Long length grow cycles + slow seed starts

[Richs]

I have 2 grow tents (4x4 & 2x2). The smaller tent has 2 600 W LED lights; the larger tent has 2 1200 W LED lights. Both tents are maintained @ 72* F with humidity 35-40%. Compared to the grow timing I've read about, my plants take at least 1/3 more time to mature! Any suggestions?

Wow 1200 Watts in a 2x2? What brand lights?

What kind of lights are they? My plants always take bit longer than advertised but not but a week or two

Small tent has 2 600 W, but the tent is 2x4, about 5' tall. The 4x4 has 2 1200 W. I try to keep lights 20" from the plants, but when I can't, I turn the lights to 1/2 power. I've had fans to circulate air in the tents, but have just installed exhaust fans to get some fresh air inside. During the summer I have left the tents open.

The last crop took 9 months, seed to harvest.

your lights aren't 600W and 1200W but much less most prolly some shadowy brand that give misleading model name to their lights, there's many of that kind ...

The lights in the small tent are Marshydro, whereas the larger tent has Phlyzon brand.

improper watering pratice could be the reasons for slow growth, there's some others.

also give your lights models name it will make things easier your confusing the actual watt they use with something else.

 

[HerbalEdu]

in a 2x4 you will usually have 200w to 450W

in a 4x4 500w to 1000W and that's with co2

there's no 600w model where you can have 2 in a 2x4 and no 1200w models where you can have two in a 4x4

your mars hydro light might be ts600 wich is 100W can't find the phlyzon models you use ...
