I'm going to be using compact fluorescent lights for the entire thing. Yes.. I know.. I know... I SHOULD get a HPS light so i can penetrate the bud and blah. It's gonna be light an airy yehh. okay, also, now don't shoot me... I'm not gonna be really having any ventilation either.. The most I could do is put a fan inside of it and leave afew openings to let air pass through. Thing is I have never grown before (and only ever smoked once) and I am on an extremely tight budget. You all know the higher I will get the more I will want better buds and the more I'll want to purchase a better setup in the future. So what I need from you guys is help on getting this set up. I a…

hey guys and girls, another question - i've asked if it is at all possible to decrease the period it takes for any particular strain to flower. i was advised that it was strain dependent, however i've heard otherwise. i grow in 10% perlite and 90%coco - the strain i'm growing is white widow by dutch passion and it recommends an 8 week flowering time. mine are in theie 9th week and look like they have another week left. i was wondering if any of these factors below can increase flowering speed: The method of growing - eg. if i moved from coco to clay balls 100% hydro setup (because they are getting more frequent watering (and more oxygen) instead of once every 24 hrs) …

Hi people ... newbie here (I have had some experience in hydro a while ago) I have read an awful lot of topics about aeroponics here and on other sites. (it's taken me 2 weeks to read up ) I still have a couple of questions so far, and maybe more later on 1. Are the sprayers run on 30 sec on and 3 minutes off, or 1 minute on and 5 minutes off.. I have seen both .. is there a difference? 2. Once the plant is switched to 12/12 for flowering, do you leave the sprayer cycle on the same as above, or turn them off for the dark period .. or something else ?? 3. Do you need an airstone in the reservoir to aerate the nutrient solution or with this system is it unn…

Hey guys, I have successfully established my 3 pot, 6 plant top feed hydro set up. Originally running just a 400w digital, I have now added a 600w and in a larger room. (Had space problems originally) I have a 50L nute tank, and have been using all the Canna products. Zyme/Rhizo/PK 13-14/Boost Including AB Flores and Vega. Im also using Budlink (Liquid silica), and some Bud Blood. The first time I used Boost, I could not tell if it worked properly, because my girls ran out of room and could not flower properly. However, The smell and flavor was unwatched to anything I have had before. At $195 a bottle I'm at the stage where I can add it again, But before I make su…

I've been foliar feeding to counter what I think is nutrient imbalance in my soil, or maybe bad nutrient movement due to temps/PH. I guess some of the lack of discussion is because of the high percentage of people using 'perfect' nute solution on inherently sterile media. Anyway, I was reading this general doco on FF and thought it may interest some, http://foliarfert.com/pages/introduction.htm. Would one reason for avoiding this be fear of 'contamination' of foliage?

Hey guys, i was looking this up and was wondering if there are any noticeable differences between indica and sativa strains when it comes to early growth? im growing bagseed and the plants are a month old, grown from seeds. im wanting to know if they are either indica or sativa or hybrid, etc, but im not sure what to look for. Are there characteristics showing during early growth that can help us tell them apart? p.s. i know the differences between them when theyre older, taller, thinner, branchier plants and leaves for sativa, etc.

Hi guy's, What are your thoughts and views on people putting other drugs such as amphetamines/herion etc into their grows. Me personally think it is a crock of shit and here's why (taken from another post....saves me retyping): Why would you inject amphetamines into a growing plant? Wouldn't the injection cause necrosis of the cells at the injection site due to its' unnatural composition' (PH etc)? Please explain how the plant would metabolise the amphetamine and convert the active ingredients into the plant structure? Explain also how amphetamines would not destroy root zone microbiological (and other cellular divisions) activity which is crucial for plant li…

After only using perlite, I have recently acquired some bags of Hydroton, Coco & peat but have no experience with these mediums, what is a good mix? I was also looking at using DIATOMITE in a mix due to the silica it will provide to the root mass. So let me know what to mix for my next grow........ Thanks in advance, Canaman

Hi All, I've just started trying EXPLODE which was given to me as a sample (trial) product on the market. I am really interested in some feedback from those who have tried this already. I have seen some differences in the plants from the start of bloom, and was wondering if anyone else is seeing any change with their plants too. Thanks for the replies.

http://maximumyield.com/article_sh_db.php?...featureVar=true Differences Between Organic and Inorganic Plant Growing Systems by Dr. Carole Ann Rollins and Dr. Elaine Ingham 2009-07-01 There are some significant differences between an organic or biological system and the inorganic approach. Although the goal in both systems is the same - to grow healthy plants in the most cost effective way, the philosophical underpinnings of the two systems are very different. First, the biological system requires adequate microbial food in the soil, with replenishment by plant exudates in their myriad forms. Food comes in the form of nutrients such as sugar (bacterial food), proteins…

OK , I'm stepping up with the times and going to do a DWC grow . What water Temp ? What EC , PPM etc ? Half strength or full? What PH ? I'll be using what I have here , net pots , perlite ( I know clay balls are better ) . Dutch Fest nutes . Should the pots touch the water when I first start as the clones dont have roots hanging out the bottom of the pots yet ? I am excited at this , as I hear the growth rate is quick/quicker than what I am doing now , just Perlite pots watered by hand every couple of days sitting in kitty litter trays . Are the yields bigger/better ? Any help/advice much appreciated Cheers CG
