One small plant for one new grower

A question from a fellow grower:

I feel like my temperatur is too low and my light as well, what do you guys think about it, what needs to change about my setup? I started changing to a flower phase light cycle today.
Strain; Type, Bag seed, or NA: Dela Haze, got it as a cuttling
Soil in pots, Hydroponic, or Coco?: Coco
System type?: It is in a room, that I tried to make a little smaller by putting sheets up (I do not have a growing tent yet)
PH of runoff or solution in reservoir?: none
What is strength of nutrient mix? 4ml per litre of water (Plagron Alga Bloom) will start tomorrow with that.
Indoor or Outdoor, Indoor
Light system, size? Halogen Lamp 190W (E27)
Temps; Day, Night: 23celsius, 20celsius. I would like to know how I can keep it warmer at nights, considering the fact that I don’t have a tent.
Humidity; I do not really know, around 50% I am guessing
Ventilation system; none atm
Co2; Just from the fresh air that I let get into the room from time to time


Hey there claire i was just reading a thread of yours from back in '14 about ppm and ph it was interesting, did you get it sorted, i too am trying to get a grip on ph and ppm or ec at the moment but a lot of it seems to be in hydro and im growing in soil and outside, so im just searching the forum and reading everything. The other guys will read this soon im sure and let you know whats what, sorry i cant help you more. Hope it gets sorted soon @latewood @Donaldj @ktreez420

Halogen is not the right type light, perhaps @Niala an explain why ?

@deb1 hello I wanted to mention that Claire is a worker for ilgm, the Posts she puts up are from Growers who wish to stay Anonymous, she’s not a grower, per se, hope this helps …best wishes!


ok thankyou @Paranorman didnt realise they were from growers

As you can see in these graph, halogen have a lack of the blue spectrum, they are a more in the “warm” side, it can be a good choice for flowering, however, the main problem with halogen lamp is the energy effeciencie and the heat they produce, in this specific case, it seems not to be a heat problem, but if the plant show sign of stretching, that’s most probably due to the lack of blue spectrum and in that case the light should be put more closer from the canopy and that can be a problem. It can lead to heat stress and light burn.

The temperature is nearly perfect, so, their is no worry to have about it :wink: :innocent:

Hoping that’s helping you, fellow grower :grinning:

(Thanks for the tag @Paranorman)

Edit : The Plagron Alga Bloom as this in it; Composition: Water, beet vinasse, amino acids and algae extracts. Organic NPK-fertilizer (3-2-5). Total nitrogen 3.3% (N), of which 3.3% organically bounded nitrogen, 2,3% water-soluble phosphorus pentoxide (P2O5) and 5.4% water-soluble potassium oxide (K2O).

It’s too weak on PK, you should invest in a jamaican bat guano like this one to give more phosphore

Or this

Or this

You should consider to invest in a LED light like this one

Or this one

I hope that’s gone a help you, fellow grower :grinning:

Exactly right. Claire works ffice and transfers emails from un registered growers. Then we answer them…Well…errr…LOL This one :slight_smile: the oi


Hey there! This question was actually sent from me, but I deleted the E-Mail by accident.(Getting to know more about the forum, I now post directly to it^^)
Anyhow, you seem to know quite a lot about the stuff that interests me, so I might aswell ask you another few questions if you don’t mind :slight_smile:
What means “Organic NPK-fertilizer (3-2-5)” I am especially curious about the numbers^^
I now have a new lamp made for plants, it’s called “Erligpowht Plantlamp 45 Watt 225 LEDs Red&Blue LED-Plantlamp”, what do you think about it, can I flower with it? (I translated it’s name from the german original)
I’ve put my plant into another room, where it has 24,7/20,5 Celsius Day/Night at average.
Hope to hear from you soon, Deibiddo :slight_smile:

The NPK mean Nitrogen Phosphorus Potassium and the number mean the % of each in the nutrients mix. Those are essential for plants to grow, here’s how they work : Nitrogen (N): leaf growth; Phosphorus (P): Development of roots, flowers, seeds, fruit; Potassium (K): Strong stem growth, movement of water in plants, promotion of flowering and fruiting;

So, cannabis plant, espacelly in flowering stage, is high demanding in Phosphorus and Potassium and you should and must take this in consideration. The % of PK as to be at least between 10 and 20 (each, ex: P20, K15 to avoĂŻd PK deficiency) and a medium-low N (to avoĂŻd N toxicity) for the plant to produce a decent yielding and potency.

The Plagron Alga Bloom as NPK of 3-2-5 and it’s too weak in PK, so, that’s why I have suggest you to boost them :relaxed:, and since you’re growing in coco, you have to give your plant enough nutrients because coco do not have NPK in it.

For your lamp, it’s simply not powerful enough, invest in a 300W LED light, minimum, like this one (the best for your money)

Light is as important as nutrients, more light penetration, more photosynthesis , more yielding, more potency.

If you can’t invest, do not expect your DelaHaze to thrive as it should be and give you a honnest yielding and potency with a lamp like the one you have. You can keep it for the last 3 to 4 days before harvesting (for the last ripening) or for less light demanding plant such as herbs, salads, comestible flowers…

Hoping that’s helping you @Deibiddo

P.s. growing in coco pH should be between 5.8 and 6.1 depend on how your cannabis plant response.


Thank you so much! I will consider buying a better lamp (maybe add the 190W Halogen to my LED for now?). One more question came to my mind, my plant was in flowering for 2 weeks now with this light that I told you about. Should I add those weeks to the flowering phase?
