I have ordered from serious seeds before,but as i said before it takes alot work & luck outside to grow & you hate to go through the whole summer to find out that you got by the cops the theives with you plants and then find out that you only got like 5 to 6 plants out of 20 thats female.I grew the white widow & white russian it didnt do good for me i tried chronic it didnt neither,i do see they got the white widow in female seeds now tho,i might try it again.So to me it's worth the extra 10 15 bux to get the female seeds & then you know all your work is for not!Thx for info tho!
