The Cannabis Encyclopedia - Jorge Cervantes

It covers everything you’d need to know. It also has an illustrated diagnostic section, which for any novice grower is an invaluable resource (ie without needing the Internet)

A brief overview of the issue or curiosity I’m having is usually covered which I can then use to focus my attention toward a more in-depth resource.

I also recommend: Growing Elite Cannabis - Ryan Riley

I have an older digital version of this book, it has been republished so I’m sure they updated some of their information but this tome (516 pages) has a lot of good information. It’s easy-to-understand and has tons of good images to help illustrate the techniques and processes for all the major. It’s pretty costly (~$90-$100), but depending on your level of interest it could be a great investment to your growing knowledge.

Happy Growing!!

Apera Instruments makes very very good ph pens. I’ve had mine for many months and I’ve calibrated it 2 times. I didn’t even need to calibrate it the 2nd time. I just wanted to see if it was off after a couple months, but it was still good! It’s still correctly calibrated right now, which has been another couple months since I did it last

I know some people use the cheap 15-20$ Orange and yellow ones amazon has with some pretty good results. I would personally spend a tad bit more and get one from Apera if you can.

Here’s the one I have: Apera ph20

I currently am running 3 different LED's.

Plilzin 600w from Amazon.- these were my first LEDs and although they are ok, I would not recommend them based on the availability of better ones at a similar price point.

Main lights are Besva 1500w. Love the light, very powerful, low heat.

BESTVA 1500W LED Grow Light Full Spectrum Grow Lamp with IR&UV for Greenhouse Hydroponic Indoor Plants Veg and Flower

My littles start and grow under this lamp. Amazing little unit. Deep penetration which brings great growth.

This is exactly what I was hoping to find on here! thanks! I spent an entire day looking up pH pens but calibrating it every time with the packets (which only came with 2 per order) seemed like a hassle and some people said they werent as accurate as they would like. I found the following:


Would this be fine? also for the vial, is there a specific amount of water it can hold (can it hold enough for 1 watering sesh) or is it small and would i just have to keep adding water into the vial to adjust pH until i have given the plant enough water.

If this isnt good would you mind linking the one you use. Thanks again!

See if this link works:

Also, definitely get a fan speed controller and set that baby at the lowest setting. These guys can really go and you're not gonna need all of that CFM for such a little tent. The key is that these fans can create higher pressure (to overcome the resistance of the filters) at lower CFM (to not turn the whole room/closet into a wind tunnel).

If you then hook up the fan to a temperature switch it'll only run when the tent gets hot enough. This will save energy, create less noise, and also avoid creating temps that are too low at night if you like your apt to be cooler while you sleep.

This is all way more info than you asked for but it'll be a really nice, easy system and it'll work with any size tent if you decide to go bigger in the future.

The Fungus Gnats are a product of overwatering, get a small fan to blow across the top of your soil and across your plants LIGHTLY. I put a layer of Hydroton or sand on top of my soil to cut down on the fungus gnats. You could also try adding beneficial bacteria, Bacillus Subtilis for example will kill fungus gnat larvae. Roots Organics soil comes with them 100% of the time in my experience and I throw some microbe teas in with some Subtilis, they generally clear up within a week of the first treatment for me. Here is a link to a product containing pest killing (and plant helping) microbes.

I add some directly to my soil before I put my plants in. Also add 1/4 to 1/2 teaspoon per gallon when watering. You will likely experience an explosion of root growth after using this product or something similar (Great White is another good one but more pricey). Hope this information helped. (Also the fungus gnats will probably do nothing to your plants other than annoy the shit out of you when you're taking care of them)

Your best bet would be to look at "quantum board" style lights. They are boards with many small LED diodes etched on. If you decide on options 2-5, Makes sure to get a 240w board or higher for your intended grow space.

