I am ready to install a 12" exhaust fan to expel the stifling heat from the GH, and I've just strung up shade cloth to cut down on the burning effects of the sun inside. Since I now have a greenhouse, I can control the moisture the collection gets. We can usually expect two brief heat waves in the 90s (33-37C), often with a good deal of humidity. The recent Summers we've experienced are generally very comfortable with a range of roughly low 70s to mid 80s (22-29C) and partly sunny to full sun. In the Summer weather patterns tend to speed up, but not always. It's been like that for about four days, due to a very slow moving low pressure. On the average, what we expect is a late Spring today for example is cloudy, showery and cool (in the mid 40s-27/28C).

Tomorite is the usual brand over here having the ratio NPK: 4-3-8, plus magnesium. However some maintain cacti do want a bit of nitrogen in the growing season. In fact apart from special cactus fertilisers like "Buxbaum's Health Salts" in those days it was the only conventional fertiliser recommended for our plants. Maybe that's not such a problem in hotter climates where there is more sun to harden the growth before the winter. This product meets the requirements of the National Organic Program (US, NOP) for use in organic agriculture, and is approved by OMRI.Īpproved for Organic Use, Fertilizers, Plant Food, Soil EnhancersWe used tomato fertiliser in the UK for cacti and succulents for decades since it was lower in nitrogen, therefore did not produce the soft lush growth that general garden fertilisers did.
