Tallinn, Estonia: Climate, Global Warming, and Daylight Charts and Data

are you planning an outdoor grow well now is the time to find your grow spot and clear it of weeds and over growth. making sure it is south facing (as i gave some1, 19 plants and put them on the north side of a hill, :wtf: very small plants.) then turn the soil and not sure on the soil conditions, could give it a dusting of lime letting the rain wash it in.
then in the early spring go back out, add some cow dung or what ever you have handy mix it in well with the soil.
then you could plant out some plants in stages end of april ,end of may, and end of june.
this should give ya 3 good batches but with the light not getting shorter than 13hours till september looks like ya would have harvest in 1st week of november.
if ya had a green house this would help against early morning frost
i know there are some early flower plants out there that start to flower when it gets less than 15 hours. most seed banks should have an early flower type just look round them as it depends on what ya want, stoned wise
just dont tell any1 you are growing!
but get in touch with more info
you will love growing your own :thumbsup:
there is alot of help in the growing sections
