What are the port diameters for this tent? -B

There are three ports with 6" diameters and two ports with 3" diameters. -Greners Staff

Are the Secret Jardin dimensions measured by the outside or inside? -Megan

The dimensions are measured from the inside. Both the inside and outside dimensions are the same minus the thickness of the material. -Greners Staff

I have a 250watt HPS light. What's the best fan/filter/ducts to get. I saw these damper ducts that reduce noise from vent fans, would that work with a fan in this tent? Do you have some sort of basic instruction manual on how to hook up the ventilation with this product? -RSJ

To provide air flow for this tent not much CFM in needed. A 6" duct booster would work for exhaust and a 4" duct booster for intake. If you want a stronger more reliable fan get a 4" inline fan and a speed adjuster or cycle timer to regulated its use. Back draft Dampers stop reverse air flow, not reduce noise. you'll need a Muffler or Duct Silencer to reduce the noise. We don't have a manual for ventilation set up, but we are working on making a video for grow tent ventilation set up. -Greners Staff

Will i be able to fit two 250watt cfl,s in the dr60 what about reflectors. -vince

Although the DR60 is rated for a single 250w HPS of MH light, I believe the heat of two 250w CFLs in that space will be warm, and will require some finesse in your ventilation set up. You could potentially fit two garden Brights in a DR60, but it will be a tight squeeze. You can find those here: http://www.greners.com/sun-system-compact-fluorescent-fixture.html -Greners Staff

Would the GrowPanel 45 be sufficient for this tent to grow a medium sized plant or would I need to get the GrowUFO? Thanks. -Jason

Either one would work, but the results with the Grow UFO will be better. -Greners Staff

I have a 250 watt HPS light, 4" exhuast fan with an attached carbon filter, and a 6 gallon/6 plant hydro grow unit. I need this small unit because of a height limit. At 63" inches and 2' square it will be tight for me but should work. Can this unit fit these supplies in it and still yield three 2' plants? -jeff

depending on the width of the drain tray and hydro unit this should be able to fit in and yield three, two foot plants, however you are correct it is going to be a tight squeeze and not a lot of room for change or movement. -Greners Staff

What are the 3" ports for? From what I understand duct work and fans seem to come in even inch increments, i.e. 4", 6", 8", etc. Thanks -john

the tiny little ports towards the back can either be used for a power cord outlet,or a hose outlet for a hydro system -Greners Staff

in the dr60 what vent system wold be best with the radient hood with 250 watt hps ...intake an exhaust -darrell

Hello, an Active Air In-Line Fan - 6 inch 400 CFM , and some ducting would work for this setup -Greners Staff

Do the flaps in my Secret Jardin Dark Room Pro DR60 II Grow Tent need to be closed during the darkness cycle? -Carla

To ensure that no light is present you must have the side flaps closed. I recommend adding ducting to your intake and looping it a couple times over for the cost effective solution. Otherwise, adding an intake filter will solve this dilemma immediately! http://www.greners.com/i/fans-ventilation-filters/filters-odor/hepa-filters.html -Greners Staff

What t-5 fixture would work best in this tent with respect to heat, space, and light? -dave

If you are looking to have the maximum amount of light within the Secret Jardin Dark Room Pro DR60 II Grow Tent while only creating a very small amount of heat, I would recommend the Sun Blaze T5 Fixtures - 2 Foot -8-Tube! It is only 23.75"(L) x 22.5"(W) x 2.675(T) allowing for it to fit perfectly within your grow tent! http://www.greners.com/i/grow-lights/fluorescent-grow-lights/t5-fixtures-2-feet/sun-blaze-t5-fixtures-2-foot-2-4-8-tube.html -Greners Staff

What size carbon filter would be best for this tent? -Raul

I would recommend the Phresh Filters Odor Elimination 150 CFM or 200 CFM. The 200 CFM would be your optimal carbon filter for the Secret Jardin Dark Room Pro DR60 II Grow Tent! -Greners Staff

How do I set up my charcoal filter outside of my small grow tent? -Tommy

Have ducting lead out of your exhaust at the top of your grow tent to your inline fan, and then to your charcoal filter! -Greners Staff
