Fan or Blower Related
Clamps work well, but they can occasionally slip off when you raise or lower your hoods. I strongly suggest using duct tape. The best I’ve found is the silver tape that stretches (it usually has black writing all over it). If you use clamps use duct tape as well to ensure long-term effectiveness.
I put an oscillating fan blowing on my plants & the plants dried up. It looks almost like a nutrient problem, what did I do wrong?
You need to adjust your watering schedule and keep a close eye on your plants. It’s great they are drying quickly because it shows a sign of plant health. You do need to be vigilant on your watering to be a good grower.
The “booster” blower fans are pretty weak. Their CFM rating quickly dwindles as the length of ducting increases. The most efficient and quietest fans are inline fans. You can attach an inline fan directly onto your hood, your filter, or even between sections of ducting (connecting them).
Though most fans can, some cannot. I recommend going to the manufacturer website or contacting the store you had purchased the fan from to find out.
Depends. If you have another fan bringing fresh air into the room with the correct CFM rate then you are fine. If you need your “grow light” fan to keep the air movement optimal, then I suggest running it all of the time. RULE OF THUMB FOR AIR MOVEMENT: If you do not know what CFM rating you need for the correct air exchange use this method: Multiply your room length by the width. Then, multiply by the height of the room. This is your air volume. Divide the air volume of the room by the CFM rating on your fan. You want a complete air exchange over under, every 5 minutes.
Yes, all fans need a cooling period at some point. It is NOT at all common, but I once had a fan catch on fire simply due to it running way too long (2 years straight). Lucky I was in the room when it happened. Therefore I recommend your fans having a 15-30 minute down time once a day to allow the components to cool off.
