Hi guys, I am in my 5th week of veg on my first grow ever (let alone scrog)--just giving some time for two plants to catch up (both are a different strain; one was affected by heat, and the other is a week or two behind the rest--I forget exactly), and am thinking about flipping to 12/12 soon.
I am growing 8 Kalashnikova and two Vanilla Kush. The Kalashnikova is far better in scrog than the Kush, grow much faster and are more heat-resistant. I will not be growing the Kush again in the future--regardless of how it burns. I had a couple of incidents with stupidly high heat in the grow room, but have learnt from these mistakes, and won't let it happen next time (which will be in Autumn/Winter, anyway, so shouldn't be a problem). Right now, it gets to about 27/28°C during the day, and sits steadily at 24°C at night. Of course, I am using a 24-hour light schedule (I, honestly, don't know why anyone would use 18/6 unless they were dealing with stupid-high heat). I am using a 600W MH bulb ATM in a 6" cool tube about 20" from the plants--I tried 16", but the plants started to freak out, so I think those 4 extra inches acts as a nice buffer. I started at 36", when the plants were seedlings and lowered bit by bit with time. I will be adding another cool tube with 2 x 600W HPS bulbs for flowering. I am using a 6" exhaust fan with a passive intake. I have a tower fan blowing through the intake ATM--because of the scrog--but had it in there, before I put the screen in. I need to buy a wall-mounted fan, TBH.
My grow box is 4' x 4' x 6'.
I have a bunch of pictures of the entire grow which I'll post below. Hope to get some suggestions/insight--I know I have had a couple of deficiencies! Two of my plants have shown some discolouration on the leaves; one was growing slower than the rest, but the other seemed just as vigorous in growth as the best ones (whilst still being discoloured). I, eventually, gave them some powdered iron/manganese/magnesium in their waterings, and they are slowly turning back to one colour. One plant looked like it had a slightly different deficiency and slow growth with small, thinner leaves than the rest. I put it in the middle of the scrog, and will see how it turns out in flower. As of today, the plant in the top-left of my scrog has gone a little light green. I gave her some nutes, and will see how she pans out. I have been using Tomorite for nutes. Next time, I will be buying better nutes and soil; there are a few different soils going on in there which was merely accidental (will make sure to buy enough of one type next time). I have been using mineral water which has a low amount of sodium in it (I know, I know!), but has a pH of 6.7--the best pH I could find in bottled water where I live (some were, like, 7.8!).
When do you think I should flip to 12/12? I think the screen is filling out nicely, and the strongest plants have 3-5 bud sites poking through the screen. Don't want it to get too hectic in there! I guess I need the lower bud sites to get close to the screen, at least, so they don't end up under the screen by the end of stretch.
As I am approaching 12/12, can anyone give me some tips on making light boxes that actually work (mine is a shoe box ATM--jokes)? I am just going to seal any holes with a couple of layers of black duck tape.
