I’ve had some problems with maintaining an acceptible temperature range for my plants. This being my first grow has been more of a learning experience than I expected. I live in a log cabin in the mountains. That means insulation is negligable. So, as a result, I lost my first 8 seedlings due to a …

I can help with mh. Cool tube works fantastic! I can olace my hand on it. It pulls air from outside tent thru it, exiting out of tent. In veg you could go 24/24 but not in flower. Hopefully by then temps will go up.

If you have a thermostat and can adjust the heat use the 600w mh and hps turn your thermostat down and your fan on high in a 4x4x6 grow tent i use a 440cfm 6in fan and my temp stay around 83 to 85 in the tent

Installing an exhaust system for the MH/HPS is key. [image] First Time Grower Mistakes, White Widow Auto, Indoor, Soil, 400W HPS+400WMH Grow Journals I grow in a shed so recycle heat it’s currently -5c outside and my ladies with no heat except lighting are a nice happy 75…

With no windows and only a sliding door in this bedroom, i’m thinking about having to move the tent 3x3x5 to another area with a window so I can adapt venting. I have the fan, thermo, and ducting but was hoping to find a way to keep the tent where it is. I don’t want this to be a “decor piece” in my…

The viparspectra 300w only pulls 128watts. So it’s good for about a 2.5 sq. Feet. It’ll probably be enough for veg in a tent, but you’ll need more light for flower.

Ive only started 2 plants in 2 gallon buckets, so my footprint is not large (white widow). Im going to have to move the tent to another room to run the 600w light when it goes to flowering.

You can veg with the Vipars and flower with the HPS as you stated. Normally ambient temps are higher in the daytime so run your lights at night and let the plants “sleep” during the day. A 300 watt aquarium heater ($10) set at 85F and droppd into a bucket of water in your tent will maintain temps …

The heater is a much better idea. I plugged a cfl in the tent to raise the daytime temps with the Vipar on. The water heater can handle light or dark.

I have the lights at 24” and just watered today after 2 days without. My moisture meter works and I use toothpicks to …

So, 16 days later. I repotted the smaller one in a smaller pot with Fox Farm and then treated the two the same. Nutes with every feeding about every other day. Still about 20” below the 300W LED that’s only 128w. Just got a $70 more expensive electric bill for last month. That’s for LED? What happen…
