Mine will be smallr, only fitting three clones, as it will be inside the terrarium. Yours can truly accomodate a lot more clones. When you have the space, it is sure better. I don't need more than three at a time, though. Smaller space needs smaller air pump as well. So less noise..
My air pump is a piezo electric one. Completely silent. And I mean completely! All the other air pumps I have tried make noise, even the ultra silent ones. Not useful in a stealth op... But the piezoelectric pumps are weaker ones, so they limit the size possible for a cloner. Your size would need two or three. Well worth it anyways, because of the lack of noise. All I can hear is the sounds of the bubbles. My prototype cloner has the bottom of its lid insulated with sponge, and the whole bubbler is buried in the soil of the terrarium, so it makes no sound what so ever. I will finish it this week and hopefully the Candida clones will root. I hope the water will not be too hot from the tub being in soil. Hope to not need a powerhead as well, due to the small size of the bubbler..
