Hello people thought id do a proper grow diary as i tried last time but it didnt work out

this is my SECOND time growing and a few tips here and there would help, firstly i have the great cheese in 1 pot - the superskunk x 2 in serperate pots and an unknown my mate gave me he bought some deer seeds but wont tell me wot it is i have to wait and see

il get some pictures up of the beautys in a little while and will post them up, Im growing my seeds in a 6ft wide 10ft up greenhouse which is insulated with half bubble rap and at night i put cloth over all the plants to keep them from frost - it gets so f**king hot in there now i cant wait to see wot its like in summer heat

anyways my questions are - when can i top them and how do i top them ? im experimental so i would also like to know the method of the sea of green i have all the mesh to do so - and i see on youtube some guy cut his main kola stem in half and at the end of harvest he had to main kola's - and last but not least - 2 of my plants are growing out of control and the other 2 are just sitting there any idea's? im going to take the pictures in half hour so theyll be up before 1 oclock - NEED HELP THROUGHOUT THE GROW IF POSSIBLE! cheers
