2x2growingstarted grow question 5y ago
What ppfd do you guys recommend for plants in veg?
I’m finding that my light can be too strong at max power even at a 24” distance.

250 PPF for seedlings
400 to 600 for veg
600 to 850/900 in flower.

Put your hand under the light at the height of your canopy., if your hand feels comfortable under the light for 1 minute then your girls will be fine. Cheers

Help with issues IDI 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.

ViparSpectra XS 1000 (x2) vs. HLG 100 RSpec (x2)Thoughts on VS XS 1000 (x2) vs. me buying HLG 100 RSpec (x2)? They'd go to either side of my HLG 225 in a tent that's 2.75' deep and 5' wide to 'fill the wings' more evenly. Thoughts on build, safety, quality & heat? HLG 100RSpec:0 / XS1000: (on sale this weekend)

Tent too hot?I added two blurple lights - I'm not sure how much they're helping growth but they are definitely making the tent hotter - about 5 degrees F. I have a fan blowing at the bottom of the tent and at top over the lights but I'm worried that it might be too hot. Should I ditch them?
