one of the biggest reasons people get so much nute burn with AN is because they use a different ppm scale. AN uses a NaCl ppm scale, which is your EC x 700 = ppm. default ppm meters use EC x 500 = ppm which is also known as TDS and is based off KCl. Mother Earth Tea is a base nutrient or...

if you want to NUKE them and make sure that none of them come back, use floramite. its toxic shit though and you want at least 4 weeks between application and harvest. floramite kills spider mites and their eggs and should be sprayed on the bottom surface of all the leaves. neem oil only kills...

yes co2 allows warmer growing temps but heres the catch, co2 is the number one greenhouse gas, which means that your room will heat up a lot after enrichment. co2 absorbs infrared heat light causing the molecules to vibrate, which creates warmer air that acts as a blanket.

how would you keep the ducting from getting caught up in the door when you open and close it?

the tap water where im from ranks in the top for most polluted- 700ppm out of the tap so i dilute it until ~100-200ppm. took out 2 bulbs of the T5 to drop temps a little and raised the light up. added slight nutrient, not even enough to raise the water 100ppm just in case of nutrient deficiency...

added half tap half distilled ~200ppm but still dont look any better, though its only been a day im just so impatient on what the hell can be going wrong. they are still on their first set of leaves and are looking a little yellow. does ph up or down eventually expire and go toxic? im...

it shouldnt have any nutes. i flushed it with distilled water before i put the seedlings in it to make sure

hey everyone, i need some help early in the game- popped 18 critical mass seeds 10 days ago and all 18 germed. i have one big problem though, they havent grown at all in seven days...and are looking worse by the day im running an 8 bulb T5 445W a few inches above the seedlings in canna coco, pH...

will do! only thing is that they aren't feminized but will definately clone it if its a female

I have never seen this in my life. One of the 16 critical mass seedlings has three cotyledon leaves. Has anyone seen this? Will it be any different during its life?

The room size is 5ft x 6ft with a 4x4 tray and 1000w reflector (I know this sounds crammed but there is room to walk around 3 sides of the tray.) The original design was to have a CO2 tank with regulator and a 8" vortex that would be used to draw air from out of the room to cool the reflector...

check out Onyx and MI5

I'm sure most of you have heard of organic growers using hydroton or sand in the bottom of their buckets for proper drainage and aeration but what about making multiple repeating layers of hydroton/soil/hydroton/soil/hydroton and so on without mixing the layers. I was thinking of doing this in...

critical mass /thread

THC and CBD both come from the same precursor CBG cannabigerol. I'm pretty sure that harvesting early leads to more THC but harvesting later when the trichromes are more amber leads to more CBD.

i'm from cali and i'm wondering where all the good skunk went as well. i remember i used to buy grams that were double baggied about 10 years ago and i had to keep them stashed outside or the entire house would reek...just off of 1g haha. bud is much drier today and most people are switching...

critical mass by mr. nice is available on attitude is the heaviest yielder by far. cm is a reworked version of big bud that was selectively bread for the best phenotypes. heres a cm specific forum http://www.mrnice.nl/forum/critical-mass/ dont believe tangrine dream just yet. its far too new to...

sorry to say but i have reason to believe that their results are not accurate. I have completed over 12 university chemistry courses and have a fair bit of knowledge on extraction, purification, and identification of unknown compounds. Believe me, any percentages of THC/CBD/CBN etc that are...

height wont be a problem, SLH does sound kill but im hesitant on the 10 week flower. what would yield more- SOG Lsd's or a couple big SLH's under a 1000w?
