yellow/lime blotches on leaves?

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..
