25+ days of flower and no signs of bud. 4th grow in this room. 4000cfm on 1000 watt in an 12x 12 room, sectioned off. i run really hot(summer) but it's like a hurricane in their. pure blend, cal-mag, pro-silacate and liquid karma in foxfarm soi. 65-75 degrees lights out....88 to 110 lights on. It's so hot outside. I have seen with my own eyes plants(cannabis) growin outside in 112(day) to 80 (night) and do fine, 4000cfm is an incredible amount for that 1 light. ( one 2000 cooling light and pulling through scrubber exauhsting outside , 1 2000 blowing on light and girls. I was also told several times by people repected on this site that high temps are o.k. with proper ventilation.
So why won't my girls flower? P.s timers not broke, no light leaks, very low humidity and run about 5.9 to 6.3 p.h. varies. 3rd gen. clones thats it, i think.

Please don't respond unless you know. I know it is "to hot" circumstances out of our control, but how to combat it. A/C is not an option, to much power consumption( would need re-wire) and to dry here(8-12%) humidity. re-wiring, buying an a/c and humidifier just isn't acceptable. I have about a $1100 in already, and can put out no more with out more return first.

This is for meds, not just to party( no offence intended) myself and 2 others are in need of this medicine. My gulit is getting pretty heavy, i was supposed to be "ready" the end of this month. My friend is terminal, so i have to turn it around!!Any correct advice is desperatley needed. Thank you in advance!

Maybe its sabotage!

What strain is it? It might be the genetics.

are these all feminized strains???

Hello if youve grown these strains before and this has not happend we must narrow down what the problem could be..There has to be some type of light getting in some were..How bout from a fan or power supply switch thats glowing some?..What about around your exhuast vents light seeping in there.?.To much nitrogen in your bloom solution? Heat will not delay flowering it will effect bud growth some what..If none of these are factors it may well be genetic but with 2 diffrent strains im going with room condition..
Hope you can get this worked out for your friend and yourself..
take care

What is the timed light cycle your lights are on now? Which PBP formula are you using? Fruit and flower flormula, Soil formula or some pbp veg formula added in? I know these may sound like silly questions but we need to know what your mix is, etc to help. Hope we can straighten,or identify the problem for you. Light leaks will mess up bloom, is the room sealed against light leaks?

Light contamination would have to be significant to delay flowering in an entire room, little glows and such do nothing to the photoperiod.

Nitrogen in the first few weeks of flwoer is necessary for stretch growth and shouldn't effect the onset of initial flower production.

Jexter, you're not even seeing pistil clusters at the tops of your colas?

Mazar flowers for 60 days or so, so your just a 1/3 through. Maybe patience is the answer?

outside is not the same as inside. you may have seen them work outside but have you ever seen them grow a cycle inside like that??? probably not with any kind of decent result.

if you are going to run those kind of temps you need C02, or you arent gonna get much any results, and even then that's still too hot.... if you had results they won't be optimal ones. and that aint gonna happen with the type of venting system you're trying to use there.

secondly how is that ventilation proper? 4000 cfm for 1 12x12 and 1000 watts! ????? jesus man! you are probably using almost as much power running those 2 fans as you are that 1 lamp.... how big are your vent ducts? if your ducting is only 4 inches you are only pulling the air out at ~200cfm no matter how big your fans are, 6 inches will do 400 some cfm i believe it is.... either way with fans like that you should be running 8 to 12inch ducting i'd figure.

the filter through light and outside is ok, but where is your fresh air comming from? If you're gonna run 2 fans IMO you should do 1 fan sitting on top of the carbon filter and sucking the clean air out to the outside or a neutral room. and 1 fan for the light in a seperate loop , so that it's pulling air from a neutral source (outside or adjacent room) over the lamp and right back into either the same or a different neutral source .... no filter or anything to slow down the air.

after setting up the cooling as such, I would probably add another small 180-265cfm fan pulling air into the grow from a neutral source (outside or adjacent room)


just rambling off some ideas for ya...

like THCaESar said, if you gonna run that hot, you need co2
