I never used hygrozyme or anything that protects them from heat. I have noticed that after 10 hours of light water temp rises to 24,4 C which is 76F. It wasnt exceeding that temp though. I am trying to chill the water with frozen water bottle but I can only fit a 1l coke bottle there because of...

thanks for sharing your knowledge Morris. I never thought of water evaporation as a reason of my pH changes but it seems perfectly reaonable if you think it over ;-) I am just going to check my pH now. I don't have a ppm meter yet but I might be buying one next week - seems like it's a tool that...

wow, thanks a lot! I'll get rid of the humidifier today ;-) The only thing that concerns me is that I am using a very complex mix of nutes for my system. it consists of: 1. GHE Bio Roots - organic composition for root growth 2. GHE Bio Bloom - organic, extending growth in veg state 3. GHE Bio...

Hi Agent88, Thank you for reading my thread and for those great professional advices. I have never heard of the nutririons you recommended but I did buy some GHE organic compositions for aeroponics. They are: BIO ROOTS, BIO BLOOM, and BIO PROTECT (for spraying on leaves). I think that...

the air is being circulated all the time. there is an intake fan that provides some fresh air from outside. the fan is pointed towards the plants and humidifier.

tips of leaves are curling up. I have taken another picture of the same plant - another leaf - you can see it much better there. Another plant in the next picture - curling leaves.

Hi, I have made a dramatic change to my setup today: 1. added steam air humidifier - humidity in the tent increased from 26% to 36% in 16 hours 2. changed light - i found out to have a bulb that is 95% flowering and 5% growth. I have changed to MH GIB GROWTH lamp today. 3. trimmed my plants...

I was happy to find my plants alive after being 3 days away from home. Looks like my heat/pH/nutes problem didnt do much harm... What have I commited this week? 1. Balanced pH (hopefully) It was said my pH is rising all the time because I have not presoaked my rockwool with low pH water in...

thanks for your help guys. I have just came back home after being away for a while. This is what i have found out after coming back home. I am still using 1/4 dose of TOTAL GRO and BIO ROOTS. Should I change the water in the res for a clear distilled for a day? I am planning to change water soon...

Guys, I have just read the sticky thread again and I am starting to suspect it looks like Mg defficiency. What would you said? Please take a look at the curling leaves and brown burnt spots - is it Mg deff or nute burn or those two together? I am away from my plants now for 4 days and I am...

Another busy week... It has started with a dramatic pH fluctuation problem that I couldn't resolve. It led to few improvements of my setup and another few thoughts for the near future. Ok, so I was having a pH changes of 1 up in 12 hours - I was doing my best to balance it, checking on it and...

Ok, So I have just came to see them and I am still rcovering from this terrible shock I experienced. Only few minutes later when my hands stopped shaking and I was able to get a camera I have taken this ones... Please please take a look and continue reading! My water was 6 days old today so I...

my rez can hold 45 litres (12 galons) and is filled with 25l (6,5 galons) of demineralised water.

should take the baskets out and soak it with pH water now? I am checking the pH every 12 hours and balancing when needed but I am planning to leave for 4 days soon - I really need to sort this pH thing soon... I am planning to change water this Tuesday or Wedensday - it is starting to smell and...

Thank you for reading and for helping me out ;-) I have germinated the seeds in this rockwool - it was completely wet by that time. But I have never soaked it fully with pHed water - is there anythig that could be done about it at present?

I don't have any ppm meter. I have added half of the dose of GHE TOTAL GRO and GHE BIO ROOTS that should be added for vegetation period

Hi Guys, This is my very first grow and I am very concerned aboyt my plants. I am growing in aeroponics system with rokwool as a medium. I started adding nutes last week (now I think it was little too early). My system is having giantic problems with pH fluctuation (1 pH up in 12 hours!)...

Hi, I've got a pH problem that I cannot solve - is there anybody here willing to help? I was using 2 days old tap water in the beginning, but my pH once balanced would grow by 1 in half a day. I had decided to change to demineralised water, but when I was filling my res for the first time I...

same problem here with an aero setup ;-( I am using an airstone and I suspect it to give me part of the problems. I have also been using tap water but now I am planning to change to a distilled water - I'll let you know if it helped.

pH meter that I ordered last Friday has been delivered today. I was glad to find out it also has a built in digital thermometer. I couldnt wait to use it so I have calibrated it and tested my water. I have found out to have 2 problems: 1. water temp was too high (27 C) 2. pH has changed to...
