Disappointed in my yield from my last runs and had a few questions. Will cold temps decrease yield much? Also had a ballast take a dump in veg and only had the plants under 2 32w lights(was under a 400w mh before) until a new ballast could come. Also didnt veg to long because I had to move unexpectedly and didnt have a ph meter. So i figured a combo of all these things can def give me a disappointing result, but Im in the process of building a cab for my next project and want to improve. Maybe a small heater or heat mats for temp? Thanks in advance fellow growers and stay safe!