Here are some options off of amazon (1-4):

  1. Mars Hydro ts-2000, 3.5x3.5 coverage
  2. Spider Farmer SF-2000
  3. If you're good at DIY. If you can wire stuff up yourself.
  4. If you're really on a budget, you could get 3 of these
  5. If you're familiar with Alibaba and fine with paying high shipping costs from China, this is your cheapest option out of all. Pre-assembled boards are more expensive, but if you order the non-assembled ones (DIY), it is much cheaper. Kingbrite is a trustworthy brand on Alibaba. Assembled or not, Alibaba will be the cheapest out of all of these.

    Edit: sorry for all the formatting issues. That’s what I get for switching between mobile am desktop.

This is the PH tester I ended up purchasing. Middle of the road with lots of opportunities to upgrade. Apera Instruments AI311 PH60 Premium Waterproof pH Pocket Tester, Replaceable Probe, ±0.01 pH Accuracy, -2.00-16.00 pH Range

Your advice on the soil composition has been super helpful. I just ordered some additional perlite as I learned my mix is very light on non organics for airspace. I didn't even think about this until you posted. I ended up purchasing a 1 gal sprayer with a low pressure sprayer I'll post pics when it arrives. After some reads on other posts, I makes a lot of sense for reach and east of gentle watering (again, I never thought about this!).

Can you tell me a little more about recharge? I'm really unfamiliar. I'm pretty versed on compost teas but is there something to consider more into flower or late stage pre flush that has worked well for you? Again, I'm trying to do an entirely organic grow if possible.

I bought a Lumens meter for $20

And I use it more than anything.

I found that PEAK is 20k lumens is max for a full grown plant and 19k for sprouts.

Comfort zone is around 17-18k (peak). Every inch drops by 1000 points.

But, with under powered lights you have a second problem, radiation from the LED output device.

If you have to push the LEDs to close to get the 20k, you'll burn the plants very prematurely from heat from the board and some other radiation source that I am presently on a quest to get the exact physics on.

If you got outside on a partly cloudy day you'll pull 90k lumens from The Great Photon Emitter in the sky.

I have a high powered device, probably like what you ordered as a main flowering LED and its almost 2.5 to 3 ft above the plants and comfortable handles 2 plants. For a 3rd, I am squeezing and rotating a lot.

I dangle a lower powered 80w at a side angle to 'fluff' the top and middle from a different angle with photons. Never exceeding 20k lumens at any point on the plant.

I might still be a little to high and need to back my lights off some.

Remember, LEDs are just laser beams with a borked direction

I remembered I have one of the most popular growing books as an eBook. Here is a link to download Ed Rosenthal's Marijuana Grower's Handbook. If you feel conflicted about pirating books you can buy it from Amazon also. The other really popular growing book, Jorge Cervantes Marijuana Horticulture, can be found here.

If you mean 4 x 2" footprint, what is your height? Because with a little plant training, that area is begging for a t5 light. 4 x 2 isn't that big of a space and you'll only be able to do about 2-3 good sized plants.

For that size space i'd use an 8 bulb, 4 x 2 t5 lamp with 64 or 6500k HO bulbs for veg. It will help keep plants short and good training will make them fill up nicely.

For flowering I'd switch to 2700-3000 k HO bulbs if my training went well (screen, lst, wtfever) and my plants were short and full. If the plants didn't train well and have multiple layers of flower nodes, i'd switch out to a 400 watt hps or a GOOD cobb led lamp.

but that's just me.

u/DiYRDWC · 1 pointr/cannabiscultivation

I have a T6 and a T4 with the manual speed contoller, dead quiet even at mid high speeds and it moves a ton of air. Love both of them, mine hang on bungee cords to absorb any vibrations.

The fancy controller will spin up the fan speed relative to a temperature set point and possibly humidity. Just make sure to set the fan speed to the maximum in manual mode before you set it to auto, if you dont and the fan needs to ramp up to a speed higher than the level set in manual mode it will supposedly lock out, and that was part of the reason I opted for the manual controller.

