looking good m8! dont think you'll have a problom w/ hight. dont you find bio-bizz nutes hard to handel? they make allot of mess, but they are full organic... if you like it, add some of the alg-A-mic, it will do you good.
yup, LST is what "SWIM" wants if "he" is growing only one plant. if its more than SCROG. I did an LST on one of my plants, first timer. its realy easy. check out the thread in sig.
you reccon he can get 5 plats in that space? and if so will he be able to vent it out? imo- he will need the legth to be same as width... (105x105) and all equipment outside the closet. they wont room for them (carbon filter, cooltube out-take fan and water tanks...)
even if you go 12/12 from seed and keep it short, it will get to 70cm hight + 15cm tall pot + 20cm from top of plant to lights + lamp set up and cool tube + carbon filter!!! many things to take in consideration! you will need at least 2m tall box. you can narrow down the width but it will result...
I think u got things a bit mixed up, 100cm is a bit more than 3f. you need much bigger space than that. if you eventually want to grow 5 plants you will need 3x3x2.5 meters WxLxH.
I dont get it eather, IDK, maybe ppl like to be exclusive... plus that behshm guy's question was relevent, the answer is same to bothe- wait 'till at least 10-20% trics are amber and start to flush.
