It can go directly in the garden if it is just poop, but rabbits tend to poop and pee in the same place hence some letting it 'cool'. Unless you are using a ton of it I wouldn't worry too much about it.

I used to garden in Kuwait but winters there are a fair bit cooler and longer than in Dubai. I didn't grow beets or carrots but I did grow other cool season crops/flowers like lettuce, potatoes and pansies. I seeded those in late October for a Jan-Mar harvest. Tomatoes and peppers were seeded in late September for a Jan-May harvest. But because spring arrives earlier and hotter in Dubai, you might have to shift those dates earlier, so they don't mature in the heat. Seedlings can take heat better than mature plants, in the case of these crops. Still, I would wait until October for seeding any cool-season crops. As suggested by others, starting indoors and transplanting is a good idea - just make sure you harden them off really well. Water very frequently when the weather is hot - deep, infrequent watering does not work there because of the sandy soil and high soil temperatures. Always do a moderate watering in the afternoon to cool off the soil surface a little, and a more substantial watering every morning. If you're planting in the ground, amend with lots of compost. Otherwise, soil pH might be a bit on the high side for tomatoes and peppers.

Your ground water is not quite cold enough for passive cooling. It should not rise above 46ðF ~ 47ðF. You will also have to remove the humidity from the fan coils and have enough water flow from your well for both cooling and domestic water usage. How do you plan to responsibly dispose of the water used for cooling? That could be up to about 600gph. You would not likely return the water to the same well as the temperature will may rise above the level of viability. SR

I am good with either as long as they don't sleep too hot. I was set to buy LL Bean percale which have been highly recommended around the web but the most recent reviews aren't all that great. I live in the UK currently and will only be home for a few days and won't have time to run around checking out every b+m store's selection. Bonus if anyone has a recommendation for a white or gray blanket for a king sized bed that isn't too heavy.
