Yo do your idea with the shorter run for your HPS, and then have a bank of t5s that run the full 18/6 schedule. You won't flower unless you have autos and your plants will be KILLER

Hi y'all, nice thread. I've yapped about this topic before and am getting a little sick of copy & pasting myself so if you want the scope go crawl through my past posts like I do yours when you say good stuff :) Quotes from this thread: My question: What chemical residues were you expecting...

any chance they "received" that information when he applied for a dispensary license?

I was trying to just edit this as an add on to the beginning of the last post to save thread pages but RIU insists that 2 paragraphs is under 10 characters and keeps busting my balls about it so F it here it is:

so PAR specifically refers to the types of light which are known to be useful for photosynthesis---this is important to note because you have to remember that the whole range of the electromagnetic spectrum is considered light, IE radio waves are light waves. Your 3300K MH is rated thusly...

heres some mildly related tidbits i pulled from my few journal entries: Why is all this relevant? Well, we need to always remember that we are responsible for recreating the plant’s natural environment. Chew on this (wiki on Rayleigh scattering) The strong wavelength dependence of the...

they are good now RIU just toying with me apparently

Top graph- PAR, how the range of the visible light is perceived by plants (via pigment absorption) bottom- PUR, how the range of visible light is USED by plants (based on CO2 consumption tests) (link may be bigger) http://upload.wikimedia.org/wikipedia/commons/7/72/Par_action_spectrum.gif...

usin a carson zORB, it will do the job and a bit cheaper than that one. Doesn't seem to have quite the range however. That link states the scope is sold out fyi

also some commercial prepared soil companies will add predator mites to their mixes, if you state the source of your soil it might add to the ease of identification. (I am thinking of hypoaspis miles in particular, they will eat fungus gnats before they mature to flying adults, so you won't see...

touche We all have our hoops to jump through and wheels to run on, no? hoping to start my own lab actually.

brand? I have posted some interesting stuff on PAR meters in the past, if I can find something related to your unit I will share it. PAR meters dont perform consistently with differing light output types so you can have two meters differ on the same sunlight reading, and you would expect them to...

From wikipedia on Malathion: Malathion is anorganophosphateparasympathomimeticwhich binds irreversibly to cholinesterase. Malathion is aninsecticide of relatively low human toxicity; however, a 2010 study has shown that children with higher levels of organophosphate pesticide metabolites in...

i would say scrap this years crop and treat the ground with one of these if you plan to crop any solanum (nightshades such as potato/tomato) in coming years: Use of fungicides Fungicides for the control of potato blight are normally only used in a preventative manner, perhaps in conjunction...

spinosad and hypoaspis miles (predator mites) they can tolerate the azamax/spinosad as soon as they build up population they will control the thrips in my opinion, since Azamax is neem extract, it should be used simultaneously if at all and never sequentially, unless you are trying to breed...

everyone has their technique for sure. just sayin, in those 'rooters, that 3:7 just became 6:7 and im being conservative because i'm pretty sure I see the white of a new rootlet on #7...definitely something up with the other run of seeds (with the black stuff) not correlating the presence of the...

started doing rapid rooters and older (these seeds are super fresh) seeds have been almost 100% germ rate so i'm stickin with my technique, but dirt all the way after that of course

I bet it will work, been meaning to try this. Was also wondering how it would affect this experiment to air-layer the branch so it had roots too....

i apologize for my brevity as I am forced to type one handed, but I am 90% sure it is an early envelop of the ovum. I was handling a few hundred seeds and several black/silver flakes were all over my hands afterwards. Yes it will scrape off the seeds but with enough handling it seems to come...

Not the most scientific site, http://forum.sensiseeds.com/forum_posts.asp?TID=496 In fact, a close reading implies that they are making this point about pollinated pot: Once pollination occurs - when a pollen grain adheres to a pistil long enough transfer its genetic information - that calyx...
