Hey all. I have recently just built a veg room in my loft, adjoining onto my main room. Dimensions: 1.7m long, 0.85m deep, 1.2m tall. Solid room made of beams and loft paneling, insulated with 50mm poly boards and then fully mylared. I Will be putting a 4 inch output fan in to vent out and leave door ajar to bring air in with an small desk fan to oscillate around, this will be done next week. Ive just fitted a 300w CFL with reflector in as I just had it doing nothing and as I speak running some tests with 3 hemp seeds just as a practice, As I am a newb to doing. I will be aiming to crack open my 5 Kalashnikovas (GHS) soon, and a choice of 1 or 2 others. I have a red diesel and Honeysuckle which keep taking my fancy. My temp is averaging at 24 degree, highest this week so far 25.7 and lowest is 23.1, light on 24.7. My light is as high as will go, around 1m high, with the 3 hemps on the floor. I soaked seeds for 30 min while I saturated coco in small pots with some root stim and let that just drain and soak in in the meantime. then just stuck the seeds 1cm into each pot. Took 3 days for them to rise which was yesterday and since that they have grown 4 inches. Now I know these are hemp seeds and they might grow differently I dont know that much, but 4 inch seems a lot to me. Could the stretch be having the CFL light up at 1m? All 3 pots already have a big root coming out of the bottom and im just giving them small amounts of Growers ark rootstim and first feed, little and otfen to keep moist. Im confident this environment is good enough to crack my Kalashnikovas soon. Is yet to be vented but I am installing a small 4 inch fan next week. But is the CFL good enough at that height as Im a bit surprised at the stretch of the testers im running. My actual area is only one half of the room, as it is long and narrow. Im aiming to be able to house 8 to 9 young plants when im confident over time in there in a 60x60cm deep garland tray. Would I be better switching to a cooler bulb in the hotter months as I feel all that CFL is a warm old thing. And if so, what are the best bulbs for that space? A lot of questions I know, but I love this site and trust you all to be as helpful as we always are. Thanks lots.!
