Tent sucking into it self

[HonestGR]

Fyi, you have a flap on the bottom you can open, it will let more air in!

Whats the voltage draw from the wall with the leds. Generally the minimum wattage i go for leds is 32 w per sq ft. My rule of thumb If the number is below 32 you will need another it will be on the light specs!

Like you i got blurples. However i got quantum boards on the way. If you choose to buy another light..dont buy blurples. Save ya the hassle and time like ive wasted. Ya ive grown some decent smoke. Got some ok yields. But im tired of waitinf 10-11 weeks for "ok" yields and density.

11 or 12 days old, brand new set up with a 450w viparspectra, going to see how these girls turn out, might need another 450w, always only going to do just 2

jus be careful...me currently findin out the hard way that, despite what i alwayz say, there is actually such a thing as too much light, lol who knew-? haha me also have jus 2 plantz, and me had a 1000w full white led goin, and thru methodical (and a bit maddening, lol) process of elimination re a certain leaf tip issue since almost the beginning, have now discovered that quite simply, for the smaller space i'm dealin with, it was just plain too much light...so me gonna go old school with me t5'z & cfl'z till me figger out sumthin else ppp

What size tent are you using @420Forever ? I'm on the 24"x48" tent and the lights specs say I think about 640 ppfd with a range of 2.5ftx2.5ft at I think 24". I say I think because the guide is downstairs and of course and I dont want to get it, lol. So I think I may be fine with 2 ladies with that light but with another light, I thought maybe it would give a little extra push.

Opened the bottom one, but still noticed the walls were tight so opened a top one a little and seems ok. They are only 11 days old so no smell yet, monitor once the good days come, lol.

Negative pressure is a good thing in a passive intake setup. I run a 3x3x6 with a 6” exhaust and the fan controller is set to max (440 cfm). I run one vent open at the bottom. You want the cool air (warm air rises) to enter from the bottom.

Do you have a temp controller for the exhaust fan?
Did you get a small 6” reciprocating fan?

You definitely want negative pressure. I use two bungee cords each of the four walls top to bottom. They help a little and that's all I need.
I normally open the low screen and or the lowest sock and have the cable sock open that is opposite and located up high.

Just have an intensity controller for the the exhaust and have it on mid range and an air vent opened on the bottom, and yeah I have a six inch fan blowing on the girls. I've attached a pic of my set up.

bottom providez cooler air ppp

Which will also create a huge humidity increase... be aware
