    New grow room. No more tent.

    So I have recently decided to get rid of the tent. This being said I've decided to add a 600 watt hps ontop of my existing 2 1000 watt hps. Do you think I could cool all 3 hoods if I use 2 inlines, one on either side. I'm running 4 strains from greenpoint seeds. 6 of each. 6x punch bubble. 6x...

    Plant Health Check

    Hey guys, just wondering if any veterans could tell me how my first grow is looking? I've started to notice some discoloration between the veins of the biggest fan leaves and worried this may be early signs of a problem. I hope you can make it out in the images. The weird haircut is the result...

    What's the average yield per watt?

    So far the only side by side test I've seen was done by Migro. They claim the average yield of an HPS is 0.5 grams per watt and 1.0 grams per watt for a quantum board (Samsung LM301B). Do you agree with these numbers and where would you position a standard LED light?

    Average Yield Per Watt Infographic

    I'm helping a few people grow so I decided to create a series of infographics rather than overwhelm them with unnecessary technical details. This one is a comparison between HPS, standard LED lights and the new quantum boards (Samsung LM301B). Can anyone confirm or refute the numbers, please...

    Hey Guys, I'm pretty close to harvest so wondering both for now and future grows as there probably is not much I could do in the next week or so. I'm growing Green Crack CBD and they are maybe a week out even less from harvest. I know leaves tend to go first but two out of the 3 plants are...

    Smoking Magnetic Ballast

    Hello, today I bought a new HPS 600W grow light kit. The problem is with the magnetic ballast when I plugged the lamp it started smoking and I immediately unplugged it. Is it normal to smoke when first started?
