5700K will be fine for veg.

This might sound crazy but... I was running mine at 90*F (32*C) for the last week. Responded well. No signs of heat stress. Growth rates seemed to improve. I'm pumping it up to 93*F today. The lights turn on in 4 hours... I'll be able to see how she responds to the increased temps a little...

I'm currently using 2x Hortilux FS+UV 24" T5 as supplemental lighting... 48W. My grow lights are 8x Samsung F-Series 3000K and 6x Samsung F-Series at 3500K... 160W Veg, 280W Flower. I also supplement with around 8W of 730nm LED. 4x2 grow area. At first the lights were just a few inches from...

Dude... I've grown for some time. My family had a 5 acre outdoor farm for 5 years and grew medium scale indoors for about a decade. Ive grown on and off for about 15 years. I've grown hydro, soil, organic, indoors, out, co2, with hid, fluorescent and led. I've been around the block once or twice...

I'm definitely not a big grower... If you follow the VPD charts, they are going off of leaf surface temperature (LST). You don't measure the air at all. Depending on what your light source is, the lst can change. HID lighting will have a higher LST than an LED with the same ambient...

Most LEDs normally don't put out much IR (unless they are designed to do so). IR heats the leaves beyond ambient air temperatures. It's the temperature of the leaves that regulate transpiration, not the air temperature. To get the leaf temperature of plants growing under LED closer to plants...

You need something to absorb the vibration before it gets to your tent. Try hanging the fan with bungees. ^ beat me.

Ummm… circulating the air.

Lower your RH (especially at lights out)... Add some uv...

Algae is not USUALLY a problem. A bit of algae on top of hydroton or rockwool for example is no big deal. A little in the rez/can is no big deal... as long as it's not going to clog anything, is not so much that it takes a significant amount of nutes from your plants, and as long as it's only...

You can always try and re-veg them to monstercrop.

https://www.amazon.com/gp/product/B00JWU5OIW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 This is what I use. It will turn back on after the power is out... but it takes 3 minutes to do so. Avoid the thermo-electric (peltier) dehumidifiers... they are very inefficient and only good for the...

You can add side lighting. LEDs will be perfect.

As long as cool air comes in through the bottom and warm air goes out the top and it doesn't get hotter than the low 80s (about 28c), you're probably good. I've been told you want the air exchange to happen at least once every 5 minutes, I personally like mine to happen once a minute or more...

They look good... maybe a bit leggy... but healthy overall. Yeah, you can take clones in flowering... it's called monster cropping. https://www.rollitup.org/t/monster-cropping-increasing-yield.346874/

Does the exhaust push out humid air? I was always under the impression that air conditioners rely on 2 heat exchangers. On the hot side, a compressor compresses Freon gas, which makes it hot, and is pushed into coils. Then a fan blows across the hot coils, removing most of the heat... making...

I don't think the pruning is the main advantage of the oxygen pot... I think oxygen delivery to the roots is their selling point... and I really don't see that helping too much with a bucket right next to it (like you mentioned). I made an improved (IMO) version one of these systems in the...
