Hey! I’m reading that you should have at least 7500 lumens per sq ft to really take advantage of CO2 enrichment. In a 4x4 area, a 1000w HPS has sufficient lumens (9375 lumens per sq ft) but not a 630w CMH which has less than half as many lumens (4125 lumens per sq ft) even though both lights are...

Any tips on syringe storage/maintenance would be greatly appreciated, do you rinse with water between every product you use? Do you rinse it out after every time you use it? Where do you store it? Thanks!

I'm growing in soil but have a couple water reservoirs that I'd like to keep oxygenated and mix nutrients with, I've been told that adding air to the water has a lot of benefits like removing chlorine and other unwanted solvents and impurities.

I'm growing a Green Crack strain, it was advertised as having a maximum yield of 600 grams, is it necessary to incorporate training techniques like "topping" to reach that kind of yield? Or can you reach that yield without using any training techniques and just leaving the plant with one big...

if a filter was there it would block the hole so the smell couldnt escape from the intake, ill try setting it up outside of the tent thank you

i live in alberta its super dry, i have a grow tent with a humidifier inside and fans for intake and outtake, when the fans are on 24/7 it doesn't even get up to 60% humid so i have to turn the fans off every hour for half an hour, (have a timer set like this (1 hour on, half hour off, one hour...
