After a few grows using HPS lighting and a top feed system I decided to switch to DWC and LED lighting. I have a 1mx1mx2m tent, cannafan, 100lt resevoir with 4 spaces for plants, 20 litre bucket with 1 space for plant. I'm using Viparspectra 400w LED switchable lights. Nutrients for this grow are courtesy of the good people over at Professor's Nutrients. The strain I'm growing this time around is an indica from Southern Star Seeds called Chung Lee (LA confidential x Afgooey). Started the seeds with paper towel method and after 2 days they popped and placed in wool cubes. Seedlings showing first root so placed cubes in clay pebbles in 23cm pots. Lights are switched to veg mode.

This is my first DWC so I will be asking a lot of questions about this technique. What is the best setting for the air pump? should it be on a low rate or is full blast better?

Welcome to team DWC MrMuchies! Firstly your air-pump setting can be low/medium. It really comes down to having a good air-stone! Maximum bubbles for maximum Surface-area/oxygenation! Second - I noticed your PH is at 6.3. DWC plants want 5.8PH typically (more specifically a range of 5.6 to 6 PH)

How important is air temperature to the first stages of vegetative growth? With LED lights my air temp is lower and I wonder if the lower heat is affecting the early rate if growth?

Ok , Plants have a " Wellnesstemperature" its between 22-27 Degree. Under 20 Degree/Celsius the Growth slows down. Over 28 Degree the Plant is stressed and slows down too ( and more) Your Goal is to his the Space between to have an Optimal Grow. But it not only the Temperature. Temperature and Humidity goes Hand in Hand. they depend in each other. Its called Vapor Pressure Deficit (VPD) there is anice Chart where you can look wich Temperature and Humidity you need in each Stage of your Grow. I will post it in the Comments

How early into my flowering cycle should I add a sugar based additive?

Hey there MrMunchies If you do wish to utilize a booster of this sort I highly recommend ensuring your roots are healthy and able to utilize the beneficial gains of added sugar! People have been known to start sugar supplementing as soon as flowering starts, but like I said I from my personal experience its best when your microbial life is on point to utilize the boost given by the added sugar! For DWC and hydroponics a simple product like "recharge" can help you achieve getting these microbes to the desired levels. Adding sugar at the start of flower with microbial life is the optimal move to make. Best of luck with your grow @MrMunchies feel free to ask any follow up questions you might have! 😎

Its the easiest way /and the Cheapest to look for Materials to isolate the Room / tent. For more dare to ask per Pm or in the comments

They develop good, 20 degree seem to be ok for them. The good thing is colder solution brings less problems

@Mrs_Larimar, Thank you for all your information. My tent is isolated but the problem is where I have to have it there is heating so in winter the temperature is low, luckily not like in the USA and Canada.

How have you been enjoying the DWC experience so far? What are the immediate differences that you notice between DWC and soil? 😎

@MrMunchies, Hope I was able to help resolve your question, feel free to ask anything else about when to add sugar to the grow 😇

@HighTV, It's still a bit early to compare this to previous grows but I am enjoying the growing experience. I was expecting this to be harder than it actually is. In the past I have only grown with soil outdoors which I find more like regular gardening and used cocos for my previous indoor grows. The most immediate difference so far for the better is it's a lot easier to move the plants and pots around whe.n I change the nutes.

you can flip the pre flower will come man, cut the brown roots if they look dead, should actually give the plants a growth spurt you'll see

@CRiSPrGrow, I once flipped before pre-flower and the plants went hermi on me, don't really want to run that risk again.

Beautiful roots. One reason I like DWC is that you can see the roots.

hey @MrMunchies , i actually add that molasses starting on the last watering of veg, adding two table spoons dissolved in a glass of warm water before adding it to the plain water days. I found that it kicks off the flowering. Then keep adding it weekly or twice weekly during the flower stretch to sort of accompany the stretch with carbs and the micro nutrients. you want to tapper it off around week 4 or 5 of flowering so that you don t get weed that's too sweet - yes there is such a thing lol. Check out my grows, i think you can see it there. hope this helps bro ! 🚀
