General Cultivation Q&A

Whats the difference between "Coco Coir" and regular "Coir" (from Bunnings for instance)

Hi All, I have been readying up on Co2 systems, I have read a lot of good stuff about it. However cant really find much on the bad about it. Apart from the cost of buying the bottels, and the set up cost. I have one for grow in my room untill I move to a fully sealed ( aka insalated shipping containter). So the use of Co2 is looking like a must, just to keep the work of cutting heaps of holes in my new room down and also water tight. So I ask, has any one used them or are using them, does the cost weigh up. I have read with the right temp and hum in your room you can get 2 - 3 times more yeild, which would help with the cost of runing the room and the Co2. Also I like…

Hey. So, recently I modified a window mounted air con unit to run as a stand alone unit with twin 100mm ducting on a wheeled trolley(not shown but the same as in the first pic). 'Very interseting' i thought. I fabricated two square to round spigots that were attached and sealed to the outlet vent, and constructed a wheeled trolley for the unit...... A window mounted unit is about half the cost to buy of the portable version for the same or better BTU output. ?hhmmmm? Not sure of the power usage though? But surely a window unit needs to be mounted for it to fuction properly and efficiantly ! ?...............? Anyone a bit more 'In the know' about this sort…

I am a bit cautious about spraying my plants with spider mite killer in this high humidity. Big fan in tent atm. Just worrying about mould starting on buds if I spray in high humidity. Opinions please. Getting tired of search and destroy missions with my fingers. As not really effective. Thanks guys.

Add a florescent compont to this bleach thing; assuming the bleach doesnt denature it. I saw a design that focus out side lightwith a series of lenses, like a supped up sky light, add that Tech to this kind of bulb... you might want to replace that plastic bottle with boroslicate glass... add some bradford batts to that roof, maybe experiemnt with optical fibers to the coke bottle if the celing is tall http://dornob.com/solar-bottle-lamps-water-bleach-10000-liters-of-light/

Been a long while since I've been on the boards, had a little hiccup with the last grow and had to shut it down early. Did a Jack 33 in coco since then and everything went fine. I'm pretty much over my LED experiment now (maybe once more). Been thinking about trying out organic growing so as not to worry about ppm/ph and bottles of shit. I've been using this mix for my tomato's and they're fucking huge. Wondering if some of you organic type growers could critic my mix and let me know if this will work for cannabis? 20L Organic Potting soil - Searles Garden Soil Mix 20L Organic Compost - Searles Real Compost Mix 10L 50/50 Perlite/Vermiculite 5L Cow Manure If…

G'day guys, So recently the lower leaves of my plant have started turning yellow, and has made its way up the plant, i have read up on it and said that it was lack of nitrogen? i added a little bit of miracre grow which has a good dose in it (i know this burns plants easy so i only used a few pinches) and it hasnt helped, i changed the soil from just normal potting mix to 1/3 organic potting mix 1/3 cow manure 1/3 mushroom compost and it has got worse, im unsure what to do as theres so many mixed opions online, so i joined the ausise comunity for local advice, does the leaves turn from ph being too high or low? All help appreciated, it has started to flower also …
