Ok my set up is a cupboard 208 (high)x 124 (wide) x 54 (deep)cm in it i am putting a NFT tank that is 101 x 48.5 x 20.5. my light is a 400watt grolux.

What i am hoping you chaps can help me with is the timer settings for the various appliances. I am going to put my light on 18-6 as its going in my bedroom and i need a period of silence so i can sleep! So is the pump on continuosly with the light or does it have to be intermittant (30 mins on, 30 mins off, etc. for example)?
What about my fan? (no idea of its power but it kicks out cold air nicely) and i have roughly 23 x 62 cm of vent in roof. Do u think the fan should be on all the time the light is or less? I want the temp about 20-25 C in there?

thank u for ur time

Good set-up...
1. nft runs all the time...(I use every method but, nft), I think that is what I read. You see, circulation of nutrient solution is what provide's Oxygen to your root system...without O, your plants suffocate.

2.run oscilating fan 24/7...exhaust fans intermittently...Only when the lights are "ON" to remove hot air, which in turn, lowers temps. NOTE: In extreme environments HOTHOT you would most likely benefit from continued cycles of exhaust...AC, if possible is a great grow TOOL
...MY thoughts here are; In regards to AC/co2 needs? Although it is a fact that the proper sterile grow environment, with optimum condition's ..nutes...big light/s...temp controls//for; res...canopy...room...and co2 enhancement, all the meter readers, Bells and Whistles to Boot...
I feel that if you can keep your environment cool all around the plants, have and let the biggest light you can deal with; whether it be space issues/or just what you can afford...provide the warmth, but not HOT Heat, you don't need co2. Because the cool environment doesn't allow all co2 to be burned from grow room.Imho
I welcome any question's or comments you have on this theory; I am no expert, just a well studied conneussieur of our common interests. Imho.lw

3. I try to keep my temps at 70F...It is OK, not optimum, but OK up 85F, and Bad above 90F...hermies, root rot, bugs...OH the bugs
You can't really get TOO Cold, but you don't want to freeze them.

Hope this helps.lw :smokin:
