houses have windows and/or fans to keep the air moving. The air movement is needed to minimize damage from disease. Also you may have noticed this website can't handle special characters like so called smart quotes. If you edit your text inside the Instructables toolkit, it will clean it up.

    I just pasted the text into the sections I didn't do smart quotes As for fungus no I tend to open them up once they begin to grow to keep the air flowing and I put the lid on in the evening to trap some of the warm air so the seedlings don't get damaged so far no fugus but then I do clean it up when I have a batch growing well and ready to transplant
