i would like again your opinion on this......it is bloody snowing outside....it is getting even worse day by day....is the third day that i have the window closed....no fresh air coming in .....i just go in the growing room 4-5 times a day in order to change the air a bit....i talk to them and approaching from the top i directly breath on their leaves....it's the third week now from seed and the second week on 18/6...if i change back to 24/0 will that stress the ladies? i get a little bit worried about the temperature drop in the room as it has lots of height till the ceiling and the heat from the hps lamp is not a problem as initially thought would be.....also i read in the Dutch Passion homepage that a lower temperature gives more females but my seeds are feminised anyway.....anyone reply....need advice.....third week and have not used any fertiliser yet...just mineral bottled water....and lots of love.....
