Will 80-85 be ok?

hi chester, depends where u measure from, i would be happy with that though. take the temp at soil level, the plant will be ok with higher temps near the light. I have mine as close as poss without touching.

the 15L pots will be ok, you should flush them when going into 12/12 and before changing to the higher P bloom ferts.

I'm doing a grow with 200w CFL at the mo. I lst'd a few plants and they are now on day 39 flower - there's a grow log wiv lots of pics from when they were little. http://boards.cannabis.com/showthread.php?t=88633

Cheers emmpey, that's reassuring.

I was previously measuring temperature on the floor, then moved it level with the canopy. I will move it to soil level and see if it drops some; it is a small area though and I did notice a difference when I added the blue light in with the red. Both my lights are 200w so I've got 400w, in a small area, which I'm sure is responsible for the increase. Anyway, I just wanted to check that growth would be ok at 80-85. Thanks.

I'm glad the pots will be ok. I didn't want to transplant now really as it would have been messy. If I ever do this again, I think I would use maybe 20-25 litre pots with an inch or so of some medium/light gravel in the bottom, to help with drainage.

I've already started the 12/12 and bloom ferts and didn't do a flush prior to switching - no harm done I don't think.

Will post some updated photos when this week has passed. I'm noticing a slight change in the plants but not quite as scary as I was expecting following some words of warning (above)...I'm assuming it will just happen, soon enough!

Thanks again for the advice. Nice grow log as well, by the way.

Week 2 of 12/12 and week 12 overall. Thought I'd post a photo update.

Still not been overwhelmed by "growth" yet, but they are bushing up at the top, and the top of each of the main branches. Still looking nice though.

Two weeeks in Chester? Patience young whippersnapper!

get that other light horizontal and lower them too - now that you're in flower you really need to get as much light as possible onto those buds. any buds more than 10" from the light will not yield very much.

Cheers for the advice again emmpey. I do have another hood, so I'm going to use it although it's not suited for the envirolite bulb which hangs rather awkwardly in it. Anyway, I'm sure I'd probably get more out of the light if it were horizontal so I'll put that back in (it's what I used for the veg stage anyway).

I think the photo's a little misleading with regard the height from the plants...at most it's 6-12" away. I take the point though; the closer the better.

Noticed a difference in the growth today so I think it's picking up now but yes, Weedhound, I must learn to be patient! lol! Like a kid in a candy store.

Just a word of warning about "hanging" envirolites. On emmpey's advice, I decided to take my light, which was previously hanging vertically (see above photos), and put it back into a hood, to hang horizontally.

Anyway, I discovered that the plastic base of the light was ROASTING hot (couldn't hold it in my hand) and I'm glad I caught it when I did! It appears that, due to the way the light hangs, all of the heat rises upwards (yes, I know, envirolites aren't meant to be hot - but they are, take my word for it!).

This heat passes directly over the plastic base and it appears that this could be quite a fire hazard. To test it, I decided to touch the other light base (red spectrum) which is hanging horizontally in a hood. Yup, it was as cool as a cucumber.

So...I would strongly advise you NOT to hang envirolite bulbs vertically. ANY bulbs for that matter. Even if you've got ventilation etc, it won't matter because the heat rises upwards over the plastic base, thus heating it up.

Sincere thanks emmpey - you may well have, inadvertently, prevented a fire there! Much appreciated.

good call chester - I have seen them hung vertically as supplemental lighting but with the 'ballast' (I don't know what you call the starter gear on a CFL) at the bottom.

I think it's a bit of envirolite hype regarding temps, although the bulbs do stay MUCH cooler than HPS, the overall heat output is not much lower.

here's an article by ed rosenthal about evirolites, see what he says about heat output.

Hi again.

Photo update for you all. Week 3 of 12/12 now, and week 13 overall (from seed).

Really starting to flower nicely. Not very dense so far, but it's early days.

You'll see the problem I have with my old reflector and the envirolite. Hangs really unusually, and looks like it's going to break, but it's sound and is much cooler than hanging the light as I had been doing previously (thanks again emmpey).

Would appreciate your thoughts on progress so far.

One thing I've noticed...since I removed the males, there is hardly any odour. Not that I'm complaining, but at the same time I really like my greenery to "honk". Is odour particularly important at this stage, in terms of strength?

Thanks again for any advice offered. Hope you enjoy the pics.

I think the oder doesn't exactly tell the potientcy of a plant. I believe it does however tell the strain. My plant are almost 5 weeks in flowering in My CFL cab. And there is very little oder If anything they smell kinda Rank. They smell like a barn, Or like the organic materials I feed them.

I only have 2 plants though... Yours are looking really nice tho duder..

Sweet grow. Never seen the big envirolights in action before. Can't wait to see the final results! Good luck.:smokin:

looking good there chester - i find they start honking more when the trichs appear :) give it another week or so and you should start noticing the good stuff on the bud leaves.

