bass guy Posted November 20, 2007 Report Share Posted November 20, 2007 My plants look dreadful. My tank for lowlanders stays over 70F with over 65-70% humidity. When I left a space in the top, humidity would drop. I FINALLY got a fan in there, but I wonder if it is too powerful. It is a 40 gallon tank...how large of a fan would you folks recommend? Should it be on all of the time or is that too much? I watch the rafflesiana fluttering in the wind and think that this can't be good for it. Please describe your methods of air circulation. I'm sick of LFS getting algae (or whatever the green crud is) and the plants looking so bad. How much of a gap is ideal in the lid for circulation?

Rob-Rah Posted November 20, 2007 Report Share Posted November 20, 2007 Umm. For fools like me, can you say the dimensions of the tank rather than te gallonage? I can't visualise how big it is.... Quote Link to comment Share on other sites More sharing options...
bass guy Posted November 21, 2007 Author Report Share Posted November 21, 2007 4 feet long by 1 foot (or close to it) deep by...ah, something else high. Foot and a half maybe. Quote Link to comment Share on other sites More sharing options...
Rob-Rah Posted November 21, 2007 Report Share Posted November 21, 2007 (edited) Three of the small fans from computers should suffice, running them at approx 7V from a variable transformer. Space them equally along the tank and angled appropriately for maximum variety. If the tank is very crammed with plants in every spare bit of airspace that will hinder air movement though. What sort of fan are you using at the moment? Cheers. Edited November 21, 2007 by Rob-Rah Quote Link to comment Share on other sites More sharing options...
venusflytrapman Posted November 21, 2007 Report Share Posted November 21, 2007 You could adjust it to blow over the roots suface of the pot, then the plant won't be suffering. Quote Link to comment Share on other sites More sharing options...
bucky78 Posted January 14, 2008 Report Share Posted January 14, 2008 So I need to add a question to this thread. For those growing Neps in a terrarium or aquarium, do you leave the fans on 24/7 or do you have them on a timer like to run while the lights are on?
