u dont need a FAN right now ... but after 2-3 weeks u have to have it ...
Now, at the stage of growth his seedlings are at, would be a perfect time to have a small fan blowing lightly, not directly on them, but to create enough moving air in this grow room to cause the seedlings to lightly sway.
The lateral stem movement will cause increased stem thickness growth, caliper, and will make for much stronger plants later on.
There is no logic to waiting another 2 to 3 weeks before beginning to use a fan.
GUYS I tried weedd from incadecent light bulbs and just blow my mind ... ITS NOT A PROBLEM TO MAKE A PLANT WITH THEM !!! The problem is just every1 want to VEGGGGGG fast and FLowerrr FAst ... OFC - the better lights the beterr plant
Incandescent bulbs, while not Kelvin rated, are normally in the 2700K to 3300K range, not all that different from some HPS bulbs and even some MH bulbs. Their problem is not so much light spectrum as efficiency. In a way they are similar to CFLs in that to do the job of HID lighting you just need to use more of them, though in the case of incandescent bulbs you need MANY more of them.
The Winter of 1972- 1973, my first attempt at an indoor grow. I used a combination of 150-watt standard incandescent light bulbs and those somewhat purple looking incandescent bulbs that were sold as plant lighting (I do not remember the wattage of them anymore) and I had a harvest. It was not anything close to record setting, but it was far more than I would bet almost every single member here would believe to be impossible.
With there being far better options today it is senseless to use incandescent bulbs, of any type or wattage, but just like with CFls, if enough are used, they will work. You just don't have as many Kelvin temperatures to pick from as CFLs and they do not say what the Kelvin temperature is on their packaging or on the bulbs like CFLs. But the principal is still the same. You have a weak output light bulb that if used in large enough numbers and positioned correctly around a plant or plants will work.
