I am a new grower and I have two questions that I really asked you to give answer.I 'm using grow box whose dimensions are 192x192x192cm perfect closed.I' m planing between 30-50 plants on the surface with 2 HPS lamps from 600w and two fan. Also, I'm using aeroponic system with a sprayer. My questions are:
1. fans have to work constantly all during 18-24 h light period, or in a certain interval, several times a day?
2.sprayers have to work constantly during the light period or several times a day?
I've reviewed tons of films and read lots of books but the answers to my questions not mentioned anywhere.
Much to me if you gave me the answers, because they are two things that really worry me.
thank you very much
Soo... you have just a little more than 6' cubed, two 600 watt hps each covering 3' by 6'. hmmm...... You are going to air cool the lights right? Separate from intake and exhaust.
1) Your co2 eating monsters will require 'fresh air' that has not had the oxygen depleted all day every day. your fan needs to be capable of exchanging the air every 3 to 5 minutes and will require an intake. you can't pull air out of the space with out replacing it. Your intake can be passive, unless smell is an issue and you will be using a carbon filter, then it will need to be active, requiring a fan, and that fan needs to be slightly smaller than the exhaust fan.
2) Sprayers, what are sprayers? Oh, you mean something in some kind of a hydro system using some kind of medium?? The watering schedule is medium dependent. And then it can depend on were they are spraying, top water using drip/sprayers or in an aero system.
I know folks that let their systems run 24/7 and some that run them on timers, it depend on what you are growing in. You will have to provide some more information. VV
