DIF is the difference between night and day temps. the smaller the dif the less stretch. during veg a few degree positve dif will keep stretch to a minimun. a zero or negative dif, can cause damage, and should be monitored closely, don't mistake yellowing for a nute or ph issue, when changed...

u need stable constant levels. u cant just burp on them once in awhile

the only thing i want growing in my rez is roots. i just dont understand the concept of organic+hydro, its one or the other, not both

of course when the flowers get big be careful not to burn them (before they're dry :) )or let rh raise above 40-50% at all, especially moniter when the light first goes off for a rise in rh. im now staring a prenight vent to drop temps two hours befor light off and one hour after. then heating...

can u stop pullin air from the outside.. i dont even run my ventfan this time of year. i rarely even take the cover off of it. . u can close your vent altogether. there is no reason to vent with co2. thats the beauty of it. just vent if you need to lower heat or rh.

http://www.hrt.msu.edu/energy/Notebook/pdf/Sec4/Maximising_the_Savings_from_Temperature%20Integration_by_SR_Adams.pdf The effects of TI on plant quality, bulk and yield needs also to be considered. As growers who use DIF or DROP will know, low-day/high-night temperature regimes tend to produce...

so u add stuff to up the ec and than u add stuff so the plants wont absorb the shit and the salt builds up slower on your gear so u buy there poop one more time before u figure out u got SCAMMED. that just seems silly. my rez stays crystal clear like a spring deep in the woods, and my roots...

the article from cannabis culture doesnt really take into consider co2.. the main point is that the larger the DIF (further apart day temps are from night) the more stem u get. u can controll stem elongation this way. im going to try a temp of 80 durning the complete preflower cycle 24/24...

Im interested in increasing night temps to 80 along with a slight breeze. turf seems to grow right through the night when its windy out and warm. yeah im going to try 80night. 90day. slight breeze 24/24. water 68. does this sound crazy. im looking for info on this, i might even try 90 one hour...

i got alittle more strech than i wanted but not to bad, just a couple more inches than i wanted. i think im going to add a heater durning the dark period untill the weather warms up some. the room has no heat so when the lights are off it gets to cold. i havent been running a dehu because...

im using recipe for success in dwc. is anyone else and is sugardaddy and b-1 neccesary in dwc? my roots seem better without the two once there establisted.

i use technaflora's-------boost, bloom, sugar daddy, awesome blossom, b-1, magical, ph pro i sometimes skimp on the b-1 cause it seems to screw with my rez in dwc and even the sugar daddy seems to mess with the rez. i usally go light on both

i use technaflora but the b-1 seems to mess up my rez, i think mayb cause the b-1 has some organic stuff in it. i use sugar daddy but it confuses me. with hydroponic nutes aren't the nutes already broken down for the plant. farmboss do you follow the reciepe for success from technaflora?? anybody?
