I need to try a Sputnik for testing as I keep reading GOOD things about them.

FYI, CO2 will be a limiting factor and make that much light a waste, without supplementation or plentiful ventilation sources from outside the house (or you leave windows open), if your grow is 5 sq ft (2'x2.5'). If it is that small, asking 80 dry grams per square foot is probably a pipe dream. But again, and sincerely, good luck, and put up a journal on that grow.

Hi Dragon,

Thanks for the comments. A gram per watt is probably a pipe dream but a fun one anyway . I am only growing personal so 1/2 that would probably do. I looking in to the PL stuff and it is pricey. I saw a setup on craigslist last month when I was broke.

It sounds like you know your stuff and are a fan of experimentation and scientif method which is a big bonus in this game. See you around man.

Check out my grow. Just gathering supplies at the moment but we all gotta start somewhere!

This may be an ignorant question - but dont the cool tube reflectors reflect less light back down?

Yes they do.

Hey dragon ... Did you happen to remember how much loss there was with the internal vs the wing external?

Thanks in advance.

it is somewhere in my notes, but what I do remember was the difference in hotspots. The internal one lit the hell out of the four closest sensors and was respectable at the sides, but was weak at the ends and corners. The external reflector was barely dimmer up close, but much more even, and imo, put out more useable light. I've seen lots of pics of cooltube grows with the internal reflector, and many seem uneven in growth throughout the canopy. Are you using a dr60 tent? A 400 is major overkill in that space. Look into ceramic mh bulbs, as they throw way less radiant heat. They also produce squat, dense plants. I have nor used one on a grow yet, but have one and have played with it. I think these two factors make them ideal as small tent bulbs. I talked my girlfriend into a new grow space foe Xmas. I used the " honey you could get your closet back, plus we'd have a place for the vaccum." argument. I know her too well. I get to build a space out of drywall, properly insulated and professionaly wired. Two 4x4 spaces for flowering, a 3x3 test flower, a seperate 5x6 veg space, and a mini split a/c. And an arangement at my grow shop allows that I will know in a year the hyperbole behind much of the grow equipments claims. Ceramic mh, uvb supplementation, & extended dark periods at the end of flower are the first myths to slay. I get to be the mad scientist my momma always feared I'd become.

That sounds like so much fun! I would love to create a space custom for my garden. My tent is 36x20x62 so a 400W (55k lumens) will give me almost 10,000 lumens per sq ft. Maybe a little overkill but better to be over than under. That is the primary reason I went with a cooltube so I can et rid of the heat issue and set the light a few inches of tops. Should make some tight nugs

Sounds good just make sure to acclimate the plants to being so close. Too intense of artificial light can cause stress and odd things to occur.

And I appreciate the post. +rep! You mind taking a look at my cab and telling me whats best for my situation? I have the cool tube thing in mind but I always wonder'd how much is actually being lost because it would be just to good to be true to be a "cool light" kicking out that much energy? My cab is in a closet and QUIET, COOL & ODORLESS are my priorities. I was thinking about doing a cooltube/carbon scrubber combo. Only, problem is that like a fews bux and wasted hours later... am I gonna regret that shit? lol
