Best video ever! Great comparison (and I love the attention to detail with the empty grow tents).
I never realised basil was such a big market though. I'm feeling very behind the curve and as much as I love 420 I'm now sold on basil, and I'm off to find some good vegetable/basil threads. That's where it's at apparently. Thanks for everything 420..... Baaaassssiiiiiiiilllll!!
I'm a little skeptical about your measurement technique. I've used the Ocean Optics system you are using to measure and I've found that the fiber probe is very very sensitive to angle. For your LED light you have the fiber pointing directly at the source, for the HID the fiber is not pointing directly at the source. Also, what did you use to calibrate your system?
Ive been doing alot of reading on flushing lately, what do you guys think of this thread?
Lucas Formula: No Flushing
it seems there are alot of professional growers that dont flush at all, Corey from BPN being one of them if I remember correctly(im waiting for him to answer my e-mail), same goes for the guy that designed my lights, heres what he said on the subject.
"There's a few schools of thought on flushing.
There's the 2 week pure water flush in soil. There's the 2 week pure water flush in hydro.
Then there's tapering down the nute levels towards the end of flowering so at the last days there's really low PPM's.
In some sense, I flush, but I do not do it for 2 weeks.
What I do (hydro only, I quit soil long time ago, it's just dirty), I start the plants as normal, and maintain a normal PPM for the entire grow until the last week, then I taper it down until the last few days, and I time it so there's little to no nute PPM's by harvest day. Water PPM's don't count. I try to have zero nute PPM's on the last 24 hours, which I also do with no light at all.
As for black ash, that has nothing to do with flushing or not flushing, that's due to moisture still in the buds and not burning all the way. A proper drying and a lengthy cure will fix that.
The structure of the buds will dictate how long the dry and curing needs to be. Different strains have different bud structures. So there's no 1 correct length to dry and cure for every strain.
The stem snapping method works well to check dryness. Curing should be at least 30 days no matter what the strain is.
I did a 75 day cure on my Herijuana. That was some tasty stuff, and it burned clean, all white ash, and I grew it with full nutes till the last week, and started tapering it down until there was 350 PPM at harvest time. My water is 125 PPM.
The last couple of weeks the plant packs on a lot of weight, and a full feeding is necessary for a good yield and full potency. It's all about feeding the plant what it needs, keeping it healthy, maintaining all of its leaves, making sure they are nice and green until the end, and timing it so you run out (or almost run out) of nutes at the same time harvest comes around.
Give it a try, you'll be surprised."
when he mentions black ash hes right imo, I personally saw that the ash was dark grey before the cure and now after almost 7 weeks the ash is almost white.
The final 2 weeks of flower is the plants "fattening up stage" right? so why would we want to starve the plant at this crucial stage of developement? I would really like to hear what everybody thinks about this subject.
Ive read several threads that say the salts are stored in the leaves not the flowers, when you flush the leaves turn yellow and die not the flowers so that kinda make sense to me too.They say that a proper manicuring of all the leaves will greatly improve the taste of your nugs.
Ive always stuck to the 2 week flush with final phase and it works well but im wondering if its really nessesary to flush for that long and im wondering if this tecnique affects the yield.
Im looking for feedback from growers that have tried different tecniques here because im already very familiar with the 2 week method
