Choosing a cannabis strain for an indoor grow can be a time-consuming process. However, the White Widow cannabis from ILGM is a great strain to grow indoors. It’s an even greater strain to grow in a Deep Water Culture (DWC) system.
DWC is a form of hydroponics wherein marijuana plants are grown aerated in water. It is considered the purest form of hydroponics. A DWC system is easy to put together. All you need is a container, lid, pump, and a net pot!
This grow journal records a cannabis grower’s efforts in cultivating White Widow cannabis from ILGM in a DWC setup.

April 13th
Dropped a White Widow autoflower seed directly into rapid rooter soaked in pH 5.8 water and covered it up. After a couple of days, she had a tap root coming out of the bottom but it hasn’t broken through the surface yet.
April 14th
She popped overnight and has a really good looking inch of root coming out the bottom.
She goes into her new home – a 5-gallon DWC system. Have the water just barely touching the net pot filled with hydroton. Will place the rooter in the center and fill in with the rest of the hydroton.
You can see in the first two photos the setup includes simple 3mm hooks. They are small enough to sun a small twine or twisty tie through them for some later training.

She’s looking even better. Now she’s standing tall on her own!
She’s under a dome to receive more heat than the tent and lights can provide on their own.
However, ice packs and frozen water bottles are on hand to cool her down if necessary.
April 20th
It’s her 7th day and she’s still looking good.
April 23rd
Day 10. Not much to report other than this plant working hard on her second set of leaves.
April 28th
Day 15 and her new sets of real leaves have arrived. Check her out!
May 4th
Day 21. Not much to report. She got a reservoir water change along with a low dose of nutrients. The pH is 5.87 and PPM is 240. The leaves are starting to yellow and that means she’s using up the food provided by those leaves.
May 9th
The first few pistils have started showing this morning!
Going to change her reservoir water today. Using Fox Farms Trio. Cut down the feedings in half and added a little Tiger Bloom since she is beginning to flower. This is a slight modification on the Fox Farm hydroponic feeding schedule. Instead of 3 teaspoons per gallon, she will receive half a dose of Grow Big and half a dose of Tiger Bloom.
After 5 minutes, the PPM was 545 and the pH was 5.86.
After a few more minutes, the pH and PPM settled down to 5.82 and 550.
May 10th
The leaves are still yellowing slightly but all signs point to her bright future and full recovery.
May 12th
On her 29th day, she’s moving along just right. Yellowing has decreased a lot and the pistils are developing well enough.
May 16th
She got another reservoir change today along with some Liquid Karma, Tiger Bloom, and Big Bloom. Also added another air pump to the bucket. Let’s see if she does well!
May 17th
34th day from seed and she has already produced close to twice the amount of leaves since the last photo update. Her vertical growth isn
