I have decided to try and get an early harvest this year with some autoflowering strains. I was wondering if anyone knows how early I could put seedlings outside with soda bottle greenhouses? I normally plant in the end of April.
march april depending on where u live but a soda bottle green house isnt all its cracked up to be lol you may need to keep to top open to adjust humidity which would defeat the purpose of having a soda bottle green house id suggest building a box with a propable window if u paint the inside black you should be good to plant in it already if not then the next couple of weeks and you can keep it open a crack to regulate the humidity and temp google diy greenhouse to get some more ideas
