1st Coco Grow - Critical + 2.0

[MJ1771]

Hello guys, so yet another "1st whatever" thread but I'm really out of names right now so we'll stick with the default layouts.

So, a bit information about the grow,

The strain is Critical + 2.0

300x150 tent with 5x600 lights that will have 16 plants in it
100x100 tent with 1x1000w light that will have 4 plants in it

32 seeds were popped on 25/12/2017.

Currently I have 28 seedlings in 1.2 litres which will be transplanted as soon as they are ready to.

I will make my best updating the journal daily, any help and advices would be really appreciated as this is my first coco grow, have been a soil grower only so far.
Will appreciate any questions and critics so please dont mind :d

Its our second day on 18/6, just watered the pots to run off with around 100 ml water and slight feed.

Today's feed was (RO Water)
CalMag to 0.19 PPM
PH Perfect to 0.44 PPM
0.3ml/litre Roots Excel
2 ml/litre Voodoo Juice

Hello! That's a pile of plants! I think you want to get your humidity up closer to 60% for your seedlings. Also, how close are your lights? Can't tell if they are stretching. Otherwise, looks good! I'm subbed up for the ride! .

 

[MJ1771]

Its a 400w bulb that is exactly 45 cm away (Distance from bulb to leaf), the humidity is around 60ish, but I have forgot the dehumidifier on wrong option (I'm in a sealed room so always have to use it) and when I went @ the grow the humidity was ultra low, lol.

 

[MJ1771]

Today's feed was (RO Water)
CalMag to 0.19 PPM
PH Perfect to 0.50 PPM
0.3ml/litre Roots Excel
2 ml/litre Voodoo Juice
1 drop of SuperVit

Gave dem girlz a bit less water, around 60 ml cause they were making 2 big run off @ 100 ml's.

Yeah the girls are looking great! This isn't your first time growing is it?

 

[Killerbudz]

Coco is an awesome medium easy to grow in. Have you thought out setting up a drip system of some sorts? Feeding that many plants while flowering might get tiresome.

I have only growed once in soil so far and this is my first coco grow, second overall.

Yeah, I have thought about this but I want to do it hand feed this cycle so I get to know the coco and its needs better. I believe the only way to achieve this is have daily look @ the plants and this is not a problem for me.

I have been following How to Grow in Coco by Cultivator. If you are growing using Coco I believe it might be useful for you.

Coco is a great medium! I've only had one grow but it has been great to this point. However, because you do need to water every day it can get to be a lot of work watering them. I have to take mine out of my tent to water and that made me decide to put a drip system in place for my next grow.

 

[MJ1771]

I'm not afraid from work and hassle and I have the time to, but you guys definitely gave me a thought.
I'll look @ the drip feed systems just to save the time watering each pot alone...

 

[Killerbudz]

I'm scared to think about how much water 28 plants will require down the final stretch lol. My one plant could take 1/2 gal like a champ.

 

[MJ1771]

Out of these 28, I will select 20 and put them in two tents

 

[MJ1771]

Today's feed was (RO Water)
CalMag to 0.21 PPM
PH Perfect to 0.51 PPM
0.3ml/litre Roots Excel
2 ml/litre Voodoo Juice
1 drop of SuperVit

60 ml of water, totalz.

I have 5 and its a lot lol good call

Right, especially when your feeding 2 or 3 times a day when flowering.

Yeah it's nuts I'm feeding twice a day right now in preflower ppm in though only 500-600 trying to get her going slowly weening her off the nitro and say eat. Lol and more nitro we out the more higher chance at pest as it attracts pest ?

I'm not sure about that. Think pest have more to do with the environment than nutrients, but I'm no expert.

 

[MJ1771]

What kind of drip are you using guys?

+1 Killerbudz I think the environment, especially light intensity and humidity is way more important than the nutes.
HOWEVER, I believe the organic nitrogen nutes such as BioBizz Grow or Fish Mix can attract more pests especially if used in coco conditions such as watering daily and a few times.

I personally had HUGE infestation when I started foliar spraying my first attempt to make mother plants with Nitrozyme and Fish Mix but I have to admit that I overdosed on using them, soo....

The solution to any kind of pest for me is a sulfur burner, im the kind of guy who panics out quickly and wants results quickly aswell, even killed my previous grow on neem oil overdose, lol.
I can't swear by it cause I haven't had any pest problems so far, but I have researched very deeply regarding this subject and this is a very nice and easy solution for such a big problem. The main thing it does is - prevention if you have no bugs/pests or if you have you can just burn more and more per night so when they are done - you just keep doing it once for a week and it'll be good. Thing is its 100 bucks so...

The only potential issue with the sulphuric burner is if you do it too close to harvest and your buds end up with that horrible taste they sometimes can get. Similar to burnt rubber.

Ye, totally forgot that. Even on the manual they say not to use it 3 weeks from harvest cause it can damage it. For prevention you can use it 1 or 2 times weekly and it'll be all good unless your room is totally out of control lol.
Thanks you for mentioning, important one.