Hello again.

Photo update for you all, as promised. All seems to be going well.
Week 4 of 12/12 and week 14 overall.

They are taking a lot more water/nutes now, and are starting to plump up at the top mainly, although the flowers at the bottom have started well, despite being further away from the lights.

I've noticed some yellow speckles on one of the plants, so I am going to flush with water only, next watering. I'm not majorly concerned about it, being 4 weeks into flowering, but I'll have to keep an eye on it.

Space is becoming a major concern really. Every time I'm in there and am moving things around (turning plants, watering etc), I feel like it's all very heavy handed. Leaves intertwine and are in danger of snapping branches, so I'm having to go very carefully. Clearly the more space the better. Some of the pictures on here though it looks as though people are squeezing way more than 3 plants in, in much smaller spaces, so maybe I have a lot to learn in terms of pruning, LST'ing etc, in order to get the maximum yield from the minimum space.

Anyway, enjoy the photo's. Comments, advice and suggestions all greatly welcomed. Thanks.

Chester

They're looking nice :)

Dont feel bad, I physically can't get to the whole backside of my plants at all. I wont see back there until harvest.. So you're doing well!

Thanks MisterE.

So it's ok to just leave them growing; that's good to know because I was getting worried about damaging them any more than I have done already. In an ideal situation it would be better to turn them though, yes?

Because they are potted seperately, I lift them right out of the room when watering, although I do have a tray set up underneath the pots to catch any run off. I've pretty much been flushing them every watering (in the bath!) just to eliminate any potential problems. Seems to be working.

Anyway...can't stop looking at them every day now...sniffing the flowers, staring at trichs. The whole experience, so far, has been fascinating, good fun and, with any luck, will have a really nice ending! :rastasmoke:

Cheers for the reply. Feel free to post a pic of your grow.

Oh, yeah if I could rotate my plants I'd do it every day. Mine will be very uneven at harvest with some parts ripe and some not so much. I might try to stagger the harvest if it seems possible at the time. I'm not too picky though so we'll see.

I'm sorry Chester, what was that you were saying about space concerns?:D They look terrific btw!

hey chester, the trichs look nice for 4 weeks :)

Hi. MisterE...can you explain about staggering the harvest? Won't it all "ripen" at the same time? I'm not too picky either to be honest, but if there was a way to take off the large top flowers (without killing the plant) and keep flowering the smaller buds below, which would get more light with the larger buds removed, then I'd consider it.

Yes Weedhound, only three plants but the room is full! Lol! You were right about the growth although, maybe because I'm in there every other second "checking" stuff, I haven't noticed any dramatic growth, day-to-day. A "watched pot never boils" I guess! Woah, I made a joke! :stoned:
It's actually interesting looking back through my post here, at earlier photographs, to really appreciate how much they've come on but yes, they are monsters now really!

Emmpey, do you know how long I should flower Northern Lights for? Reading posts here it seems 8-10 weeks flowering is about right, in terms of optimum strength, although I'm quite happy to have a little more quantity rather than strength. Really nice crystally looking at the top though, all three plants.

I read that I should check the trichs to see if they are going cloudy. If 50%+ are cloudy, that would be the optimum harvest time, yes? Does it really matter though? Like, after 9 weeks flowering, I could just decide to pull the plug on them and still have some pretty good grass?

Thanks again for all the advice. Slight yellow spotting appearing on one plant tonight so will probably post a panic pic tomorrow. I had thought it was only a couple of leaves but on closer inspection it apperas to be affecting the whole plant. Update to follow...

Thanks again.

As promised, my panic pics about these cream/yellow flecks which have started appearing on one of the plants. I've noticed it has gotten worse the last couple of days. Anyone know what this is?

It's not on any of the other plants, and they have all been getting the same treatment.

Also enclosed a couple of updated pics of the room.

Would appreciate some advice on what that problem might be. Thanks again.

hey chester. dunno about those yellow specks, i aint had that one before - check under the leaves too for signs of insects. regarding flower times you should expect to go at least 2-4 weeks longer (yeah shocking). give it two weeks longer just to get ripe (i.e. mostly cloudy) - then add a couple more weeks depending on how much amber you want - always watch the trichs though ;) more amber - more couchlock. I aim for 40%-50% amber but its a personal preference thing.

Hi. Sorry, been away for a week or so, so haven't been keeping up with my photo updates.

Here are some pictures taken at week 6 (of 12/12), although I'm at week 7 now.

The yellow spotting was either nute burn or a deficiency of some kind. The closest picture I could find on the net:
http://www.icmag.com/gallery/data/500/1134calcium-1.jpg

I'm sure I have a calcium deficiency with this one plant. It certainly isn't bugs of any kind, firstly because I can't see anything and secondly because neither of the other two plants have been affected.

