are you talking about spending money on a light? if yes, then go for the 250w MH, thats good for a whole bunch of seedlings, or a couple of plants. they were ;eft for a bit too long under one of those chinese led bulbs and got a tad burnt, but now there under a 250 w mh light and doing ok, its still cold here in the uk, bit too early for concervatory growing, but cant be saaed to get the tent up n running for two plants, the one on the left is an auto i just topped and the right one is a ace seeds milawi sativa or a mexican sativa from sensi seeds, i didnt label, so i think its a mexican. my last milawi was lighter in colour and leaves were more slender then that, still got some seeds left for my new grow this year, but wanted something for the garden (pollytunnel).
