Switching to bloom nutes and photoperiod changes?
When should I start giving bloom nutrients and stopping the veg nutrients? Also can I switch my light cycle to 24hrs to increase the temps and maximise my yield? Or will this mess with the plants?

IR cameras and ligth
Are IR cameras dangerous for the night cycle? I have my plants on streaming and I'm thinking of placing an infrared camera and IR LED I'm worried that the IR light can stress the plants and interrupt the night cycle. Wave you experience this with security cameras?

Grow Light Popped Its Clogs.
Hey Guys😬 So my grow light has popped its clogs, but I am currently unemployed and broke, and the flat that I live in does not have enough sun to move the plants to that source. Anybody got a really low-budget solution or idea? I can construct if need be. Wanting at least 200w

How to make stronger smell and flavour in DWC grows?
Hi guys. Just harvested my second ever harvest, and 2nd time with DWC. Using HPS, then CMH for last 2 weeks I'm really happy with buds, but the smell is a little less intense that I would like. I have used Cannaboost, which is supposed to increase flavour but I want more! :)

Light came on for about 30 seconds about 3 hours into the dark cycle
So Im 3 days into 12/12 and I bumped my timer last night and my light came on suddenly during the dark cycle. I immediately shut it right back off. Was I wrong in shutting it back off right away? Should I be worried about anything?

Side lights ?
Would my plants benefit from these extra lights hanged to the side? Photos included of light and how they look. Above are two SF1000D lights. Curious if these will help the under growth or if it's just a waste? Thanks for any info anyone can share . Happy growing!

will seedlings survive with just natural light?
At the moment I dont have a growing light and all the babies get is sunlight (about 15hours). Will this be enough? They are sitting at the window with a humidifier to keep them moistyyy.
