New Grower Wanting to get started! 4x4 grow tent

[Bigandy]

Hello AFN! I currently am in the execution phase of gathering all materials needed and ordering seeds. I've chosen all Dutch Passion seeds for a first time grow. Want to do 6 total. Is that too many for a 4x4 tent under a California Lightworks 330 LED. CHose AUTOmazar. Auto think diff. auto blueberry. autoxtreme. i know some of these are larger so am a bit concerned on space.

Big questions i have right now are about nutrients and carbon filter. Also looking for any tips or recommendations anyone may have regarding seed selection i've made.

What size carbon filter and brand is best? most trusted? also would like the quietest fans to match up with it so a recommendation there would be great too!

I am a total newby first time grower here with no other resource/help then the good old internet and this forum.

Nutrients ?? is there some sort of a guide out there for choosing what to use and how to use them. i wanna do everything right and know there is a bit to it.

Any help or idea or points in the right direction would be awesome and thanks in advance!

i can tell you what nutes i use AN and your extraction depends upon the grow area and which and how many lights you have, you should use the same size carbon filter as your extractor fan

Below are two ways you can work out the size of extractor fans you will need in your grow room.

1. This method is based on the volume of the grow area and is perfectly suitable for small grow rooms.

First calculate the size of the room in cubic meters (m3): Length x Width x Height in meters = size of room in cubic meters.

Then multiply the total m3 by 25 to give you the air exchange needed in one hour.

Add 30% to this figure to allow for the inefficiency created by using carbon filters and lengths of ducting and the figure you will have is the air exchange rate needed in m3/hour for your grow area.

Because all extractors are sold with a m3/hour air exchange rate, it is a simple matter to select the correct size fan(s) you will need. For example, if you have calculated the air exchange rate needed is 450m3/hour then this could be achieved by using one exhaust fan rated to 450m3/hour or by using two fans, one for input and one for exhaust that together total this amount. If you use two fans (recommended) make sure that the exhaust fan is approximately 70% larger than the input fan.

2. This formula is used by commercial growers and is based on the number of lights used. This is recommended for medium to large sized grow rooms and guarantees the control of temperature regardless of the number of lights being used.

Extraction:

Take into account at least 200m3 of exhaust for each 400w lamp
Take into account at least 300m3 of exhaust for each 600w lamp

Add approximately 30% more exhaust to this to allow for the inefficiency created by carbon filters and lengths of ducting.

Intake:

Intake should be approximately one third to one half of the volume of the exhaust. (If your extractor is 1000m3 per hour or less, use approximately one third of its volume for input. if your extractor is over 1000m3 per hour, use one half of its volume as input)
