Help set up new medical grow suggestions equipment

on what? l.e.d or hps/mh and i rather save myself from headaches as l.e.d isnt mainstream yet.

by the sounds of the list it could it be aeroponics?

You ever wonder how much of that spectrum goes to waste because the plants can't see it?

[khyberkitsune]

im not much into l.e.d and its a route i probably wont consider for the time being, thanks though but if anything it might be supimental or as a side thing but otherwise i plan on veg with mh and hps to get as much speactrum as possible. but im looking for something that so yes im starting from scratch

You do not want as much spectrum as possible. Green and yellow wavelengths act as growth inhibitors (that's the only effect green has, BTW, on cannabis, besides maintaining a baseline photosynthetic rate which is better achieved with targeted-spectrum lighting) and the majority of wavelengths are still not at peak efficiency. If you want 'full spectrum' go with trace amounts of everything with reds and blues being most dominant and the rest being about 2-3% of the total output. The majority of biological processes are controlled by red and blue. Some green and yellow might be used - this can be determined almost primarily by the leaf color - light it won't use will generally be reflected or allowed to pass through completely without being absorbed (depending upon quantum efficiencies and whether or not the plant has structures made to handle particular wavelengths of light.)


That aside, you could do what you're looking for with vertical MH/HPS lighting and vertical/coliseum style growing, but it will take quite a bit of space to get done, and overall, if you intend to keep on with your setup, you'll be spending quite a bit more on cooling and lighting over time than you would going LED. I've got MASSIVE plants with LED versus my T5HO in veg in equal time rates, and my T5HO knocked the crap out of my HPS bulb veg-wise. I think the MH would've beaten the T5HO, though, given proper color temperature. For flowering, I'm still testing with LED but I'm easily nailing what I couldn't hit with HID bulbs or T5HO bulbs normally.

Not many will say go LED but a few of us know what we're doing (I'm an official Dutch gov't genetics preservation specialist,) and we can point you out in the right direction. Stra8outtaweed has units that I wish I had, given my particular growing space dimensions. If you had a large area to go with, I'd be asking him about what he has, as it's likely more suited to your needs so he can tell you where to look for them.

Just as a heads-up, My Hindu Skunk is rated 15-20% THC content amongst other cannabinoids. I most certainly get that under T5HO to HPS lighting, no problem, the issue is yield for me unless I do vertical. Under LED, same genetics from same mother and same technique/timing/nute regimen, I'm pushing almost 30% THC content amongst other cannabinoids plus I have the yield I need to make sure my leg doesn't bug me (3/4 ton pickup truck head-on while riding a 10-speed, bro.) Better quality and better quantity for less work and less cash. Put it like this, assuming all goes according to plan, 70+ grams from 70-77 days from clone rooting (2 weeks veg 8-9 weeks flower) using a 50w panel on 18/6 veg and 12/12 flower puts me at 50.4 kWh for the entire grow (not including air pump, which about doubles that) and about $10 in nutes. So for say 77 days of my time, I get about as many grams of bud for maybe 15-20 bucks. See how quickly you can scale that tiny operation up? I'm doing this in a PC case. Yes, initial setup cost is expensive, but it'd be WELL worth your time, as you'd probably dose less with far more potent medicine. You'd also save far more money on cooling and ventilation costs, plus bulb and ballast replacement costs.

Actually, after a quick bit of math (and making sure it was right at least according to my power company and to one of the cheapest suppliers of lighting I can find) it seems LED is just now starting to become a short-term cost-efficient solution, as well, depending upon your precise needs. I see some 1.5w diodes going for about 2 bucks, and even at 120 degree emission that's enough penetration for deep ScroG grows up to 18 inches.

Lots to think about, but assuming you've got the space and initial cash, go with Stra8's suggestion, you'll love yourself for it rather quickly once you see the power savings and quality/quantity increase.

Dude, I quoted you! A great deal of the spectrum produced by HIDs is not usable by the plant, not to mention the heat off of the bulb and ballast.

To be as clear as possible - what Kyber said. Wish I knew half as much.

man something happend with my connection i had to re post this ....

so on veg most mh say 2 mh and one hps to get a bit of red or alittle bit red is a no no?

i was reading that on flower that in order to get more crystals you should add some blue as a side or suplitmental to the hps....

would this work on veg as well as im explaing it?

also the vertical colisium grow what the benefits ?. i need inline fans like the 6" or the 8". but does the exhaust have to match or exeed intake amount?

also as far as the led what panel would you point out to ? is it ideal only for veg or that panel works for flower as well?

does the distance or intesensity affect hugely ? i thought this was somewhat of an issue, since i lost what i wrote on the rest of the led i'll wait for your response thanks guys....

I can't answer your HID questions. Sorry. Your intake should be 1.5 x the out take. Someone please fact check but that is what I recall. Get a fan speed controller on you shopping list. This will allow for micro adjustments. Check these sticky for detailed instructions on fan size. This one is good: Fans - not just blowing hot air but this one is more appropriate in terms of assessing fan needs: Noob's guide to growroom set-up. See chapter 2 for the fan discussion about half way down the first page. It gives a measure for calculating needs. And those two stickies are excellent for all kinds of setup information.

As for LEDs, there are a number of people here doing LED grows. I'll be one of them shortly. See moody420 who just started a grow. See str8outtaweed who has done a number of all LED grows. And there are others. Just look at some threads going about LED and you will find them.

Keep it simple man! Looks like you'll need at least an 8 oz harvest. That could be accomplished with a single 600w hps and another mh light for veg. I don't know how much you can legally posess but there are ways to get around that as well. Make edibles, hash, etc...mature plant hanging upside down is still considered one of you're mature plants. If you're working with a small plant count, just grow them out big. If you're new to things, try to keep it fairly simple before jumping into hydro or aero. Organics are easy if you have the right things going on in the soil. It's easier to grow then flower than to run a perpetual harvest. Hope this helps :stoned:


ps, to answer the question I believe its UVB lights that can increase resin or "crystals"

[gus738]

hey thanks for the reply,


turbo 8oz of wet or dried bud? how many plants would i need to get that amount in the minum amoung expected? or can i get say 1 oz per plant is this realistic? thats i have no restriction but the last time i remember the law was 6 mature 12 inmature. but im not concern about this or a limit.

im mostly want fastest (aeroponics?) high yeilds quality bud.
so i thought of having 2 rooms a veg and flower, is this consider a perpetual set up?

bigsby
i did read that thread that guy explains pretty good but some stuff i dont get, he has not been active for a while.

im just suprised this thread isnt flooded with post maybe people out somewhere?:stoned:

uvb is not good for plants nor for humans so i heard or i remember reading but i guess we can forget about flower i just want to start by the end of month towards may.

uvb is a controversial subject. you want high yields? use extra co2. 8 oz dry is what I figured if you're smoking up to an 8th a day, you'd need that big of a harvest every two months. Easily accomplishable with a 600w or 1000w for flower :stoned:

[gus738]

yeah a 600 or 1k does it, i wasnt or am not sure yet but veg room of 4x4x8 and flower what whould be ideal?

first time on veg 4x4x8 1k mh and 1 600 hps or 2x 600 mh 1 hps ...

and flower same size. or would it be ideal for smaller room less intesity of 1k and more coverage?

im thinkin of giving each plant 7 thousand lumes
