well, thanx for the quick reply happy
i was thinking to follow the cloning technique with the ending of this grow....the subject of crossings and see production sounds very interesting and challenging but i do not think i can do that yet....anyway, i am thinking that by the time my next grow finishes i will save up enough money to buy me one more hps unit ,600 watt this time,plus one more NFT board with tray 4x3ft.....exactly like the one i have now.....really i think i will be doing 2 seas of green in the end...one with crystal and one with papaya.....and yes....being honest i did a lot of reading on overgrow to learn more about these two strains....crystal is a cross of white widow&northern lights and papaya is a cross from afghani&KC-33...both strains are very promising and they both finish@63 days....hehehe i will feed them with nuts for 8 weeks with one week of flushing......... i'm so excited man, i am about to build and a box/room for the growing.......the dimensions will be around 7x7x7ft (planning to fill the entire space with NFT systems gradually)....i am building it with long metal bars like the ones used for selves/storage, they will be held together using screws.....for the walls i will be using white reflective material (i think it's called telon, not sure)....from one side it's white and from the other black.....also, the top of the box will be open at all times for optimal ventilation (as well with some passive air intakes at the bottom)....the smell will be exterminated by using a good ioniser/ozone generator....the air will be refreshed constantly with a window open and with common household fans.....did i forget anything?
