Hi all,
I am considering my next project using a 3mx3m tent but have questions re lighting and ventilation/circulation.
3x3 gives us 9m2... so, is it possible to have 9 600w, 1 light per m2? 4 plants under each light.
I have read that 6 lights is enough, but I dont know if that will deliver the same light intensity, which is important to me for reaching expected yield.
Someone mentioned it could be done as long as the was adequate ventilation extracting the heat? Which brings me onto my next question;
As generally grow tents are not air tight, is an intake fan always necessay?
On a groom I built recently we used a 12in box fan to draw in fresh through x2 8in ducting either side of the room at floor level, and as the room was air tight an intake fan wasn't needed.
What are the calcs for a 3mx3mx2m tent re filter/extractor fan size? And has anyone got any recommendations for a super quiet stealth like fan(s). On another project we put carboard boxes over them which worked surprisingly well, but want something a bit more professional this time round.
Thanks
