Inda-gro Induction...

Well I finally got light burn, but only after one of the mothers reached up and touched the face of her Inda-Gro God.

Time to get some clones and cut those mothers down to a good size.

Day 28 - Northern Lights -Inda-Gro 420 w/ pontoon - 13/11



Amber pistils already?



Have not fed in over a week, just RO water until I get my nute overdose under control.

I wouldn't even call it light burn if it was touching the lamp. The glass of the induction is 200*F, so that would just be a literal physical burn.

IG are very gentle on plants form my experience. I haven't had a bad reaction yet, even when I aaas flowering with the pontoon at 12"

I was joking, leaf grew right into the bracket on the lamp. Yeah it's hot.

Look back a page and you will see mine flowering at 4".

I think I am about 4 days ahead of you 707.

My c99 and Amnesia stretched and are getting close to the 420, thanks for the info that they can get pretty close without burning. Was getting concerned.Will post update pictures of my ladies later. I do have a newbie question though that I think I know the answer too.

I did not realize until recently that PH +/- when added to your nutes affect the PPM's. So, when calculating say my 1000 ppm for feeding do I include the PPM that the PH up/down add?

Or do I ignore it because even though say it adds 300 ppm to my nutes it will not affect the plants like say 300 ppm of bloom solution would?

Thanks in advance, I enjoy this forum and you all!

I was wondering the same thing John after I read somewhere that you don't count carbs in your ppm.

Perhaps the idea is you only count what the plant feeds on. Nitrogen, calcium, yes, molasses, ph up, no.

Hopefully someone who's not a noob like me knows for sure.

Flax I will go out on a limb and say it should not get added into the PPM count. It does not add or subtract anything from the growing/flowering stages so I would assume we should not count it.

So yea, my overall total PPM is 1200 ish but 300 came from me adding PH down so in reality I should be at 900 actual PPM as far as the plants "see". Hope some folks chime in here and set me straight

What kind of system are you running?

A 10 gal Ebb/Flow system

I would consider the ph in the change if you are talking ~300ppms.. what is your medium? How often are your flooding, and for how long? 1200 seems right on par with what I've read on enf,

Something else to consider is trying to get a 2-for-1 deal out of things...

if you're slightly underfeeding and your ph is 6.2, throw in some nutes and take it to 5.8.... lemon juice, baking soda, all good 'adjusters' I personally love Protekt as a additive/buffer/PH Up


Beneficial Additives in Hydro

Sorry I do not mean to jack, but that is a good read to come back to at times. Im also going threw some of Brewer's old journals and a couple long lost Scrog threads...

Guys, I sent chaz a pm that I probably have just posted here and not of harassed him.

-I noticed IG's PAR charts have a very low curve relative to what I am used to seeing, is this related to the units measured or something else?

-How long do the 660s stay on the pontoon?

-How in the piss are people running a 420 in a 3x3? I / I <--??? (catch that? ha!)

-I did not see anywhere to purchase replacement bulbs... I understand the lifespan's supposed to last longer, but how much longer before you start seeing diminishing values? (on my apogee) or any other unit of measure (eyes... lumens, whatever)

I do love the ten year warranty, its nice to see confidence in products.

Im not in the position to buckle down and get one tonight but maybe down the road it was be a nice Cool White source. Hyroot really got me with the Even Distribution thing.. Im looking at IG's charts and I am still a little lost, but get it. I love the slight peaks, complements what both, mh and hps, are lacking..

Good luck John!

Hey Scotch,

Thanks for a very informative reply! I am not able to answer some of your IG420 questions. Ill answer what I can.

My medium is those expanded clay pellets and should be very PH neutral, this is my belief and why I use them instead of rockwool and such. I flood my 5 ladies five times
a day for five minutes, my flood tray fills very quickly (just over a minute) so this allow for about five minutes of feeding (this includes the one minute drain time). Seems
to work out as my ladies are very healthy and I do not see any signs of deficiency or over/under feeding.

I was doing that exactly as what you described, Underfeed this way I had headroom to add my PH down (GH brand). But I am trying something new and hope it wont hurt, but instead of saving headroom for PH down I am giving the ladies pretty much full strength feeds (according to the FloraNova feed schedule) and see what happens there. One great thing with Hydro is If I see negative results in my plants I can drain the tank and redo with lower nute levels.

