  1. Hello all and thanks for to admin for approving me. Excited to join the community after spending many hours reading up on several topics. I'm looking to start my first (small and low budget) grow and although as stated I have done quite a bit of research I'm getting some mixed information so would appreciate if anybody could point me in the right direction on a few things. I intend to grow only two plants to begin with, most likely some autoflower NL or Jack Herrer as I've read that these are short, easy to grow and less difficult to keep on top of smell wise than say Blue Cheese or White Widow. TENT Firstly, I have a tent 80cm x 80cm x 160cm that cost me next to nothing from Amazon. It has a couple of pinhole (and I mean a hairs breadth) that are sometimes visible through the zip - will this have any negative effect? This may sound silly, but I've stood inside it zipped up and I can't see jack, so I'm guessing it's nothing to worry about? LIGHTING I impulsively bought 2 £30 no-brand "216w Dual Spectrum LED UFO Grow lights" to go with it. I saw on Youtube that the actual draw of these lights is 65w but they apparently emit the same amount of light as a 216w HPS. The description is as follows - LIGHT SOURCE: 72 pieces of 3W LEDs, high lumens of 21,600LM, high power Par Value ensured, it is environmentally friendly. BLUE LIGHT: contributing to plant photosynthesis, promoting growth, protein synthesis and fruit development. RED LIGHT: promoting rhizome growth, blossoming and bearing fruit, extending flowering phase and increasing output. FULL SPECTRUM: wavelength of 410nm-730nm, white and warm white, providing natural light for various plants in different growth period. GREAT HEAT DISSIPATION: built in a cooling fan ensures great heat dissipation and long lifespan of 50,000 hours. After further research on these cheap no name LEDs I have come to the conclusion that this description is most likely bullshit. I stuck a couple of Komodo Dragon chilli seedlings in the tent a fortnight ago, to give the lights a test run and also to see if I could control temperature and humidity with the basic equipment I have. The fan in one of them is already bust and I'm going to return it. I don't hold much faith for the lifespan of the other one either and still have 20 days to return them both for a refund or replacement. Would I be best to get a refund, steer clear of these shitters and go with a CFL, perhaps a 300w as this would give me approx 50w per square foot? VENTILATION This is what I'm really struggling with . The tent is in a bedroom, which I spend most of my time (I live alone in a large upstairs flat and its cheaper for me to heat one room in the winter) and from what I've read, for me to effectively run exhausts and intakes outside would mean I'd need ridiculous lengths of ducting and stupidly high powered fans all over my place or start knocking holes in ceilings (which is a no). Is it okay to run intake and exhaust into a small tent from within one room? My tent is 35 cubic feet. I have a small duct booster that I intended to use for intake that is rated at 103/cfm. It's nice and quiet, low powered and didn't cost much. I'm looking to purchase an extractor and have found this formula on google to work out my needs - "To calculate multiply length x width x height of growing area e.g. A room that is 8' x 8' x 8' will have a volume of 512 cubic feet. Your extraction fan should be able to adequately exchange the air in an indoor garden once every three minutes. Therefore, 512 cubic feet / 3 minutes = 171 CFM." By this theory I'd only need a fan with a rating of 11cfm which can't be right can it? After using another calculator on a Hydroponics store website they advised me that I would need a 200cfm fan with a 300mm carbon filter. Does this sound more realistic? Also I've read that the restrictive effect of the filter will deduct 20% from the CFM rating of the fan which would only give me 160cfm, which I'm guessing won't be enough with my 103cfm intake to maintain negative pressure. This shit is baffling me. Would I be better to buy a 200cfm extractor and filter, open up all the vents for a passive intake? Would that mean I'd have to run the extractor fan non stop night and day, or would I have to do that anyway? I'm guessing so if I need to maintain negative pressure. Carbon filters - After much reading I pretty much get the jist that Phresh, Can etc are the dogs bollocks and the cheap £20ers are not worth a wank, even that the Rhino Pro's arent 100% in odor control. I've learned from my experience with the lights that there is a lot of shit out there and skimping can be a false economy but my budget is seriously tight. Can anybody tell me from experience if some of the cheaper but branded filters like OX, RAM, Rhino hobby, Swiftair etc actually do the job (even for 6 months) of removing the odor. Like I've said I'm not talking about a warehouse full of prize winning Cheese here, just two plants. I also know there is the DIY option, I'm pretty handy but I would be pretty pissed off if I spent the time and effort making something that is no better than a £30 jobby I could have ordered from the bay. I've found a site selling Rhino Pro's starting at £35 so I'm edging towards this, but the skimper in me says to try a cheap nasty £45 full kit with a fan from ebay. After all they've sold over 1500 with mostly positive feedback. Thanks in advance to anybody that reads this and can give me any tips, hope I've not put you to sleep. BN
  2. Good Evening everyone Lurked for ages here and got the growing bug Using autopots for the first time with this grow of four plants (in the past it's been compost and watering by hand) They were thriving in week two of flower, I filled the res and went away with work for seven days, hoping they'd be OK. I've got back tonight and they're devastated, looking pretty grim if I'm honest They've totally emptied the res (I'm blaming the heatwave) and I wondered if anyone had suggestions? The main stems seem to be OK, but a lot of the leaves and secondary stems appear dead n crispy. I've refilled the reservoir tonight with half strength nutes and removed most of the obviously dead bits. I'm thinking to leave them a couple of days and see what happens (on 12/12 or 18/6 I don't know) Would it be possible (or sensible) to re-veg these plants? Or take cuts and re-veg these? Or, should I just cut my losses and start from fresh again? (I usually grow from seed due to space restrictions) Any advice would be most gratefully received, honest.
