hi, I’m setting up my first tank and in preparation for lockdown I purchased some plants ready for when they can go into the tank and I’m concerned about how I’m storing them. Currently I have them in s black bucket with treated tap water adding some liquid fertiliser, yesterday I put the bucket in the sun and the water got quite warm then into my garage overnight, temp of water dropped quite a bit. So some fluctuation of water temp, I don’t have a thermometer yet! Would it be better to leave in one location? I do have a standard desk lamp I can use rather putting in sun light? Any help gratefully accepted! Cheers
