if youre worried about some plants being taller and all that just set your short ones on something to raise them up phone books work well and who actually still uses them still for anything else
keep them at 18/6 until they are to the height you want them to get but remember depending on the strain when you flip to 12/12 they will grow 2-3 times that height
they actually work very well a local hydro store actually recommended getting a mirror when i started growing and then found one of those big ones from a commercial bathroom for free it is now my grow floor
they definitely would have a hydro store in a big city and when you find a place itll be in the lighting section and look like a shiny tube of wrapping paper the thicker the size you buy the better it holds its shape
4. Is it safe to grow other non cannabis plants such as lemon trees,dragon fruit tree,starfruit ect.ect. In the same room as my plants??? Some plants don't play well together. Tobacco and cedar come to mind. Do some research specific to the other plants you want to grow.
hey i always...
if you mix fox farm ocean forest and roots organic together you dont need to add hardly any perlite cause roots organic is FULL of it and then you almost dont need any nutes during veg
no you cant smoke it (i think...)(i personally dont smoke it). i just grow it cause i figured if im going to be growing and having bright ass lights why not grow things for everyone. and trust me the cat isnt allowed in my grow room cause i too would worry that id come in there and have a zonked...
i usual transplant my plants as the light is coming on cause when i transplant i also water the plant and i like them to have a full lights period to drink the water when i put it in but i dont personally know if its a good idea or if it really matters its just what i do
shouldnt be any problems t5's dont get too hot and with those fans youll have nothing to worry about but just to be safe try not to have the t5 touching the walls or ceiling and as im sure you already just keep it on the 18/6 light cycle
