I've decide to compartmentalize my light from the rest of the box with a piece of glass, and give it some independant ventilation. Now I know the glass should be tempered (why though?), anything else I should know about glass before I go and get a piece. How would a piece of glass effect the...

How do I go about getting a custom piece of tempered glass?

Dimensions are about 3X4X5. Frame is 2by2s the walls are osb boards. 400 watt ballast with a 430 son agro bulb. 4 inch elicent inline fan for exhaust attached to a DIY carbon filter. Air comes in through holes in the the floor, its kinda complicated, the floor is raised about 2 inches off the...

My box is done... but I ran into a problem. My 175 dollar inline fan doesnt move enough air to keep my box cool enough, it gets all the way up to 92F with my 430 son agro bulb. So, after all this time and money I invested into this project, this was somewhat devastating. I took a break, my...

Well, all my plants are on the brink of death, but I think I figured out why. Whenever I watered then I did so with a mister, and only a couple mist to keep the soil damp. As a tester I gave a plant about 5 times more water than I usually do, and came back in about an hour, and stuck my finger...

Here are the specs for the grow Soil Mix: 4 parts top soil (best I could find) 1 part Schultz Potting Soil (0.012-0.18-0.012)(Has some perlite in it) 2 parts Vermeculite A small handful of Dolimite Lime Lighting: Two 23 watt CFLs, one 43 watt CFL, about 1ft above the pots. Sprout/Veg Box: 1.5...

Wow, what a headache. Finding a good fan is tough. I thought I found one but it turns out if you want the fan to pull air through a filter you need a fan with impeller blades. So I think I found something in my price range. I'm still not certain what cfm rating to get though. I need an expert...

I found a cheap 500 cfm inline fan I could get. I found a formula for calculating how much cfm you need. Its your cubic feet multiplied by 12. 45 x 12 = 540cfm I think I'm good.

I bought a 400 watt HPS with a 430 watt Son Agro bulb. My box is going to be 3x3x5 feet. How many CFM do I need to properly cool this beast? I'm thinking about getting two computer fans at 59.2CFM each. http://www.cbit.ca/mb/retail_productdetail.asp?Cat=7&SubCat=184&offset=20&ProdNo=FAN-318-410...

Quick Update Added 42 watts to my sprout box (Total 88 watts), no sprouts yet but I am expecting them tommorrow or the day after. I bought a thermometer with a wired probe that tells you the temperature and the humidity. Currently, the temperature is 76.2F and the humidity is at 29%. Do you...

Was thinking about that, what kind of paint is the best to use?

Yup, its temporary. I am going to build a wooden box, with intake, exhaust, the whole deal. I will go tommorrow and buy more lights, higher wattage. As for the lights, smokeybear told me to have them 2ft away for the first few days, then drop it down to 1ft away. Great idea! I'll get one for...

Start Date: May 24, 2008 Days in: 3 My first grow! The germinated seeds are now in the pots. Here are the specs for the sprouting stage. Soil Mix: 4 parts top soil (best I could find) 1 part Schultz Potting Soil (0.012-0.18-0.012)(Has some perlite in it) 2 parts Vermeculite A small handful of...

omg this is complicated. 600 watt is going to cause a heat problem, and its more expensive. What dimensions do you guys recommend for 400 watts?

I think I have to get a 600 watt HPS... 1.5 x 2.5 x 5 = 18.75 sq/ft 600 / 18.75 = 32 watts per sq/ft So thats not bad. I was wanting to use computer case fans for ventilation... is that out of the question with 600 watts? Do I need bigger fans?
