Best book? If you only had to pick one...

[SmokinErb]

So I didn't know where to put this, but seeing how I grow indoors, this is where I stuck it.

I used to own Jorge's grow bible, however I lost it and I'm looking to replace it. I'm sure there are better options out there seeing how its full of rather outdated information.

So what you guys think? If you only had to pick ONE book for reference, what would it be?

Marijuana Horticulture: The Indoor/Outdoor Medical Grower's Bible is still the best book imo...its the BIBLE

 

[SmokinErb]

Yeah, that's what I was going to get, but there were a few other options there, so I decided to wait and kinda toss the question out there. Doesn't seem like anyone's really interested so I'll probably just go pick out one I know worked well for me.

Who needs a book when you have references like IC MAG & OG archives? IMO books are for beginners. Once you have a few grows under your belt, you should know the basics and just have to search here for the more advanced questions. JMO!

 

[SmokinErb]

Aye, well. I look at it as you can never have too much information on hand. Say there's an emergency situation, I dunno, you wake up and are having horrible stress, nute burn, or maybe you've got a new insect infestation you didn't notice and never dealt with before.

Wouldn't it be nice to have a book around? A lot of times I think they're really handy for quick cross-references when you're just not sure about something, and a lot of times faster than ICMag or whatever.

I truly do love being able to take a picture and post it up and having many experienced growers say "hey! this is your problem, here's how you fix it." This is by far my most valuable tool right here, but once again, sometimes it's just not feasible. Hell I can get the grow bible for free online, but I like to have a hard copy... just in case.

Kinda like a condom, right? I'd rather have it and not need it, than need it and not have it.

Best book you can have for a nute problem. Has more pictures then most books I've seen. Personally when you are consulting a book, you are reading one person's experience or opinion. When you do a search here, you will find multiple people's opinions.

And that is JMO..............

I read most of the books out in m time, and I found The Cannabis Grow Bible second edition by Greg Green to be the most comprehensive. The Garden Saver by Stitch is good, but it's here for free.

 

[NinoBrown420]

I own many books on this subject,and while I am a firm believer in cross referencing info from more than one source,if I had to pick just one it would have to Jorge's bible.I found it to be a lot more comprehensive that Greg Green's book,although that too is a fine read.But for real,read as many books as you can find.

 

[GroBoy2000]

I have 2 of the Jorge Cervantes books, the indoor/outdoor medical growers bible, and the guerrilla growing outdoors. I find the medical growers bible to be lacking in a lot of practical hands on advice. It tells you most everything you need to know though to setup small or big, but for such a big book, it can feel very basic sometimes. The other is a better book for it's size, but both of them stress a lot of points that go right out the window here(with great success too)

I'd go with the Marijuana Growers Guide from Mel Frank, for me it felt a little more hands on without as much nonsense. But I can't disagree with Nino, the more read the better.

Cannabis grow Bible by Greg Green
Cannabis breeders Bible by Greg Green
Marijuana Garden Save by J.C. Stitch

Bible is an accurate description! I always have one of those books beside the bed, at my desk or in the room! ICMAG is great when you have time to sift though 20 pages of discussions coming from opposing sides, but when I just want a quick, reliable answer... the above books are great.

 

[secondtry]

I would not recommend a cannabis book because all cannabis books are full of total BS, sure there is some accurate and good info, but way too much total BS and non-science like using watts, lux, lumens, and so called "PAR" as a measure of irridiance.

Ed, George, etc, are full of BS.

I would suggest google scholar and good key words searches, or other online journal article search engines. Some white papers are free, most are not, but one can get them for free if they ask the right people whom have access to these databases (e.g., higher education libraries).

?

how is that data 'BS'?
lumens & lux are interchangeable... just a conversion factor... lumen measured in feet, lux in meters...d

Those are not a measure of light (photons) plants use.

par is the only manner to truly guage effectiveness of light on plant, is acronym for

p.hotosynthetically
a.ctive
r.adiation...

PAR tells us "what", i.e, wavelengths of 400-700nm, while PPFD (Photosynthetic Photon Flux Destiny) tells us how much/often.

ieg, the light that plants actually use... that is standard in crop production field... usually between 300-800 nanometer wavelengths...

PAR is a term of the photons plants use (400-700nm), it does not measure/count photons.

btw, sunmaster lamps state a paw-watt on their boxes...

