tomatillos and hot peppars

I am curious about other people's experience with growing in common home gardens the vegetables indicated above. I am near Uppsala, Sweden, so conditions are not favorable.
I am hoping for tips on the use of bone and other sources of Ca2+, for instance. My location is former tributary to the Baltic Sea, and is basically entirely clay. The pH is a bit acidic, around 5.5 to 6.0, as I am told from others.
If I treat the soil, can/should I treat this the same as for hot peppars (Habanero, serano, jalapeno, etc), or do these need something totally different?
For fertilizers, we have good access to horse maneur in hay, which seems to work with other unrelated plants, onions, garlic, pumpkins, etc.
I am mostly done building a greenhouse, but certainly welcome pointers about optimal design.
Suitable web links, books, and your comments will be much appreciated....

You need sandy soil and hot days for these to really get going. I have had very good crops of both, especially Habanero Peppers here in the Mojave Desert of California, USA.

Free draining soil. Lots of sun and heat. Not too much nitrogen or you wont get many fruit Also dont forget for tomatillo's, grow at least two. One will not fertilize itself!! A google search should give you a ton of info.

Google: Less than you would think. I did find this group. Thanks for your thoughts. The need for multiple plants is new to me, but I planned for many plants, just in case. I think I am going to manage well with an orange variant and another rather large green variant. I have (had anyway) purple, but these appear to have all died very early during sprouting.
