So my grow area (36"x20"x60" grow tent) is infested with spider mites! I have decided to proceed with pyrethrin, in the form of Doktor Doom Botanics insecticide spray and following up with einstein oil dunk and lastly diatomaceous earth on the top of medium. I have 3 clones in coco/3 gal grow...

So I have just entered my 5th week of flower today. When I checked on the ladies one of them looks like kinda terrible. The top fan leaves are almost fluoro yellow and the tips burned horribly, the growth down lower and inside the plant are bright yellow. Nute burn or deficiency? How to proceed...

Hi all, So when I was at the hydro shop today i asked the guy for Mycorrhizae and he said he all he had Mycrose pro, a dry micorrhizae. I forgot to ask him how to use it and all it says on the tub is add 0.3g to every Gal water, do I add it into my nutes? Every feed? Also I have a carb sup to...

Hi all, So I am curious, I have a 6" inline fan pulling 440CFM through a cooltube in a 36"x20"x63" tent. However this much air movement is totally superfluous in such a small space (23.4cubic feet). So right now if my fan is on high it changes the air in there 18.8x a minute lol. Currently it...

Theoretically if I connected ducting to both ends of a cool tube and joined them with a Y connector to ducting to the fan, what effect would the vacuum have on the cool tube? Exponentially hotter? Exploding bulb? Any ideas appreciated.

Hi all, I am selling my 4x4 tent today and replacing it with a 2x2 :( Moving to a smaller place unfortunately. So I have already ordered the tent but I am wondering about lighting. After running with HID i don't think I could do it in a 2x2x4 so I am thinking LED and in particular this one...

Hi all So I have been around the block several times now educating myself on lumen,lux,cfl, fluoro, LED, HID etc So from all this I have concluded, cfls great for starting plants, Fluorescence's are bulky, LED to expensive and HID seems to be the right option lumens and penetration to dollars...

Hi all, I am in the midst of a pc grow case, which ahs left me antsy for more room. So I am picking up a small grow tent, 2'x2'x5'3", as i am only looking to do 2-3 plants at a time. So I am wondering if anyone has tried these lights, as LED i believe would be cheapest option when you include...

Hi all, checked mu babies tonight, and noticed the the leaves curling and white spots on one of the leaves, I have attached pics. From a little research I am thinking maybe water is to alkaline? so need to boost zinc? Or is this totally ok? and being a noob I am just making mountains out of...

So... I got stupid high on some white rhino X haze last night and i think I have an ingenious idea! So I have a work space of about 17.7-19", w/ lights this is reduced to 15", add a pot or party cup and i am down to 11" 12 if i am lucky. So even with a SCROG or LST that seems way to low. On top...

Hi all, So i must say I love computers and i certainly love weed, so hearing of pc stealth grow boxes I was definitely interested. I have most of the equipment already to build the case ie case, lights, fans, reflective materials. However I am wondering if the dimensions of my case will be big...
