Lighting and my first grow tent

i have read everything I can find on line regarding sufficient lux for cannabis growth. I have. 4x4 tent with 9 plants in it and they got so bushy and grew to different heights that my single 800w LED wasn't enough so I got a 1000w to add plus I have 2 count 100w CFL clamp lights and a 4' T12. When I measure lux I am understanding I need about 35k lux at top of canopy but the LED don't have good coverage at lower heights. I am going to pull the 4' t12 set and add another 300w led to cover tallest plant and keep the 800w & 1000w led's lower to help with shorter plants. I am at end of first week of 12/12 and have 4 autos and 5 fems in DWC. Any thoughts as to best bud production versus LUX readings?

t 12 . not worth the space . the 100w cfl not worth it to much heat. both need to be taken out now worth anything . what brand led ??

Bossled LED's with IR and UV. The CFL are to help with corners. The T12 definitely adds heat but I get good veg growth out of it. When I move my 300w led full spectrum from clone tent to 4x4 I will pull t12. I just bought a 4bulb t5 setup for clone tent. I hope to have it by end of week.

I have never grown and my Afgan Nightqueen auto flowers started out really week... I almost pulled them...now they are my tallest plant and are 2x the size of the Amnesia Haze and OG I have. I don't want to screw this up and waste 16 weeks if I don't get buds right.

not a very good brand . what ever watts the led is divide it by 4 . suggest a hps 1000 watt air cooled hood major yields. or invest in a better quality led . or use a lot of those leds lights . those t5 will be a lot better then those led lights in flower i bet ,,you can buy a 2700 spectrum . not picking on you or the led lights . i have a cheap meizhi 1200 watts i do a 4/4 area with different size plants and they love it .

You will find that when growing normal plants that are not having any crazy shit done to them will pull the same if not more with less plants. 5 arranged like they do on dice is optimal for that space.

I have a light meter and 800w at 15" from canopy I get 35,000 lux. Mfg says it's rated for 4x4 tent but I added a 1000w to cover the other 2x4 area of tent...9 plants was way to many....luckily auto flowers will be done before normal feminized ones. I hear robust growth is needed at 15k lux min and up to 50k LUX.
