Doing to do both! auto and photos. Well first time for me and. I am planning to start with a biobizz light mix and then translant to all mix. Also doing 2 autos which i am going to use light mix all the way for. Budget is an issue and i have ONE 400 W hid just for the photos. How many photos can i get under a 400 w light with SOME additional side lighting? I am going to convert a nice cupboard and How much Intake should i have? If i used 2 of these Grow Room Hydroponic Extract Air Input Fan In Line Secret Jardin Tent Fan 4" dia | eBay for the Intake in the cupboard and used this http://www.ebay.co.uk/itm/4-Line-Fa...Bottle_Warmers_Coolers_LE&hash=item1c2063be54 for the exhaust would that be sufficient enough for 4 plants in a cupboard? Iv heard they dont last as long but do the same job. I just need reassurance that it wont be a complete fail. Id liek to know if budget carbon filters ( not home made ones ) from actual grow shops which are like 40 dollars do the job? i May get better fan/carbon for the photos but i am planning to do proper budget jobs on the autos and using carbon filters which are like 30 dollars btw i will have 4 photos under a 400 W hid and 4 autos in a seperate cupboardunder a 250 W cfl. Can i add more under these lightings? Also one last question what magnifying glass do i need to see spidermites/pests and what size glass would i need to lok at the resin glands? Thanks!
