I had a white widow plant growing about a month ago, I gave it too many nutes and it died (or so I thought, as it's still weall alive in the garden somehow) Whenever I exposed it to any natural wind it blew right over because I was growing it indoors with a tiny 12 volt fan blowing on it. Now it's out in the garden the stem has thickened and it can stand by itself so that's okay.
I now have 3 white widows and 3 holy grails growing in my DIY closet under a standard 40watt CFL (pathetic I know but I can't afford a better bulb right now) with a homemade hanger made from a sheet of aluminium I bought on fleabay and the same 3 speed PC fan bodged up to a 12v power supply. They are only around 2-3 weeks in (I don't keep count) so you'd expect the stems to be thin, but I don't want them to get to a decent size and start budding only to fall over under the weight.
Am I just being silly and over time they will thicken? Or do I need stronger wind stimulation? The current fan is gently blowing on them, so they wave gently but it's not hurricane wind speeds..
As long as your plants are moving you should be fine.
You need to get the cfl closer 6" and cool it down with an exhaust fan.
Your light should be about 1 1/2 in above the plants.
40 watt cfl??? You will never get a good thick stock with that amount of light. Address theissue it doesnt matter how much wind you have if they cannot grow.
As long as you see movement your air movement is fine, look at lighting.
Wait until you can get more lighting, 40W is not enough, are you using an incandescent bulb or cfl?
