Hey everyone my name is matt im from australia, Have only been growing for 5 months, fairly basic setup but continually lookin to improve upon it. My first crop was 5 plants using 5 600w, growing in coco fibre using dutchmaster gold grow and flower chemicals, Liquid light and penetrator sprayed on every third day (not sure how beneficial it was as havent grown without it). First crop went great got bout 5pound with a 4 week grow and 10week flower, second crop was a nightmare we just finished a summer hot spell of 2 weeks of over 42degrees celcius cooked my plants 3 weeks after i turned them but oh well will live to grow another crop. Quick question i was feeding them three feeds a day using about 25 litres a day for the first 5 weeks then slowly increased the amount weekly was wondering how much other people were feeding there plants, water is running to waste not recirculating. also gotta work on my heat problem, im using a carbon filter with centrifical fan and only a bathroom fan pumping air in. Any suggestions would be appreciated. Cheers Matt
