How does the strawberry develops?

Here is a picture sequence of how does a strawberry develops from it's flower stage to it's "fruit" stage.
That's right, quotation marks. Strawberries are not fruits. The real fruits are the tiny little seeds arroud it, the achenes, a dry fruit. The strawberry (red part) grows from the receptacle expansion, and can be promoted by some plant hormones like giberelic acid (produced by the achenes). Here are some pics that I took and found interesting.

How to build a little greenhouse.

If you're looking for any tip to build a little greenhouse, you've came to the right place.
Yesterday I was wondering if the tobacco plants would not grow faster in a more appropriate clime, and so, I decided to construct my own little greenhouse.
To do this, I went to Bricomarché, and I bought some "sticks" with 1.5x1.5cm (aprox. 0.06x0.06 inches) and cut them in 40cm long bars (1.58 inches), and some other wooden sticks with 3x1.5cm (0.12x0.06 inches) and cuted them in 60cm long bars (2.36 inches), to do the second picture structure.
Then, to do the door I took 2 old hinges that I had, and placed them in previously marked places with screws. Them made the door with the same stick measures (40cm x 60cm), as in the third pic.
At the end I took some flat pushpins and atached the plastic to the structure, and the end result is on fourth pic.
Note: To unite the sticks I used little nails and some wood glue to give strenght to the greenhouse.
Any doubt or more specific aspect, do not hesitate in contact me.
Thanks for reading.

The seeds keep growing.

This is a normal update destined to someone that is raising tobacco plants and want to compare.
As it was in the begining the egipcian variant is the one with the less germination rate (until now).
In the other hand, the Burley, Virginia gold and the Oriental are growing pretty well.
These are some fotos to you compare and comprove.
