(or pie times the radius squared - BEDMAS brackets exponents division multiplication addition) your way makes it way more complicated, plus its less useful information, he's clearly asking about an active intake and wants to know what % his intake fan should be of his exhaust fan.... also I'm...

1/4-1/2 of the exhaust as intake when using active intake. as a rule of thumb. another uel of thumb is dont use active intake. theres a few exceptions. if you don't have mnore than one source of fresh air for example. but generally allow physics to do the work for you. its free.

Finallly

6 weeks or fill 0.6m² is a kind time though

Well obviously, but how much square footage/meterage is it and how many plants? I run 1²

whats ur veg time though

I can't seem to upload any images but let me put it this way. I can't fit my.canopy.inca single photo ;)

Pretty sure that's the question I asked. When they stop strrtching. But this just leaves smaller bud sites. I pre veg longer so don't get asuchcstretch Why won't my images upload hmmm..

but you're arent giving me any useful advice.or telling me anything at all. Like what are the fundenments you speak of? And I'm more.asking, does.it hurt yield.if you tuck to long. Answer (from experience) pretty.kuch all tucking after flowering is insisted should.be just to lower the head you...

i came up with the simillar idea on my own. took me a bit of experimenting to figure out the best way and since my vent output is very small i blow into the box not the filter, then suck out the filter and vent outside. this is because of the heat needing tobe vented outside. i originally used...

act actually that is optimal because high pressure goes to low pressure naturally so it actually just reduces the overall resistance of the filter and causes the air to be forced out, i find it uses the filter more evenly but your fans die alot faster, and good fans are expensive, filters are...

That's a bit over kill 600W will do per plant. Better have more lower wattage sources of light. Imo atleast. Use the extra 400w to suppliment with a CMH or something. A mix of light gives best results I find

Know this is old but pretty much everyone of my mates that grows achieves that. That's the goal atleast in my town. Lights are a 600W MH then. 600W hps per plant so 9 in a room with 9 plants so 1 per m² ina. Scrog. Need 50L or bigger pots think 15 galleon. DWC or standard hydroponics (soil...

old as fuck threat but im a pprofessional so im going to post this anyway there is 2 ways to cook a steak. (if cooking rare/bleu remove from refridgerator atleast 30m prior to cooking) 1.get a csmoking hot pan, I literally mean it should be starting to smoke its that hot. 2. pour some oil over...

saw you ran a strawberry couch and mentioned she was finicky, ive got 5o f themany advice you could give me about teh strain?

We're I think alot of you are forgetting if your not using RO water you should check the pH of the water your using. If it's to out of range you will have issues with nutes that are pH sensitive. But you always have to check after adding nutes to ensure it is still in correct range. MY water...

The 24 hours darkness is to Ensure that they have a night long enough to trigger the hormone switch. 12 hours is light is basically the border (is like 13.5 I think?) between the different cycles so there's no doubts about them initiating flowering at the switch. People claim that flowering...

No just more like say as a % of final stretch

What signs do you use to guage when to stop tucking? Is it when they stop becoming uneven? Cos Iu do wanna let them stretch a lil right? Has anyone tried using MH and switching to HPS when stretch stops?

Sooo just wanted to ask something if anyone is still here. Soo basically you wanna veg till full. Flip and allow vertical growth pulling back and heads that jump up above the others? Like is what your aiming for that all bud sites start at the canopy and go vertical from there?
