Thats the first plant i found LolCould be a couple weeks. But that plant looks pretty sad in my opinion. I would shoot for something a bit better.
I'm vegging outside with strong sunlight i'm living in south italy and weed plants grow very tall if sativa, the soil is red clay but i'm about to ammend it with some perlite and peat... So dalek is right only 2 week, i'm very happy thanks to allI think that depens on a few things, Are you vegging it outside or under light, how good is the soil, has it got plenty of food in it. Dalek is right about 2 weeks
Thank you very muchI'd say about ten days to get that size/advanced.
Good luck with the grow!!
