Where should I take the test sample from? The middle of the plant? I usually put the test samples in the oven for around 30 min on 160f/70c or is there a better way to fast dry test samples?

The plants were mature when I flipped to 12/12 as they had preflowers for at least 2 weeks. It took around 10 days to clearly show they are flowering after the switch. They should really specify when is the "8 week strain" actually ready. IMO counting from flipping is the only accurate way of...

Yes I started the count on flipping day but I didn't think they will be ready in 8 weeks like they said so I thought ok I give them 9 weeks but it's 9 weeks today and they still look not ready :(

I have 3 WW at day 62 flowering. I bought the seeds from Dutch Passion and the website said it should be over in 8 weeks (it's a 75% indica 25% sativa). I know it's not 100% accurate and I planned for around 9 weeks flowering and then cut but they are at 9 weeks flowering today and they...

This is a white widow almost 2 months old and 2 ft tall, these are 3 plants planted the same day. They have all been treated the exact same way but from the 3 plants 1 has a lot of these symptoms, 1 has a little and the last one almost none at all... The plants are under 12/12 for the last 9...

I raised the light to 27'' I hope that's enough to let them stretch a bit more (or would you advise to raise more?). On the light bulb it says minimal distance is 22'' so I thought to let them have all the light possible but that's why they are so small and bushy maybe (or it's just the strain)...

I'm growing feminized White Widow from Dutch Passion (http://www.dutch-passion.nl/en/cannabis-seeds/product/white-widow/) supposedly 75% indica 25% sativa. They are growing under a 600W HPS agro bulb (enriched with blue spectrum). The temp is 75f day and 66f night with average RH 60%. The...

So I did a TON of reading and I'm still very confused about the PH. I'm a soil grower and my tap water is around 7,5-8 PH (liquid test). I read many articles about PH and soil and half of them is saying to adjust PH to 6,5 before watering and half is saying not to bother with PH and just...

Most people in the forums and the guy in the hydro store told me that those universal (veg/flower) lamps are "ok" for both but wont excel in either and that using specific pure hps and MH would be better.... and btw the light from grolux sylvania looks just like a normal hps lamp, you cant see...

Tomorrow I will order a MH and HPS bulb. I can't decide which bulb to buy. I already bought a sylvania grolux lamp 600W that is supposed to do vegetative and flowering but I'm not very happy with it and I want a pure vegetative and pure flowering bulb. My ballast is 600W. Can anyone give...
