thanx for the tip IthoughtIknewitall but seems a little bit strange, as 9 inches seem too little...it's less than a foot tall if i am not mistaken....less than 30cm....if i flower them at 9 inches (around 24 cm) as you suggest, around what height would i expect them to finish and what yield should i expect to gain? with my calculations i suppose they will be there (at 9 inch) in about 2 weeks....that will be exactly 4 weeks from seeds......thanx for the suggestion.....furthermore i would like to add that outside is snowing right now and i have closed/sealed the window as it is below zero....would not want them to freeze to death......cheers
