I moved my spider farmer light from 18in to 20in. But I maintain heat in that room very well within 3 degrees. There has yet to be a lapse in my daily lows and highs. But I was thinking the same thing about the lights giving off too much heat to the tops. So I'm trying that. Thanks.
Ok thanks guys. I'll take more caution around the plants. Will this effect on the yield? Or future growth? F-series you say they will throw out new ones, you mean new hairs?
Well, I cloned then from my last cycle. So I'm sure female.
I have not sprayed anything and as for rubbing against them, I doubt it I dont play with the buds and because its scrogged there is no traffic.
I'm a novice grower myself. What's the humidity in your grow room? It could be mold spores.
Also possibly spidermites.
But again I'm a novice, I would check with someone else before doing anything drastic.
Good luck!
It's good for circulating air below the canopy. Also helps cool, not like an a/c but better than a normal fan.
I bought it for my daughters room but we now have central air. So I'm "aloud" to use it now.
