would go higher.. you can get away with a 5inch but needs to be the more powerful version.
eg.
RVK 125L1 342m3/hr
RVK 125A1 225m3/hr
both 5 inch, but the L1 has more power.
for a 600w would go up to 6"
also remember once you attache the scrubber the CFM's will drop, also every bend in the ducting and every metre
also if you buy UP you can always get a controller to slow it down, but you cannot speed it up any more..
hey lady j i have a question. we grew 2 RD from seed and one was topped and grew to about a foot 4-5 weeks of veg. The other is about a foot also but is packing on way more bud.. what could cause this.. same plants same light same everything.. 125w of CFL. the topped one had about 7grams of fluffyness. The other i expect to get about 15-20 and they are dense and full of res. but i planted 15 days later to keep a cycle. im just curious to know if the topping had anything with the reduction of mass. because the tops that appeard after seemed to be half of what the one cola was of the younger. both grown in fox farms soil and local nutes. 20-20-20 @ 1/4 strength for veg then 3-42-11 budding powder. bot plants were in 3liter pots. what caused one to be so much bigger then the other. Both seeds were natural not fem and were ordered from a reputable breeder.
I can't wait till I get the LEDs lol I won't have to worry about this heat stuff lol. Growing in the summer is such a pain lol. It's 102F here.
Oh wow you got the yellowing/red stems worse than me. Looks like the girls are loving the light. How did you say you were gonna know when to harvest?
Subbed, I'm in the process of getting a 12/12fs perpetual grow going too.
I also use the same nutes, including the Liquid Karma.
May I ask how many plants you plan on running? What strain(s)
I'm thinking I'm gonna go with 8 total. I've been starting 2 every 2 weeks.
I'll be following this thread for sure.
Week 5 of flowering is when flowering actually started and not when you switched to 12/12 right? Wow you're 3 weeks ahead of me, I've got a long wait lol.
Damn girl, a tent? Are you moving up to the big time...lol. with that much growing space you won't know what to do next. I think you are about right with your guess of about 3 more weeks before you harvest, and do wait for those pistols to shrival up and watch the trichs just start to turn amber and you are going to have some potent buds to enjoy.
No pics yet as my oldest for the perpetual is only 2 1/2 weeks old.
However, I did top and start to LST a lemon haze that is now 1 1/2" weeks into flower. Not much to see yet. That will be my first LST with 12/12 fs. Normally I just let them grom into 1 tall 1-2oz bud.
If you only have 4 plants, you must not smoke too much if it's a perp grow.I smoke roughly a 1/2 oz a week. So that's why I figure 2 plants started every 2 weeks should keep me stocked just fine. Can't wait til it's going full force. I just pulled out a 12/12fs LH and got 96g wet. Should be a little over an ounce when dry.
I just germed a Critical+ and an Auto Bomb yesterday, and Bubblegummer and Fruity Chronic Juice (freebie) 2 weeks ago. 2 weeks from yesterday, I'll be germing Blueberry Gum and LSD.
Then I also have Amnesia, Pineapple Express, and another auto or 3 lol.
I'm interested in seeing how the autos do 12/12 fs. Obviuosly not as well as 20/4 but they should do well.
Edit, maybe we should both start germing our Pineapple Express seeds on the same day.
Don't have a 5inch, have a 6 inch. I might have put the wrong number somewhere by mistake...but it's 6inches, 240 CFMs. If it doesn't work out, I'll probably go ahead and spend the money for a better fan but don't want to do that if I don't have to.
Did you get to witness the awesomeness that is my tent? I can remove my vid if you don't want people putting shit on your page, sorry in advance if so!
i added the side bars because there was so much negative pressure the sides were caving in too much. I also cut the screens off the intake vents because they actually slowed the airflow quite a bit. My next grow is going to change the way the world grows mj indoors though

no actually, you are right.. your cfm is cubic feet per minute
.. the one's i listed were m3 per hour...
so your 240 cfm is actually more like 408 m3h which should be plenty
6inch will be fine, especially without a can, in a tent you will have loads of negative pressure, may suck the walls in quite hard..