That said I did my reasearch 5-6 months back, they may have fixed the issue, and it also did not seem many people were effected by the issue, so the fix of setting the fan speed to max before setting it to auto may work.

u/no-mad · 1 pointr/cannabiscultivation

Harvest now. Try again for next year. I think it is the heavy dew that sits on them all night till the sun hits them. the dew just gets down into the buds night after night and causes the rot. I think in the fall it is best to cover with an agricultural fabric like remay.

u/ruckustata · 1 pointr/cannabiscultivation

I use the this Apera I bought from amazon.
Have had it for a while and hasn't failed yet. I follow manufacturer instructions on storage. I check the calibration once every couple months and it hasn't needed calibration in about a year now. I bought extra storage solution KCl from amazon as well.

u/Aaron8001 · 1 pointr/cannabiscultivation

too lazy to look for the model number, so here are the amazon links

Meizhi 600w

Phlizon 600W

the meizhi is definitely better for sure

u/tunage · 1 pointr/cannabiscultivation

Pick up one of these. I use it all the time.

Mine is the pretend 2000w version and for me, 1100k lumens (about 3.5 ft) for sprouts and then slowly implement to about 2100k lumens (about 1.75 ft) for full growth flowering. I'm comfortable with 2 plants as long as I rotate a lot.

You're lower powered and might be tempted to lower to much.

LEDs are exact in their spectrum (end abruptly) unlike incandescent which bleed across the board. But that makes them more efficient in the spectrums you want.

LEDs are basically low powered lasers with a borked direction.

Your eye appear to see less light, even though just as much radiation is hitting your eyes (and those sensitive leaves).

Don't trust your eyes, trust the $20 gizmo and the coloring of the leaves.

u/lampchairdesk · 2 pointsr/cannabiscultivation

I agree Mars Hydro is a great tent for a great price, you could get a vivosun if you want to save 35$ or a gorilla tent if you want to spend 335$ extra but I would go with the Mars Hydro.

u/RabbitNightmare · 1 pointr/cannabiscultivation

Chances are you are WAY to close and definitely not too far away.

Those sprouts are trying to get their head in the dirt, not reach for the sky like a guppy on its last breath.

Find the point they are reaching for the sky (about 3 to 3.5ft or higher if your lights are stronger). Then lower a little at a time (every 2 days) until they level off a little.

They should always be reaching just a little at the tippy top. about 10 - 15 degrees.

Also, if your leaves turn too dark too quickly, is another sign of roasting your bud (to be) way to early.

LEDs like lasers. are a specific wavelength. Your eyes are uses to many colors coming from the sun and incandescent bulbs. About half the spectrum is missing from LED (so it can be more efficient in the ones you want), so your eyes 'think' its not as bright, but it is. At least in photon impact and heat generated is concerned.

u/Leo_Stotch · 1 pointr/cannabiscultivation

There are a lot of good online resources out there.

There’s this one, this one, and books you can buy or possibly find at your library.

u/OakIsland4J · 1 pointr/cannabiscultivation

In my experience you dont want to waste your money in a cheap light, they are junk and you will be wishing you had bought better one instead of wasting your time money to have a poor yield.

If you are looking to learn cheaply and dont care about results, then a cheap light is okay and can be used to for early veg later on.

If ya want a cheap light go for this one, it a better deal... again 230-250w draw

Edit added link I forgot

u/mageman314 · 1 pointr/cannabiscultivation

Yep, I had the same thing happen on my first grow (on my 3rd now). It's stretching due to not enough light. You can basically ignore the recommendations of the grow light manufacturer's as far as distance above the plants -- they seem to always err on the side of caution. I bought this lux meter on Amazon for about $20:
I've been keeping the light intensity between 10K - 20K lux for seedlings and that seems to work for me. Then gradually increase.

u/FungalFanatic · 1 pointr/cannabiscultivation

200w actual draw, full spectrum, QB. This is the light I bought in case you wanted to look at it

u/MrTyTheCannabisGuy · 1 pointr/cannabiscultivation

Lockout, likely mag not being on the take correctly.

Recharge to start. I stand by this stuff for any uptake/lockout issues if you know you have a balanced feeding profile.
