Thanks guys, I sat in there this morning and had my morning smoke and coffee just looking at her.
Then I looked a max... There could have been 5 of those... Oh well.



Hey Slim, I think that would do it as long as the plants where small enough. Anything over 2 feet I would want a little more light.
You been growing in a greenhouse for a while, let me ask you a question. Do your temps stay about 15° higher then outside? How do you keep yours cool?

hey mate thanx for your reply. in over cast days and at night the temps are few degress hotter inisde the greenhouse, but on the days where the sun is hitting the roof its deff 15d celcius or more inside, i have a couple extraction fans on the roof to suck the hot air out. my crop isnt visible from the road or to neighbours so i can really open up the doors to let the air flow in. but in the middle of summer it has gotten up to 60degrees celcius inside with no ill affect, it sounds hard to believe but it could be the strain or the fact i grow in coco so i water from 4 to 6 times a day so maybe keeping the roots wet and cooler makes the diff. i was actually considering puting up a shade cloth on the roof i can wined on or off just to use it between 12 and 3pm on the really hot days, but since i cant see any problems i didnt bother.

Thats sounds good. unfortunately when I open mine up I get a bunch of bugs. I didn't wanna go with an extraction fan on the roof cause I was thinking it would block the sun. On the other hand like you say a shade cloth. What to you think about a second layer like clear plastic over my roof like 6 inches away. Do you think like 6mil plastic sheet would allow enough light but stop heat cause air could go between.

24 hours in water then 24 hours in the cube and bingo!
We got 4 out of six up.

Train on the left and bubba on the right.






I started three of each.



Here's the TD, I got about another inch of of vertical growth over the last 24 hours.
At this rate I bet they double in size in two more weeks.






They responded well to 500ppm Flora Vida grow and hygrozyme pH 6.5

I think the plastic over the roof will let enough light in, in the winter i double bubble wrap my greenhouse and my girls still do really well. I no the company i bought my greenhouse off redpath.com.au under greenhouse accessories they have there twin skin grenehouses with the gap between each layer. there is a device u can run and attach it to an aircon and it pumps the cool air in that layer keeping the temps cooler.

Thanks Leeroy, I took a few minutes and Googled twin skin. I see what you mean with the blowers.
I wasn't able to find any documentation as to how much cooler it get's it but Looks like it will help.

In the afternoon I get a breeze that comes from the back side. I'm gonna see if I can work with that by installing another layer of roofing panels on front and back about 4 inches above the original leaving a gap at the peak and open on the sides so air can blow through.

When there is no breeze the warmer air between the panels will be able to rise through that gap I mentioned. That combined with a couple other modifications, drilling holes in the wood spacers or bird blocks between the rafters and screening them. Also mounting a screen on the roof vent and keeping that propped open.


Heres a sketch of what I am planning for anybody to comment on.

I love it, great idea. Dont forget to maybe open up some airflow close to the bottom. Cant remember how much of this you may have done already, or how possible it is with your setup. But the air coming in from the bottom should help.

Cool, ya I think thats what Im gonna do. I got airflow through that big fan running under the water shed. Thats 1650 CFM but screened like it is its about half that. But its at ground level and at least 10, probably closer to 15° cooler air. Then 800 CFM exhaust on the opposite side at about 6 foot. I suppose I could reverse that if I need more intake... and I still got the A/C.

Forgot, I got some pics of the Silver Jack.
This is the second half of the Spring Harvest. Well almost, I still got that one Master Kush left.










These girls dried much faster then the first batch. I don't have a snap yet but I can feel it. Didn't even need to separate the branches, kept them whole. I removed all the fan leaf but left a few leaves by the buds. This will be much easier to finish trimming.

Great harvest!! I forgot about that big fan, your right you probably have enough low intake. Then again you probably shouldnt sweat that heat that bad as it really didnt seem to affect your grow much last year. More so it was the dew on the walls/roof and the buds getting wet because they were overgrowing the area.

Thanks man, Yea these girls did pretty well. One was much heavier then the others, the second one down the line. Shouldn't be much longer and I will have weight. You got me thinking about this heat issue. If I were to think this summer will be the same as last then yea, I would agree with you but I don't. What keeps us from hitting 100° temps during the summer and fall is an onshore breeze. It comes through the golden gate then fills the valley. It creates a marine layer of cold air and fog that burns off in the morning but keeps temps around 85° during the day then like clockwork in the afternoon we get another one from the south, my guess is it come up the valley from Monterey. But it all depends on the the way the wind is blowing. When we get off shore breeze then we get baked. I've lived in the so bay most my life and usually we get two or three weeks of this towards the end of summer. It can happen any time though and last about a week. Last year we had a pretty consistent on shore breeze but thats not the norm.

This dual roof thing would not be easy to do and without a constant air flow like a fan who knows how much it will help... if at all.
Maybe it should just drill the holes and open the vent, screen them and see what that does.

Believe it or not I have been told I over do things. :wink:

Thanks again for your input.

G-13 smoke report.
Well, I'm sorry to say the g-13 wasn't all that. From what I read about it the stuff it sounded like the best Indica strain out there, I don't know, It pretty much like the Blueberry. Smooth smoke, average strength body buzz. Good daytime indica I guess, as the buzz doesn't last but an hour. Thats my experience, maybe different for others but I gotta add some bubble hash to this to get where I wanna be.

Whats the strongest Indica out there?
I got Mazar seed I've had for a couple years now. I haven't grown it cause its not feminized and I only got five. Maybe I should grow that out this summer in the cab, separate and pollinate one female to get a buncha seed then when I grow those I can just toss the males or collect pollen and cross my own... yea, I got some freebie fem seed from that last order to fill the cab back up with once I pull the males, I can start those too... I'm liken the idea. That would keep me busy while the girls are growing in the greenhouse this summer. Shall we go hydro or soil?

Hydro for yield or soil for taste, looking at what you pulled last summer I'd go with the earthy taste that you get from soil as yield is certainly nothing for you to worry about lol

Id also go for the soil as well mate. It's messier but like ^ said, not like your growing for profit either, but just for some primo weed, taste is a criteria that falls into the primo weed category. Do it cruz!
