So I was under the impression that Vermiculite is like Perlite and got some for the potting mix I'm making. My book says it sorta retains water.
Potting mix:
3 gal peat moss
1 gal humus
1 gal leaf compost
1 gal mushroom compost
1 cup fine dolomite lime
~1cuft
+ 1 gal Perlite
+ 1 gal Vermiculite...
in all my grows so far the limiting factor for mega growth has been air, I never used ventilation. maybe some ventilation would help i do not see any. but other than that i think you're in for a long wait since it's a sativa. with no air a bigger plant gets a certain size then just STOPS because...
my book says 1cup per cuft. most potting soils do have low ph thanks uncle ben. you can't add too much lime(dolomite)(and don't get the pellitized that is for lawns), the ph won't go higher than 7. it's just a waste to add more and can get cakey. i really don't know why it's not added to more...
this has happen to me. I made sure it didn't get that hot again by switching grow location. more pistols came in milky/white with good calyxes. the plants turned out fine.
as messy as it looks you might be right on. make sure there are no shorts between outlets, it looks like you've done this (like the black and white have to be the same length) i know if it's not this way on a regular lamp that plugs-in things will FRY. someone correct me if I'm wrong but i think...
blueberry is the best ever. got a bag of it many years ago and haven't found anything better. since then I grew some of my own, same, dutch passion, still got some a year later and it's smoking great
tent. if not use the dryfoam insulation, great stuff. put widgets over the foam and staple panda to it that should be enough. 2400 wants is alot of wants lol
you could also get another inline to work in conjunction with the carbon inline but have a hepa on it and have it pulling air into the room instead of the passive so there are no odor leaks. make it a 4" if you decide to do it, no need for a 6" intake.
I would do pic #2 except switch the inline and duct fans around. Maybe get another duct fan since you have two lights. then leave on the duct fans for the duration of the light cycle and run carbon for 15 mintues every hour or so. this is the best electric saving option and grows plants the best...
