Jdillayoyostarted grow question 4y ago
Have lux meter for my phone didn't think to try to convert lux to par. my phones sensor only read up to 3750 lux so I borrowed a friend and checked. I'm getting around 7000 lux at canopy level with the lamps at 50 inches so all good for now :). @BraveheartGenetics cheers mate!

No problem buddy. You want about 15000 - 20000 LuX for seedlings. Converts to about 200 - 250 PAR. Happy to help, good luck and happy growing

If you use white light then watch that video. You can buy a cheap lux meter from Amazon and he converts it to PAR for you. I find this really accurate . The lux on the phone can be inaccurate unless you calibrate it with a trusted lux meter.

I Made a Big MistakeI forgot the timer open and the plant has been lighting for 2 days now. Normally I have to turn the lights off at 6 pm. What should I do?
Should I wait until 6pm? Or should I turn it off and switch to a new light schedule?

When will the plant be good?..Hi! I am a beginner grower. I converted a refrigerator for micro-growing. How long until my first plant is finished? It grew semi-open air. The box was ready a few weeks ago and I put it in. My lamp is viperspectra p600. I welcome any useful advice. Thanks.

Shifting outdoor plants from outdoor to indoorSo I was wondering if outdoor plants(week 2) getting regular sunlight (~12-13 hours) can be shifted indoors for faster growing (18/6 or 24/0 or 20/4)?
Anyone tried before? it is safe? Will it cause to make them hermaphrodite?Week 1

Light scheduleSo I got a new timer and messed up schedule. Plants got 16 hrs of light, turned lights out as soon as I noticed (5am).
11am-11pm light.(5 weeks into flower)
Should I let plants have 12hrs dark now and resume 12-12 , or let lights come on at 11am(6hrs dark)

How to tell if light is damaging plant?I'm using a Mars Hydro Ts600. Manufacturers advice is to keep height at 12'' minimum above the canopy in flower but other growers report it can hang as low as 10''. In identifying optimum height how would I be able to tell if it was too low for my plants? What should Iook for?Week 8

Additional lighting in flower???I’m planning on putting another 2 x 600wLED (blurpul colour type) alongside my current 2 x1000w led Cree cob lights. I have them spare and was hoping this will help with flower/thc production??? Is it worth putting them in or just wasting electricity. Any help appreciated 🤙✌️🎄Week 21

Nutrient burn, Light burn, or Phos Def? red stems purple bruises,Noticed red lines leaking red into the leaves with purple bruising, and the starter bottom leaves seem to be turning yellow, with the leaves above looking dark green with spots. Is this signs of light burn or nutrient toxicity? And is it lacking phosphorus or just the strain gen?
