White Widow – 180gram harvest from one plant by Mr Rhino.


White Widowis consistently one of the best selling and most praised Dutch Passion varieties.  It is a variety with a reputation for producing exceptionally strong marijuana, and it does so in generous quantities.  In this weeks blog we detail a special grow which gave a very tasty 180 gram harvest (6.5 ounces) for a Dutch Passion customer called Mr Rhino who grew a single White Widow under a 600W HPS light and got a spectacular result.

For anyone who is unsure which variety to try growing next, White Widow is a safe choice.  The ‘White Widow’ name comes from the ‘white’ crystalline appearance of mature females due to the heavy levels of resin production which covers both the buds and fan leaves.  White Widow was created many years ago by a Dutch grower named Ingemar.  Dutch Passion brought original seeds of this carefully selected variety to the market many years ago and it has won countless awards over the years.

The Dutch Passion team were really impressed with this White Widow grow from ‘Mr Rhino’ and we thought our readers would be interested to see just how well White Widow can perform.  The original grow diary is here on the popular UK420 forum
It began when Mr Rhino germinated 5 feminized Dutch Passion White Widow seeds.  He grew them all and selected the best single specimen to take through to maturity.  This plant was grown vegetatively for 8 weeks under conditions of around 18-24 hours of daily light.  During this period the plant grows roots, branches and leaves but no bud.  Plants given a long time in ‘veg’ often have the foundation to become very productive when they are flowered.  She was grown in a 15 litre container with Plagron Batmix soil.  This is a quality soil enriched with bat guano.  Today many growers buy ready-mixed compost from specialist manufacturers and get great results whether they are new growers or veteran growers.

Daily light was reduced to 12 hours after 8 weeks –and  flowering began.  The White Widow had been skilfully trained underneath a netting.    This technique involves keeping the growing tips of the white widow underneath the netting.  Only the flowering heads are allowed to grow vertically.  Although the photo’s look like there are several plants growing in fact it is only a single White Widow with around 20 well sized cola’s.   The benefit of this method is the efficiency; the 600W HPS is able to get strong intense light on all the blooms.  The result is very heavy harvests. 
The White Widow was fed with 2ml/litre Plant Magic Oldtimer bloom nutrient in the early part of flowering.  By day 27 she was feeding on 3.5ml/litre.  By Day 40 she was on 4ml/litre.  Eventually she reached 5ml/litre of feed.  Like all good growers Mr Rhino was able to steadily increase the nutrient concentrations without over-feeding and ‘burning’ the leaves and roots.  The result was the spectacular growth seen here.  Mr Rhino commented that White Widow gave “very vigorous growth both in veg and flower.  White Widow was good to ‘top’ (end up with lots of colas!).  A very forgiving plant, you can throw what food you like at her and she will be happy.”

You can see numerous well sized blooms, it is rare to see a grow performed as expertly as this.  Mr Rhino had removed the growing tip of the plant (‘topping’) to encourage the plant to produce all the blooms you see here. White Widow is a resin-rich variety so the buds are heavy and grind up really easily with all the oil within. On the photo’s you can see the resin is oozing from the leaves as well.  The final yield was 180 grams.  Mr Rhino was wise enough to keep a cutting from this great White Widow; he can grow it in the future knowing that he has massive growth potential. 

In warmer climates such as Spain, White Widow can be grown successfully outdoors and when rooted into quality soil will turn into a well sized bush that can yield heavily.  Mr Rhino harvested his White Widow after 9 weeks of flowering.  As you can see from the bud photo’s he got some top quality pot for his efforts.  Each of the blooms was soaked with resin and the photo’s show just how well formed and dense the buds were.

All in all this was a great result from Mr Rhino and his reward is a 180g supply of top quality weed.  Dutch Passion congratulate Mr Rhino on a superb grow!  We give the final words to Mr Rhino himself who made the following conclusion “White Widow smells nice of lemon/pine, not too overpowering so may appeal to those that need a low odour strain.  My best point with this plant was the strength, potent! Buzz starts around the eyes and slowly works its way down the body, not very couchlocky either.  All in all a good strain and I'm happy!!”

