Are loads of these and a wood work project going to work as well as a 125w CFL for vegging? I could surround the plant with them, right?

Ps For me the wood work project is half of the fun.

they wont be good enough.


You need the 23w versions at least. Get rid of the GU10 sockets use standard household adaptors without protective covers as you need to get the lights within 3inches of the plant.


With 10x23w you should be good for a 1plant grow.


Personally for the watts your using why not look into 150w or 250w HPS?

I've got a 250 hps and should replace with 600 soon but I want a seperate veg so I can have a small plant a month or something like that. So 23w is as low as you'd go.

if you want a small veg area then get some T5HO rather than all the household lights .


100w of T5HO will be ok to grow 1 mother and raise clones.



LST mother to keep her down and clone the new shoots.

10-20 cfls can get pretty damn hot, as well. In a confined space they can get scorching. (At least my 23w do.) Built-in transformer = built in heat source. I second the low-wattage HPS. Your yield will benefit exceptionally for a similar electricity cost.

that would work even better with a reflector behind those bulbs, most of your light is radiating off into space.

Thanks. This is sort of my first grow. The last time I had a friend with too many vegging, so I got the leftovers.

Yeah man if you are gonna put loads of CFLs in there then why not just get one simple 250w hps or maybe a 400w? They are not gonna be much more money than buying all those CFLs and they output much much much more lumens, wich is what matters in lighting

Yeah. I was worried about heat in a confined space. I didn't realize that would be a problem with CFLs aswell. I clearly need a new plan to have a vegging cupboard.

A few small fans should go plenty far assuming your ambient temps are lower to begin with.--IMHO if it's an open area you shouldn't have any problem with heat from CFL or low-wattage HPS, but then you're wasting light and should really have a reflector minimally if using a top-fixture, but in an enclosed area you can/will cook things with enough fixtures. I would suggest you either way consider some form of reflector, even a duct pipe (rolled up thin sheet steel or aluminum?) works great fixed to a 2X4 with the appropriate holes for wiring or fixtures.
