My Dad chucked me some cash for my birthday on Sunday.
A new 5" Rhino pro filter and a new 5" Ruck fan coming up, happy days.

Alright Yorkie,
Haven't spoken to you yet but seen a few of your posts and you seem like a clued up guy.

Botanists discover the signal that triggers flowering
After a quest lasting more than 70 years, botanists may finally have found what one leading textbook describes as "the Holy Grail of plant biology" - the molecular command that tells a plant it is time to flower.
The discovery may help scientists tailor crops to different latitudes - an especially valuable ability as global warming begins to shift climate zones towards the poles.
Researchers have known since the 1930s that the leaves of plants perceive the seasons by sensing the amount of daylight and, when the time is right, trigger flowering by sending some sort of signal to the shoot tip. But the identity of this so-called "florigen" has remained mysterious.
Now two research teams have independently identified it. Florigen, they say, is the protein produced by a gene called Flowering locus T, or FT. One team, led by George Coupland at the Max Planck Institute for Plant Breeding Research in Cologne, Germany, and Colin Turnbull at Imperial College London in the UK, used genetic trickery to join the FT protein to a green fluorescent protein marker in Arabidopsis, or thale cress.
Green fuse
Onto this marker-enriched plant, the team grafted a mutant stem that lacked the FT gene and so was unable to flower by itself. They observed that the fluorescent FT protein crossed into the mutant stem and triggered flowering. "It's pretty unambiguous," says Turnbull.
Another team, led by Ko Shimamoto at the Nara Institute of Science and Technology in Ikoma, Japan, used much the same technique to show the same thing in rice.
Finding the same florigen in two such distantly related species suggests the mechanism is common to all plants, says Jan Zeevaart, a plant biologist at Michigan State University in East Lansing, US.
The new results are not the FT gene's first turn in the limelight. In recent years, several studies have shown that FT is turned on in leaf tissue at particular day lengths, and that the FT protein acts in the shoot tip to trigger flowering. However, no one knew whether the FT protein or some other molecule was the flowering signal that shuttled from leaf to shoot tip.
Messenger shot
In 2005, researchers in Sweden seemed to settle the question when they announced that messenger RNA from the FT gene was the mobile signal. But this week, the Swedish team formally retracted this claim.
"A guest researcher from China who had been invited to join our team manipulated the data to get false results," says Ove Nilsson at Umeå University in Sweden. The Chinese researcher, Tao Huang, who is no longer at Umeå University, still stands by his results, says Nilsson.
With the flowering signal now firmly in hand, biotechnologists have the means to tinker with a plant's flowering time to adapt it to different conditions. For example, farmers at higher latitudes might want to force crops to flower earlier so that they can mature their fruit before the first frost, suggests Brian Ayre, a plant biologist at the University of North Texas in Denton, US.

happy birthday u old bastard.
personally i would go with the 6" filter and use a reducer, will last twice as long for very little extra cost.

Cheers, I still feel 20 something which aint a bad thing I suppose.
With reduced airflow due to the bigger filter too.
I'm going to run 2 5" fans in series pulling through 2 5" Rhino filters in parallel possibly over a 600w and a 400w bulb in series, we'll see yet if I add the 400w.

if you fit a 6" filter to a 5" fan it will place less strain on the carbon in the filter, air moving slower over the carbon means it will work better and the filter should therefore last longer.
i have an 8" filter that has lasted for nearly 3 years because i have only ever run a 6" fan over it.

Afternoon boys, jus watered the ladies and stuck some supports in. Fucking pain in the arse. Next time defo getting some support rings!
The blue Thai is looking most promising. It kinda has a pollen smell to it more than a green smell

Yeah only reason it's in there is cause I killed 2 of 5 PE seeds and had to make numbers up lol. Kinda glad I did now.

are you only cooling one light or something? 5" fan and filter seems a bit lightweight especially considering the heat we are having. i must say 60 quid is a bargain, i'm sure my 6" was over a ton, i don't shop around though.

That exo and psycho a m8 has is 9 weeks flower tomoro, I can't get a hold of the cunt but he should be choppin tomoro night so when that's dry you'll have a bit of that to vape too.
