I got one of these… is it too close to the tops?

[Jim Haddar]

Firstly, this is the light I got way back in November 2021. It’s in a 4x4 grow tent with no exhaust fan or ventilation except that we unzip it every morning. Lights are on 13 hours a day for blooming and finishing. I will post a photo of the grow tent and light next.

The light is a Barrina BU 2000 that I copped off Amazon, obviously. Here’s a pic of the tent.

The tops of the plants are about 9 to 12 inches from the light. The reason I am concerned is that a couple of the plants are foxtailing. Actually it’s my wife who thinks maybe they are getting too much light or heat. I think it might be a genetic trait because the plants are from the same batch of bastard hybrids from a previous grow, known mother/unknown father. This is one of the foxtailing plants.

The tent does get a little warm every morning before someone wakes up and opens it, but I doubt it gets much above 90 F.

Dang any reason for the no exhaust fan or ventilation?

Closer than 12 inches and above 85 degrees may be contributing to it............. and no ventilation?

Try to stay at least a foot away with that light. If you have it on straps loose them and just put it on the bar. Leave your arm in the light for 2 minutes. You can tell what's comfortable

Not being a D but i can barely see any bud too foxtail? Maybe the pic

Usually new led's are cranked up to 100% but they seem to function better at about 80%
Dim it down and see

I been running mine at 100%................

You might want to measure temperature rather than guess.

Zero air movement is gonna come back to haunt you

All circumstances are different
He is battling heat it seems

 

[Jim Haddar]

Thanks for feedback. I am raising all my lights and getting a couple fans.

How about getting 1 fan atleast and a inline fan and scrub the air with a filter or dump it outside you have to introduce new air for the plant's to take in new c02 what you put in your setup is what you will get

…..getting a couple fans.

Getting a couple fans for circulation inside the tent is a wise thing to do. Another wise thing to do would be to invest in an exhaust fan.

Unless that’s included in your “fans” statement. Keep the air moving. Stagnant air leads to no good. Not being an asshole, being serious. Some things you can skimp on, some things shouldn’t be skimped on

I will try to get an exhaust fan but anything else is probably outside my budgetary capacity for the time being. The plants have done okay so far but the latest crop includes some genetics that I’m not familiar with.

I don’t know your budget, but maybe start here:

The Best Deals Thread. Post Best Deals And Lowest Prices Links

I thought it would be cool to have a running thread dedicated to the best links to buy from that has the lowest prices ansd best deals. It would save alot of time,trouble and ppl posting asking.. I have a few links to get it started.. I cant speak on behalf of these items as the only ones I...

www.rollitup.org

Post in the thread for a coupon on an exhaust. The guys that are good with that stuff might be able to help you out. Sometimes some friggin good deals can be had in that thread.

Edit to add:

You don’t need to spend big bucks on an exhaust. Just something decent enough to pull in fresh air and exhaust out air. I personally have a few AC Infinity 4” and 6” fans and love them. May be out of your budget right now, but something by to consider in the future.

I'd think even a cheap ass 20.00 inline would cause a noticeable difference.

Exactly. Something is better than nothing.

I’d go with an inline fan straight into a duct port and one circulation fan in the tent over nothing.

that light will cover about a 2X3 area, you're going to need another one if you want to get good results in a 4X4 tent. anything outside that 2X3 area is going to be getting pretty weak coverage.
a rule of thumb is 30 watts of leds per sq. foot during flower. your light is 200 watts, that's slightly over 6 sq. feet of coverage, and you have 16 sq. feet. even with two of those, you'll be getting the bare minimum.
