[quote=analog;1313779]So I have a 120 v 13w bulb here........ 60Hz, 3000k.

Are these BETTER to use then 60w bulbs? All these different numbers confusing me to shit lol.

analog

3000k has more red in the spectrum, which is better for flowering.

6500k has more blue in the spectrum, which is better for vegging.

Your best advice is to stop thinking altogether about equivalence.

The whole subject concerning equivalence is not very useful for the MJ grower at all, ever - because you cannot grow with an incandescent old fashioned light.

What analog said.

When you look at CFL's, and you hear people saying "I have X amount of CFL's" what they are quoting is the ACTUAL WATTS of the CFL. Don't worry about what they are "equivilent" to in terms of Incand. bulbs- those numbers are a guideline for lamps, for people giving up their 60 Watt Incand. reading lightbulbs for CFL.

Now, in general, a rough rule of thumb is compare Watt for Watt. If you want to try and replace a 200W HPS, try at least 200 ACTUAL Watts of CFL's, plus a little to be on the safe side.

Bear in mind, without special fixtures, CFL's are harder to cool. It's hard to find a ready-made air-cooled hood for 100% CFL's . Most of them are specialty fixtures for HPS + CFL's.
However, feel free to make your own mini-cool tube for a big CFL bulb.

And also remember, in terms of heat, actual watts = actual watts, so if you have 400 Actual Watts of CFL, they will put out about as much heat as a 400Watt HPS, just spread over a slightly larger area.

Hope it helped.

so 2 13 watt bulbs are 26 watts lol?

Can I buy 60-120 watt cfls from hardware stores?

May seem like a dumb question but why would they sell 60-120 watt ones if there is 13 watts? What's the difference in terms of lighting for the average house for average people.

I was also looking at this picture and was wondering what those socket things are called where it doubles the amount of lights that can be plugged in there.

Futuregrower

1. Yes, (2) 13 Watt bulbs = 26 Watts used, just in 2 bulbs. Same as HPS- (2) 100 Watts = 200 Watts.

2. You can get whatever you want from hardware stores- it depends on the store. Many stores have Small, medium, and big CFL's. Biggest I saw was a 75 Watt CFL, I think it was a 300 watt spot replacement.

3. Why do they sell 400Watt HPS if there's 100Watters? Why not? They sell what people will buy. Remember , go by ACTUAL Watts used. When you see "60 watt replacement" it means it is for people replaceing a 60 Watt Incand in their home.

4. I call those things that look like a " Y " a "Y" socket, or a double socket. Tell the guy at the light center and he'll know what you mean. Menards and places like that have 'em for a few dollars. Get the ceramic ones- the plastic ones are mostly crap, IMHO.

5. Remember, if your space is 1.5 X 1.5 (about 2.25 Sq. Ft) you want about 50 to 100 Watts per square foot. 75 is a good bet. This means you want about 150 to 170 Watts. If your grow box is only 1.5 feet high, where are the lights going to go? A CFL bulb is probably close to a foot from the ceiling to tip of bulb, with a few inches thrown in so the plant isn't touching the bulb. A 150 Watt CFL bulb gets toasty. So does a 150 Watt HPS. Can you do a DIY Cooltube and 1 big bulb?

I was planning on getting 2 Y sockets, putting 2 60 watt CFLs in each socket. So about 120 watts for each plant.

Would have inline fans for air circulation, I figure if the house temperature is at 70 degrees, and the air in this small box is CONSTANTLY being refreshed in an out, how hot is it going to get in there?

so 60 Watts X4 = 240 watts over top of 2 plants. The plants will be LST'd laying over into the other pot being about 1 foot long, but only coming up a few inches from the top of the pot.

I got the dimensions and if the 2 little 1 foot plants will be being hit with 4 60 watt CFLs with the air constantly being refreshed, you think it would work out?

Or would 2 60 watt bulbs be sufficient for such small dwarf plants?

Should I also go for bulbs that say 60w, or are 13w bulbs equaling 60 decent, yay or nay lol, still confused on that.

Futuregrower

If you use the bulbs that say 13W, replacement for (or use in place of) what you have is a 13W CFL. You want to know what it ACTUALLY DRAWS Wattage wise, not what some yahoo at the factory says it is equal to.

If you have 240 ACTUAL watts, that's as much heat as a 250 Watt HPS. You will burn your plants to a crisp in that space.

Dude. Get the biggest CFL you can find, plug it in, and put your hand on it. After you get back from the burn unit, let me know if your plants could stand it, ok?

Why not just do this- get a 150 to 170 ACTUAL Watt CFL, or (2) 75 Watters. Build a DIY Cool tube from a clear hurricane lamp type glass tube, or one of those "Bake - Around" tubes they got on Ebay.

Put it Fan>>>Cool Tube>>>out thru a filter (for smell. you don't want any if you're going stealth). That way, you'll keep it cooler. Prior to putting the plants in, put a thermometer in there, shaded by a little piece of foil in an upside down " V ". Let it go 1 hr, just like it runs when the plants are in there. If the temp is ok, like below say 80* F. or so, good.

If not, you need a taller box, more ventilation, or less light.

Does it absolutely have to be the Autoflower micro grow? Are you that pressed for space, or do you simply not need much MJ? Cause a 1.5 foot cube is awfully tiny, you limit the amount of heat you can generate in there.

You could also get regular seeds, and put them into flower from seed, making them dwarf plants.

But I think the 1.5 foot ceiling is gonna be problematic- remember the plnts have pots under them, so an 8" plant + a Gallon pot is about 16 inches. This leaves you with all of 2 inces for lights and venting.

watt= 1 joule per sec...it is a basic measure of how much energy is being consumed by your device.

Lumen= is a measure of VISIBLE light or a measure of the perceived power of light.

13 watts equivalent to a 60watts means for 13 watts of used power you'll see what you used to see from a 60watt incandescent. From a PERCEIVED lighting perspective that is a good thing. I do not know if it means the same to a plant because there is something called PAR (photosynthetic active radiation) which is a much better guage for plant growing. In effect it rates all the spectrums that a plant can use and discards what a plant does not see...such as greens etc. and rates the bulb outputs accordingly. Most bulbs do not yet use the PAR rating system.

To make it simpler...We can see spectrums that a plant can not...green( 560–490 nm) for instance. So when we see bright light we think it it better than a dimmer light for growing.That is not always the case because plants can "see" light that you and I do not(over 700nm or under 400nm).