1 plant per light is a great way to grow i have done many grows under a 600 always netting and removing all lower small bud growth under the canopy right up until week 3 of flowering. i feel this is the best way to grow.minimum plants maximum harvest .i always reap around 18 to 23 oz dry weight 23 being the highest. the more plants you pack in the less you will recive per plant.my nost recent grow was 4 under 2x600watt hps yeildind 51oz at dry weight. i tip i would give is when growing scrog style like this fresh air good air circulation temps and hymidity are key i found that when i started goimg for bumpa max harvests you can attract mould .i always inspect daily and make sure the hymidity is just right. anyhow try it people and with some practice youll be amazed at what one of these fine plants can yeild.

Defo males, at week 4 of flower the buds should be the size of marbles ,, been growing this strain for a few years now after taking cuttings off cuttings about 13 times and still going strong with no signs of weak plants after so long,, very strong consistent plant even when grown in tent over the summer with temps reaching 47 still produced around 3.5 oz per plant if grown in coco they thrive in a ph of 5.5 early on then raising to to 5.8 at last 3 weeks

hi..! The PH is not the same for the coco ( = +/- 5,7) & the soil ( +/- =6,4) .. You must have a ph meter , that' s best way to do coco , and for the soil you can use PH 's paper for testing your water .. that' s minimum if you want make the good job..

Mark, watering frequency is almost impossible to advise on. It depends on the size of the plant, the size of the container, the size of light, ambient temperatures etc. What we can say is that over-watering and over-feeding are two of the most common errors by new growers. One good tip is to get a feel for how much the plant pot weighs, and water her only when you think she needs it. Thats better than over-watering

I always leave my plants in total darkness for 24-48 hours before harvest I find it gives them time to wind down and they get realy sticky, the best way to check the ph in ur soil is to get a digital ph pen and and cf stick and a small 50ml medicine cup once fed with what ever yiur watering with lift the pot up and let all the water drain out of the bottom of the pot and it's the last few drips you want to be collecting to get a accurate reading off what's going on in ur soil this is the best time to check the cf as well if it's high on the stick ie above 24 and over let the pot dry and feed it pure phd water and have a nice bit of runoff check cf and will bring it down to a comfortable level to were the plant will absorb all nutrients, if growing in the summer I'd recommend this every other feed if watering by hand reason being is in extreme heat ie over 35 which is inevitable in a tent in summer the plant drinks the water quicker and leaves all the nutrients still in the coco so to avoid a lock out always use water every other feed, coco ph,,, plants thrive 5.5 early on veg up to 5.9 in flower any thing over and plants start to look ruff, soil is any thing from ph 6 up to 7, yiur plants will tell you if the ph is right if it's spot on they will be reaching for the Lazers like there on md,, if ph is off the will look like there a massive come down ie leaves drooping yellowing not growing, get your ph right and you have cracked it, %99 of all probs are ph related people just don't realise this so coco 5.5-early 5.9 late flower

Ruby, 27th April. You will need a decent climate (central/southern Europe) to grow White Widow outside. You can plant seeds after the last frost, she should be ready to harvest in October. If your climate is more Northern European then consider an outdoor variety such as Frisian Dew, Frisian Duck or Durban Poison. Germinate indoors, and good luck!

Is it best to ph water and let it sit for a day then add nutes or add nutes them ph. I've been trying to look up information but have yet to see anything. I am planning to start a new grow soon just want to be on top of things. Also is it better to switch to LED lights my hps lights cause a lot of heat and that's why I think I get airy buds

Jay, 8th Sept 2017. Most people add their nutrients to the water and check pH of the FINAL nutrient solution. LED is a popular new light choice, they are more expensive than HPS but technically they do a great job with reduced heat and better spectrum.

Marks Widow, 9th July 2018. Sounds like a good grow, and you are guaranteed some top drawer smoke with this variety. I would be tempted to start flushing after 8 or 9 weeks of bloom, depending on how you like the high. And give her a week of flushing. It's a magnificent smoke after an extra week of bloom, heavy and satisfying.