Anyway, I think it's too late now to try and resolve this issue. I hope to be cropping them within 2-3 weeks tops! I'll post a pic of the sick plant next time.

Anyway, here are some pics of week 16 overall, week 6 of 12/12. Enjoy.

Hi. Here is a series of photos showing how the yellow spotting has developed on one of my plants. Also attached is a room update, week 17 from seed, week 7 of 12/12.

Should I remove the seriously damaged leaves or just let it grow out now, considering I'm only going to be at it for another 2-3 weeks at the most?

If I should remove them, where should I cut them? Where the leaf branch meets the stem of the plant? I don't want to "hurt" the plant or invite mould/bacteria into a "wound" if I can help it. Would appreciate some advice on that.

I have some questions about harvesting too. Is it possible to part harvest? MisterE suggests that this is possible, but again I'm not sure where I should be cutting and what I should be cutting. There are lots of small buds around the base of my plants that could certainly do for being in direct light, closer to the bulds.

When it comes time to harvest is it best to just cut at the base and trim everything from there?

Also, with regard possible yield, when I look at them and envisage all the leaf removed, it doesn't look like a great deal of "bud". What should I expect from 3 Northern Lights plants?

Also, when to harvest. I've read about waiting for the trichs to turn cloudy/amber, but not having looked at trichs before, should I really be checking this every day? I've got a 30x magnifier, and the trichs look amazing but in different areas of the plant they look different. Advice would be greatly appreciated again.

Thanks for all the help...I'm hoping this turns out to be a nice crop that keeps me going for a good few months at least! Another 18-20 weeks would be useful anyway!

Was it something I said? :(

Chester

:hippy:

Yes it was something you said.....what did you say? You will have more bud than you think when the time comes Chester. I dont really know what those spots are on your leaves though; are they spreading? If not I would probably try to limp through but if so.....well you may as well just cut them down then and send them to me. Once I have studied them I will let you know how much bud you would have had.

As for harvest, you can harvest the more mature buds and leave the others to grow if you want. Cut the branches fairly close to the main stem and make your cut as clean as possible. I usually leave about an inch of branch because when I try to cut at the stem itself I always end up stripping off some bark. Then I take a dab of Serenade and put it on the "wound" just once like a voodoo charm agains mold etc. If you harvest the whole thing then yes, I cut them at the base and break the larger branches down to workable. I try to keep the branches in a pattern that when I hang them upside down they have good airflow between the buds for quicker drying.

Lots of people are different when it comes to when their plants are done. I like my trichs mostly cloudy with a little amber....too much amber makes too much sleepy and not enough fun for me but to each his own. And yes; towards the end I check them every day. How can you not since they are so neat to look at?

That spotting.....it's not spider mites is it? I have not had that problem with my plants but I know a lot of others have. It is definitely not hard to find a better mind than me on these forums who will know.

Hi Weedhound....thanks for replying! :rasta:

The pictures in my last photo post show how the spots progress on the leaf. First it's small spots, which spread across a leaf. They then seem to join to make the leaf yellow, and then the yellow starts to brown in the middle.
Lol! Yes, I'll send you the plant and you can "study" it for me.

I think I might part harvest the plant that has these problems. If it was spider mites wouldn't it be affecting all of the plants? This is only affecting one plant, and you can see how close together they all are.

The problem with the trichs is that they already look a little cloudy in places, in some places amber, in some places clear. Should I just go for it? You are right though, I can't resist a peek every day now! :stoned:

Anyway, I'm "out" at the moment so I may consider swiping the large bud on the damaged plant and see if it allows the other buds lower down to grow. Should I remove the yellow/brown leaves on this plant too?

Thanks again for replying. Appreciate the advice.

Chester
Nashville

I usually check the buds nearest the light....I try to go for mostly cloudy, like 70% cloudy and maybe 20% amber. Maybe 10% or less clear ones. I try to check the same bud or group of buds every day to note any changes. Generalizing is the best you can do in my opinion. You may want to try snipping a few branches here and there with different trichs on them to try to help you decide what you like best. Just remember which one is which after you have dried them---that's the part I forgot when I did it. It will also help you by letting you do a partial harvest and letting the smaller buds get some extra light while you "test" the others. :)

I am not liking the look of the spotting on those leaves though. My very first guess would be spider mites.....I have seen them on some of my outdoor fruit trees although never in my indoor plants. Might be a good idea to post a new thread in this forum with some photos of those leaves.....they are good photos so someone should be able to pin it down for you. Why they would only be on one plant though seems weird to me. Of course it could be something else altogether so it would be good to get other and wiser opinions. You said you have a 30x mag.....can you look at the back of the damaged leaves and see if you see anything?

I probably would remove any damaged leaves if you can but now I really am starting to be curious as to what that is. I will check back soon and see if you have been able to dig up any answers etc.

Talk to you soon. :D
