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

Lighting cycle for VEG stage. Is 24x7 OK?
Hi, Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED Thanks, Mr.STM

Light strips
Opinions on led strips down the poles of my tent for extra light or saving up for an upgrade.... I've been talking to a fellow grower and I know I need more light in order to have a better yield. I thought 4 light strips would give light from each side plus on top. Whatcha think?

Bad idea?
Will a mars hydro TS1000 be too strong for a 60x60x140cm tent? I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.

Help with issues ID
I have a photoperiod in a 5 gal using BAS light. It is currently day 3 of week 4 , and I'm getting some damage on the tops. Would this be light stress or another issue? The tips are starting to go light green. Using the 200 watt light for the 2x4x8 ac infinity tent.
