Hi, i'm hoping i can get some guidance, Just started my first ever grow, still in seedling stage, No nodes yet. It's 2 plants, one sativa and one indica, which i realized in hindsight is stupid since They Have different flowering times😅 Currently my only light is coming from a full spectrum led that pulls 240w off the wall, but was supposed to be equal to 1200watt hid, i very much doubt that so i Have ordered an additional light, a hid 400watt, and both mh and hps bulbs. Both seedlings are in dwc at pH 5,3 with calmag water. No additionnal nutrients at this point. They went in the dwc this past weekend. The tent is 3,3x3,3x6,6 ft. Do you think i need more light? The nutrients i'll be using are advanced nutrients pH perfect sensi. In addition i Have bought some extra nutrients because the nutrients calculator on their webpage suggested it, so should i Follow the calculator, or should i Just addjust the nutrients to fitt a certain EC? I read that in the start of vegetative phase i should start at EC 650? And would love any tips and input as i am completely New to it😅 sorry for spelling errors and bad grammar, not my first language☺️ love from norway☺️
 
Someone with DWC knowledge will help. That mh & hps runs hot in a little tent won't it? I would purchase a quantum board LED so the tent won't get so hot. I am a soil person so no help from me with DWC. Seems to me those units take alot of head space.
 
I Have exhaust fan from the top of the tent that is controlled by thermal sensor, so i was thinking it might be enough to Just Open the window in the room the tent is in, since temperature drops heavily in norway in september, i Have No idea if its enough to cool the hps though😅 as it is now its keeping around 80f. Gonna look into qb led, thanks for the tip and reply☺️
 
400W HPS/MH shouldn't put off too much heat. I had one running (at 375W) for a little while in a 4x4x7' tent and just have a 4" exhaust (190 CFM I think) running. Works fine for me with my window open and a window fan in it. If you go that way, try to get a vented reflector to keep the heat down in your tent.
 
It Will be hps in the beginning since i already ordered it😅 so going to try it out and see what temp i get up to. My exhaust is 5", also a small circulation fan inside the tent. Hoping i can run both lamps simultaniously, but what would be the max temp i can safely run on? Thanks for the reply☺️
 
For DWC you're going to want your temperature about 80 or under or you're going to have root issues. A lot of people run a chiller to keep water temperatures lower but you can do it without. Damn things are expensive anyway. My tent stays about 80-82F with the lights on usually and my hydro is fine so far. I had to get a portable A/C to keep temps down though because I have 3 lights in there and it gets hot without it.
