As we discussed in a topic several weeks ago, normal wine fridge behavior is to have a significant time constant in temperature control. Hence fairly rapid relay state changes would seem to be abnormal. Sound level is a different issue perhaps related to price; the very expensive and quiet units like Perlick and SZ probably use noiseless solid-state relays. kas

Sour Orange or Bitter Orange or Seville Orange is Citrus x aurantium (subsp. amara according to some, amara meaning bitter). They are the same citrus and the extent to which the different varieties may differ is similar to the difference between Washington and Valencia sweet oranges for example. Different cultivars of course exist but they are the same citrus tree. All of them produce bitter-sour round fruit, with more or less coarse rind which becomes deep orange in maturity (at least when grown in a med type climate). and pale yellow--greenish pulp. The leaves have a pronounced elongated petiole and the tree usually carries some long thorns on the more vigorous shoots. Bitterness is extremely pronounced so the name 'sour orange' is kind of a misnomer. Yes they are sour but most of all they are bitter. The fruit is inedible when raw regardless of the level of maturity. They have a distinctive perfume both in the rind and in the leaves which cannot be confused for other citrus. This is what has been used for rootstock for centuries and for English 'Orange' Marmalade. I don't know what might be called sour orange in the Americas but if it is not what I have described it is not Sour Orange. Not every sour tasting 'orange' is a Sour Orange. The name 'Seville Orange' is of course an old name the English importers gave it a long time ago and may now be a legally protected name. But this is just a commercial issue. In Greek the name for the tree 'nerantzia' has the same roots as naranja and aurantium. The trees were introduced in the Med region before sweet orange was. Bergamot is really a different citrus, most probably a cross between SO and a limetta (which gave it its distinctive flavour). In the East Med we grow sour limettas which carry the same perfume as Bergamot orange but look like lemons or citron.

Timi, one of the names will be, I think, Rhipsalis, but it could now be known by another name (things are always getting reclassified), like Hatiora. It's a jungle cactus, growing in the crotches of trees/limbs of trees, in leaf litter and fauna droppings. It needs excellent drainage.

Steve could you come up with something easier. It looks like one of your tricks, a four leaf clover growing on one of your trees, wrong? Sorry, I know little about citrus rootstocks.
