I don't think Nutriplus is junk, it's just that Canna is top notch and it made a difference in this case

If I remember correctly, he changed to Canna products which helped a whole lot !!!

I know the good stuff like Azamax, sns-217, neem oil are out like soo many others

Hi all, My friend has a somewhat large vertical hydroponic grow room. His biggest problem with this type of grow is powder mildew, so he has to use a sulfur burner. Once that is solve his second biggest problem are those damm spidermites ! What effective method can he use to kill the spiders...

Thanks Woodsmaneh. I know plants don't use co2 at night , but will it damage them ?? Purplehazin, yes he has a dehumidifier but like I said it's a large operation and it's a vertical grow with rockwool slabs up against the wall with gutters at the bottom and sprayers on top, which I guess...

Since both rooms share the same air, will the additional Co2 in the room which the lights are on affect in a negative way the plants in the room which the lights are off ????????????? He has a regular humidifier meter which show 60% at night, but he recently used a Usb temp/humidity data...

My friend has always used Co2 for his grow rooms with the fresh air fans going on for only 30 mins once every 3 hours ( note that he has a considerable size operation ). Lately he has converted to growing vertically and he's noticed he has a humidity problem which creates Powdery Mildew even...

I know someone who has used clones which where started in jiffys and then placed them in vertical rockwool slabs from Grodan which are called v-slabs. His system is a vertyical grow like " ecosystem ". He noticed that if his roots where long enough and sticking out of the jiffy that he would...

Ok, the representative from Grodan ( the one who make v-slabs which are especially for vertical growing ) mentioned that since my friend only waters 6 minutes on/ 45 mins off, some roots must be dying since they are not watered enough. He suggested to water 10 on/10 off. He also said that he...

My apologies ! The final solution in the reservoir after nutrients have been introduce is 800 ppm. The water itself is around 200 ppm

Yeah I checked the ppm which is around 800 . I don't know how much that is in TDS. He ajusts his ph with PH + -> http://www.nutri-plus.ca/hydroxyde_en.html

No he didn't , would that change anything ? I know letting it sit will only get rid of the clorine

My friend has just finished his second week of flowering in a vertical system that looks like this one -> ( http://www.hydroshop.ca/english/ecosystem-vertical-growing-system.html ) . He is using grodan v-slabs made of rockwool. He seems to have a major ph problem now ! Even if he changes his...

I can guarantee you that that plant is NOT M-39 !!! M-39 doesn't have purple color

So is Big Bud one u already tried ?? Which other ones did u try and what were u're results ? I'm sorry but can anyone tell me what autoflowering means ??? Thanks

Omg, what an active forum !!!!! I posted this thread not even 20 hours ago an I"m already on page 5 !!!! Sry to bump myself up but I would really need advice on this ! Thanks

Hi everyone, I'm looking to do some vertical growing, something like in the picture. I guess I need a indica strain so that the plant doesn't get too big. I am planning on giving them 0 to 4 days of growth before switching them onto flowering What strain do u suggest I use for this type of...

I think the ideal way would be at an Y angle but I think some people do it at a 90 degree angle ( not sure though ). Also if you are at a 90 degree angle there are more chances of water leaking after a while , especially from the water dripping down from above. If you were at a slightly higher...

Since your shoting from the back wouldn't it be better to have sprinklers in the back that shot forward instead of 360 degrees. I'm just guessing here cause I have no aero experience. And also , I think u should have your plants at a slight angle upwards. I saw a 6" in diamenter with a 4 " "...
