Hey! Thank you for the reply. After some further reading, I decided to go for the following fan and appropriate filter: https://www.maxgrowshop.com/en/air-extractor-fans/759-fan-pk125-mes-420m3-h.html Seemed like a good price for it, so, hope it does what it's supposed to! :)

Hello! I have a grow box, which is about 45 cubic feet in size. I am running a 250W HPS inside it, but I will definately need a carbon filter soon. So I'm looking into upgrading my fan, as the duct-booster probably won't cut it. The thing is, the fan has to pull through the filter, and then...

Hey, thanks for the response! That looks like a good deal, but unfortunately, I can't get the one you linked shipped over here (not from the States - I'm in Europe). On that note, I found a similar fan from a different brand but without a speed controller - is it possible to add a speed...

Hello everyone! So, I have a question about which fan I should use to vent my cabinet. The cabinet itself is 2.5ft * 2.5ft * 6.5ft. The reason it's so tall is because it's basically an old closet I slightly modified. Anyhow, inside is a cool-tubed 250W HPS and with the current setup, the...

Thanks for all the replies! I do my best to see what my plants need just by carefully watching them etc., but it's a skill I have yet to master. Right now, I have decided to follow the HESI feeding schedule until the end of my first grow and see how that turns out, then I'll take it from there ;p.

Thank you for all your answers! The plant has now already been harvested, but after a little more research, I am pretty sure it was a case of phosphorus deficiency, which would make a lot of sense, as up until yesterday, I did not know that HESI recommends adding another solution of their own...

Hey everyone! I'm currently on my first grow and I am growing in soil. Throughout the whole time, ever since I bought myself some fertilizers, I've been wondering - should I be following the instructions on the fertilizer bottle or the guidelines I'll often stumble upon on the web - such as...

Heya, as promised, here's a picture of the whole plant. Had to use flash so it looks a bit washed out. Other than that, I haven't got any additional info yet, I'll be grabbing some pH indicators in about an hour though :). Any kind of help / ideas are still greatly appreciated, thank you! :)

Oh, I just remembered - my fertilizer bottle says that it will slightly lower the pH value of the water once added. Is it possible that it's turning the water too acidic? Or are these fertilizers usually not that strong when it comes to altering the water's pH value? Each day I seem to find more...

Thank you both for your answers! @Bugeye - I'll get a pic of the whole plant tomorrow, they're asleep atm. Spectrum range with my CFL could be an issue, since it's 2700K - I've read many times that it shouldn't be a problem, so I just decided to use it. I'll try turning it off though. As far as...

Hey everyone, first of all, I have to say - I've learned a lot here ever since I've started lurking about, but obviously not quite enough yet, as I am in the flowering stage of my first grow and have encountered an issue and am hoping some of the great people I've seen around here could help me...