Right now I am sitting at 1600 ish PPM because I added nutes to my PH adjusted water (had to add about 8ml of PH -) so we will see. I am also finding out that water temp greatly affects PH. My tap water here in Washington comes out very cold at 6.2 or so, when It hits room temp I see it climbed to 7.0! Learning new things all the time. So in that regard I will wait for my RO water to come up to room temp, add nutes then adjust PH if needed. Sorry to blab on, you are probably asleep my now.

LOL on the fitting of a 420 in 3x3. It wont fit. I had a DR90 ii grow tent and the 420 was too long, so I bought a DR120 which is 4x4 and it fits perfectly. sorry didn't get the I/I ?

I keep the pontoon on the 420 all the time. I did not use it the first 4 weeks during veg but now obviously am using it as I am in flower mode.

Good questions on bulb replacement, I thought I saw them online for 400 bucks or so. Not sure about the LED's thought. I talked to the company reps
when I purchased mine and let me tell you they are in the US, speak english because they are Americans and were nice as anything. What you would
expect from a quality company. I would Imagine ANY problem with the light would be dealt with right there.

I had a Lumigrow 325 light that I sold and didn't really want to let it go as I wanted to use it in my DR90 tent. But needed the $$ so off it went. Also seemed liked a
very high quality LED light.

Those Apaches look awesome, may be one in my future who knows. Like you said there are allot of things why I went the Induction route ( I love to try out non-standard ways in everything in life and not walk the beaten path) Coverage is really good and it runs warm, nowhere cool as an LED but miles cooler than HID. (I first started years ago with a 1000 watt light that would heat my garage in winter time!)

Anyway, I blabbed on sorry. But if you got the $$ I would not rule out the IG420 combo. Not cheap but I am sticking with mine for a looong time.

Thank you for bearing with me!

GL to you also Scotch.

shit you should throw up a report about the lumigrow in comparison to the IG. No to hose the lumi but I am curious what it's "capacity" was...

If you leaves are perkin' and they look happy, I would do your thing man. Just be cautious adding straight acidic or alkaline substances.

Have heard of running Flora that high, and have heard they stay around their feeding program.. which I almost find unbelievable.. but Im a DG user, and that's some potent poison.. sounds like you have a clear head.

Thanks for the IG info, their demeanor on the site speaks in it's own- good business goes even further.

Very pleasant to talk to- thank you, you give me faith in Humanity, friend. Take care!

Now what is the suggested Height vs. Coverage vs. Intensity, should IG users be treating it closer to a fluro, or closer to a hooded 4-600w/etc?

I think distance depends on the strain. I have mine about 14 inches away. They are doing fine. I have one 12/12 Fs that sits lower at about 18 inches away and its sitting to close. Hairs are burnt. No bleaching to foliage though. In veg I keep it 18 inches away. I never have seen clones grow so uniform and symmetrical. I think indica doms like the light being closer. They originate from dry hot desert climates.

I used to always keep the light as close as possible.

Since i quit Growing in in my little cab and just use the corner of my shed I've been amazed at how allowing a plant to slightly stretch can add so much to the yield

Try it if you got the head room, its like steroids or something.

I never got to grow with the Lumigrow 325 ;-(

Otherwise I sure would have a comparo between the two for sure. Would have been ideal in the 3x2 tent. Same back at you, great conversation!

My ladies @ 13 days flower. Funny the plant on the right is a c99, the same as the plants on the left! (#1 and #2 picture has the c99 shorty), picture #3 closeup of pistils, is this where the buds will grow out of?

I actually raised my lights a couple inches a little bit ago. I noticed a few cbk tops, hairs and leaves looking burnt. The lower buds are much more frosty. When I first got the lights sort of treated them like a florescent. I had them 8 inches away from the canopy. I now have them at 16 inches (exactly what Chaz told me to do lol).

@Scotch with pontoon combo I would now say treat them like an led panel when considering the distance from the canopy and treat Ig's like an hid for coverage area.

Good news.
Got word from my wifeys drs, no onkiologist needed just a hysterectomy.


So fuckn relieved I don't have to put her down!
Wooooooooo Hoooooooo!!