There is no such thing as "PAR watts" for use when quantitating incident photons plants use, that's a made up term by SunMaster and the really stupid part is they claim it's photons per meter^2! They fogot about time! A pyranometer is not used to measure photons for plant growth, that is what a quantyum sensor is for (among other more expansive and more accurate pieces of equipment like a spectroradiometer). It needs a time variable, ie., by the second. PPFD is the photons within PAR range which land in a meter^2 per second. SunMaster is lying and trying to sell lamps, not use science (I emailed them about this but they ignored me, just like LEDGirl, surprise, surprise).

even posted a link on how to diy a pyronometer, to measure light plants actually receiving & converting to usable energy:

You need to use at least a quantum sensor for that (ie.,. a PPFD meter), and then you need to "weight" the photons per wavelength to their relative ability to drive photosynthesis. Please see QFD (Quantum Flux Density) by K.McCree and YFP (Yeild Photon Flux) by K.Indana.

This is a gold mine of cannabis growing laboratory research
https://www.icmag.com/ic/showpost.ph...04&postcount=7

as for the measurement of that light, micro-einsteins per meter square incident on leaves...

That's the problem, you need a time variable which in that study is represented by PPFD.

check link in sig

lighting conversion data

I will but I can guarantee you that info is wrong. See the link in my sig about why LEDs are inferior to HIDs. Please read that thread and the other posts I linked to in that thread. I don't want to expalin it all again...

And there is NO way to convert lux, lumens, etc, to PPFD with accuracy, it's only a very rough approximate ballpark conversion, not analytical at all...I told LEDGirl all of this in her forum but she deleted it as she didn't want to look foolish.

P.S. I am the same person who you butted heads with a while ago in the AM fungi thread

P.P.S. This is my last post in this thread, I foresee arguments not based not upon science and I"m not about to get into that with you.

It's sad to say but I know more about lights plants use and how to qualify and quantify it than any cannabis Guru/author and any LED developer I have ever had contact with...and more than SunMaster apparently, the same goes for SunPluse, that guy is a dumbass and an arrogant jerk.

HTH

 

[secondtry]

P.S. That study you linked to** is one I have already critiqued and shown how it is not telling the whole story. But it is a great paper none-the-less and one I often cite when telling people about PPFD and "Pnmax" (maximum rate of photosynthesis) in terms of what we want to achieve, i.e., 1,300-1,500 PPFD.

This is a point I tried to make to LEDGirl, she claims cannabis needs less than 500 PPFD! Geeze! And she is trying to sell LEDs yet she doesn't even understand the basics of lighting!!! That is one major reason why LEDs suck.

Jorge Cervantes is actually working out pretty well for me.

 

[secondtry]

@ Mistress,

I posted again because I thought you might not post like you just did...without a clue.

lumens/lux measure amount of light, yes... & plants use light...
seems 1st have to measure amount, or intensity, then wavelengths which plants use...

Plants use PAR range photons for a vast majority of photosynthesis, PPFD measure PAR photons. It's that simple. Lux, lumens, watts, etc are not a measure of photons plants use to drive photosynthesis. Don't argue with me about it, I am merely stating facts. Have you even looked up QFD or YPF???

This is really my last post in this thread. Read the link from my sig and the other posts of mine to which I offered links in that thread (from my sig).

See ya

Mmm. Bollocks Wars. If you've done 2 or 3 grows with a modicum of success , the rest is all here.

 

[SmokinErb]

I've done more than 2-3 grows with success. I rarely ever use the books. I just like to have them...just in case. Let's look at my last grow for example. I was having Mg lockout due to pH issues. However I wasn't 100% on that, so I flipped open Jorge's bible and within 2 minutes I was confident in my diagnosis. I then followed that up with posts on Grasscity (where I was keeping my journal at the time) to verify my diagnosis. I'd rather have an opinion than say "HEY GAIZ, WHUTS WRONG WITH DIS PLANT?"

Ah well, this took a way too serious turn for me. Greg Green bible has the majority at this point in time, so Greg Green Bible it is. Thanks guys.

 

[LolaGal]

Greg Greene's Book sucks

Jorge's Book rocks

Ed Rosenthal's Guide to Indoor MJ Gardening is good too, but rather old. read it though.

Cannabible is just a coffee table book about strains and the dude smokin them.

Hope this helps a little bit.
