I'm waiting for the rest of my plants to arrive. The first amount that arrived today, is now in a clear plastic tub of clean dechlorinated water. I removed all the packaging, rock wool, ceramic rings etc from these plants, removed dead lives and then used some plant weights to keep them submerged in the water. There is no direct light on them or heater in the tub with them.
I do have a small heater, that came as a set with a 105L tank but I've been worried that a heater in such a small space among the plants would damage them ( or melt the plastic maybe). It's not one of the heaters that can keep the water a certain temperature. (I mean one that would turn itself off when it is too hot, and when the temperature drops it would start heating.)
There is about 7.5L of water in the tub, and it's currently 19.3 degrees Celsius.
I expect them to be planted in the tank before Sunday, if there are no delays for the other plants in customs.
How long will they be okay, do I need to heat the tub to avoid any negative effects?
