this is my first grow and i have three plants about 2 1/2 months into vegetation and they are 9, 9 and 8 inches tall ... there has been a lot of trial and error ... and i lost and entire crop b4 this one cause of over watering ... grrr ... its good to say that everything is looking good now.. and i think i've gotten the hang of it(hopefully) .... as soo as the biggest on reaches 12'' i am goin to begin to flower ... i dont suspect this will take long either .. since they have almost tripled in size within the last three weeks ... and in the last 4-5 days they have grown about an inch each .... i dont know the strain of these plants ... as they were charity seeds ... but these seeds seemed better than the ones i bought and killed...
