I veg under a very mixed sprectrum. My primary light is a 600CMH, dropped in with 8 5000k cfls and two 4ft t5ho on the sides lol.

Be careful with that I don't want your grandma having the sheriff showing up again. ;)

How you been though bro.
CMH is the shit.. my girls love my 250 watt CMH, veg and flower. I also supplement with a couple 2700k CFL's the ones that are as big as a 2 liter bottle ;). I also have the 2'x4' 6 bulb T5HO. it came with 3500k bulbs but I just picked up some 3000k's so I'm going to try the next round with 2 3500k and 4 3000k's.

(4) OG Raskal White Fire 33 days into veg on a DR60 with a 250w MH.

I just wanted to know if anyone else has ever ran 4 plants before in a DR60? My ultimate concern is when I flip them to 12/12 in a few days how can I get more light beneath the canopy. Or should i go by some tomato cages? Any vet growing advice is appreciated as this is only my second grow. First grow was a PC case.

I did 4 in a DR80... it was hard when they started to stretch. And it bears to mention, that was 4 NOT topped... so they didn't bush out.

Yea I have a 4" inline pulling the air out and going through a carbon filter. Inline is rated at 200cfm. I have one of the lower inlet holes open also have a Clipon fan aimed right at the bulb to throw the heat around a bit.

Good evening all. Been a long while, but that's a good thing given me plenty to read.

Everyone keeps trying to go hydro, and my local shop makes his own bubbler systems which are literally flying out the window...but like you Verde, I like soil...it's the natural way. I also like to raise my light a bit for the last 2 weeks to replicate the end of summer, MJ has evolved to over thousands and thousands of years to work with the Earth, not a grow tent. That said I did have a really interesting conversation with a Moroccan the other week, how plants that grow on cliff faces grow faster then any any other vegetation because the roots lock into the cliff, and get a constant trickle of water in the rocks rather then have to work there way through soil...it's just that there is much more soil on this planet so plants have had to make the best of it. I'm still staying with soil forever. Whenever I buy weed, I can tell whether it is soil or hydro, even if not flushed...it's hard to describe.

Grazzmon, I decided this week to get a CMH when my bulb is due a change, as the first bit of spring sun in my conservatory reminded me of the two plants I grew out there last year, and there amazing taste. It was a blueberry, which I grew for 18 months indoors, and just threw 2 out in the sun for fun, and the taste difference was incredible....which I could only put down to the increased spectrum of the sun. I use dual spec bulbs at present and throw some CFL's in too, but really looking forward to seeing what a CMH does to flavour. If I don't think that it was worth the extra outlay, i'm gonna come put a foot in your ass.... or more likely get to the front door and forget what I was doing there in the first place.

Had mould problems, killing shit load of leaves, ruining feedng schedule and growth.... not good for mid flower. I have totally overcome this now, but it's fucking tears...every grow is something different fucking it up. I had to switch my extractors off overnight (2 tents) cos my wife can't sleep with the noise. Always left a circulating fan, and never had problems, but I guess my previous strains were more mould resistant. Next grow my tent is going in the loft so they can run 24/7.

I'm pretty sure that my little 250 won't cause any real heat difference n my huge loft area, especially with circulating fans, and an extractor pulling the air out of the loft. I plan to have the tent exhaust into the loft, where it will mix with the far cooler over-night air, and then this mild air will be extracted, being less invisble to the chopper heat cams. Been watching a lot of stuff on heat cams, reality cop programmes and documentaries, and it appears that they can see hot air being exhausted, but this is when it goes straight from a major grow room to the outside. What do you recon? It doesn't seem to add any real heat to much smaller sized bedroom, so I should be fine. Of course I will insulate the roof directlty above the tent ;)

I have squeezed loads of plants under my 250 in the 60x60, and it can handle it, cramped or not. The big issues I did find was air flow through the canopy and humidity...but you should be fine

my DR80 has two screened vent ports at the bottom... not the 6 inch draw string holes... they are rectangular in shape and can be velcro-ed open

Im gonna assume you're speaking about closing and opening the vents with the light cycle because you're worried about "light leaks"... I was too at first, but I've yet to have a problem *knocks on wood *

I have a new DR90, and I'm pretty sure it listed as one of the improvements as "fully removable viewing windows"...I got the impression that the older tents had covers that you could velcro open or shut, where as the new ones have fully removable covers...meaning you can't leave them open "a bit", they are either velcro'd shut, or are a bloody big open light allowing window...meaning they would have to be fully shut at lights out. This may be why sel3ctve is more worried about light leaks through his vents...sorry to butt in :)

Yup I have the newer one this is my concern exactly. They are really high up to the point I would create a light leak.

you could always try sewing/sticking a piece of thick dark cloth over the vent (after taking the cover off) this may allow more air through the vent, but no light...depends on how much you can bothered and won't to make any mods to your new tent :)
