It's been a long while since I've posted, but I do frequent RIU often. I usually don't have problems, but I recently switched to a different substrate and will eventually switch to different systems once I figure out my current problem with the coco fiber. I've been using Canna Coco fiber and...

This forum and the countless hours of research has provided me with knowledge on the growing of mj that surpasses that of the average smoker I meet. I'm sure many of you can say the same. I was enjoying a couple bowls with a smoker friend from school and he starts rambling about weed and starts...

coco fiber. i think its one of the easiest transitions from soil. i wish i had started growing in coco before i started playing around with DWC and E&F. https://www.rollitup.org/advanced-marijuana-cultivation/48979-idiots-guide-coco-coir.html

So i go to check/adjust ph on my systems to find out that my hanna combo HI98129 meter wont turn on. i go buy replacement batteries, but to no avail. i've had this meter for just a little over six months w/o dropping it or anything like that. any one else have similiar issues with this meter...

I ended up reading a bit more after searching if Canna was organic or not, and I found out how I got confused. Aqua Flores A&B, Boost, Rhizotonic, Boost, and PK 13/14 are inorganic and the Cannazym is organic. I knew one of the labels said not to use with H202, yet I was sure I had seen peole on...

I've read many posts and guides saying that using a little horticultural grade h202 in the reservoir is a good idea. Yet on the canna nute label it says not to use with h202. so is it correct to use it or not? and if so what's a good ratio and do i use it every time i "top off" the reservoir...

I did invest in that. foot long stones in each res. I hope that does indeed help out with growing shit! :) I thought about doing it that way. but as i need to move the pots to different res. i can't have them rooting in hydroton directly in the tub. I heard you can get more room by doing...

That makes sense. I do remember reading something about making sure the rockwool cube isnt getting soaked during flood. thanks for the input! anyone else have an opinion?

:leaf:hey all, I'm trying my hand at a flood/drain system. i just did a trial run with just the water, hydroton and pots. 5 gallons seems to do the trick and the water from the pump seems to reach the overflow tube within a minute or so. It drains pretty quick, but there's still maybe 1/2 an...

i recently went from a 400w in my room to the 1000w. way brighter, but the heat stays in the low 80s in the canopy and mid to low 70s in the reservoirs. i added a window AC to the room as well. that with the house AC and circulation fans seems to keep the temps stable. you just have to work...

i've not come across that guide before. thanks! i think the problem is PH. my run off on 3 out of the 4 was around the 5.5 area. where 1 of them (the worst looking) was around 4.9. I hadn't been checking the "run off" water and didn't know the PH levels for soil. which seem to be from 6.5-7...

I'm guessing there's something missing from what im giving my plants. they are a month and a half old, fox farm ocean soil, i use filtered water (from the watermill), GH Maxigrow dry nutrients at the ppm and ph levels, and weekly blue mountain organic's super plant tonic. i thought that was a...

I was considering adding airstones to all the reservoirs of my ebb/flow systems. Is this a good idea or is the ebb/flow sufficient enough to get oxygen to the roots? didnt really want to set up the pump if there wasn't any noticeable difference . :leaf:

molly dealer?! jealous. :\

i always heard use 1/4 strength nutes for seedlings and clones. which is what the label on the nutes suggests. id be worried about the 90 degree temps.

you can flower them whenever you want. its more of a matter of: do you think you'll have the room? mj grows the most during flower and in small places can get over grown.

real chill high. one that makes me feel creative and awake. very head high.

this technically wasn't my first grow. it is however, the first grow i've harvested anything off of. http://s929.photobucket.com/albums/ad138/phoenixaflame_photo/Ice%20May09%20-%20July%2009/ the light i used for bloom was a 400w hps. these were first intended to be mothers, but i decided to...
