For the greenhouse growers out there...what can I ...

well just lets look whats will come to you. But be prepared for some insects you dont want^^. anf the best is to fight against them with predators, because its no closed envoirement , but semi opened. And yes i agree temperature is a challenge, but you have the big adavatage do have a roof, and a little control about heat, cold and ventilation. I sarted last year in greenhouse and was concerned about the temperatures and the RH. But weed grows under nearly every condition. Ive put them later outside. But my neighbour let them the hole cycle in the greenhouse. His problems e were thrips, mites, and in the late floweringthe humidity. He fought the insects with predatirs that worked bet for it, because sparying does not help... yellowstickers and nematode against thrips. predator mties against russet mites. and ladybug larvae/ladybugs against plantlice/ aphids. Biggetst challenge were lower temps and high th near the end of grow. We gace some airflow and defoilation, but seen alltogether it was successful
