General Cultivation Q&A

Hi dudes and dudettes, Ive finally got a bagseed growing away in my new grow cabinet. Until recently I was concerned about the possibility of high humidity in my grow cabinet but with the oscillating fan keeping everything moving and the exhaust fan working nicely, my hygrometer always say 20% now which i take to be its lowest level of display of humidity. So I thought I would ask, does low humidity pose any potential problems? cheers Morphine

hey guyz, whats some good brands of fertilizers i can buy from bunnings/nursury or whatever. And also when would be the best time to use them, like veg stage, budding etc Also i herd that when it comes to fertilizing marijuana plants, it always has to be done to 1/4 of the strength it recommends on the packet....is this true? thanks for your time btw im from SA

Hey guys I have 5 seedlings down in rockwool and 2 are showing yellow leaves. They are about 10 days old. On one of them 2 of the 4 leaves are entirely yellow and on the other just the tip is yellow. I have been spraying them with rhyzosomethingarather from canna at half strength 0.5ml /250ml. My temperatures range from 22 to 32. They are still in a propagation trays with the lid on them as well to keep up the humidity (Around 85%). When is a good time to get them out of their humid home and into the space? Humidity in the space is around 50 - 70%

Gidday fellows Stoners, I have trouble finding information on Hydroponic Run to waste setup. I plan on doing a stealth grow in a working 370 Litre fridge. My biggest problem is I need to leave the setup on its own for 2 weeks at a time. Originally I wanted to setup a DWC recirc system with water chiller. However after reading more and more on the subject and from previous experience I believe the uneven uptake of Nutes verses water will cause big PH issues that I can't attend to and ultimately Nute deficiency's. I believe my only safe option is to use a Run to waste system. Here are my thoughts. I would like feedback thanks. I thought of running 2 pots 250mm…

Been reading about auto flowering strains like AK47, Lowrider etc. Pretty fascinated with the concept of discreet plants you can place anywhere & harvest up to three times an ouotdoor growing season. Any feedback on strains, reliable seed companies & techniques would be appreciated. Cheers

I have a few of these fertilisers in their raw chemical form which i mix with water in highly concentrated amounts to dose aquatic plants. does anyone think these would benifit seedlings or would they cause harm? eg burning. Potassium Sulphate K2SO4 Monopotassium Phosphate KH2PO4 Magnesium Sulphate MgSO4 Potassium Nitrate KNO3 Assorted trace elements in powder form. cheers Merc.

has anyone else heard this saying? How accurate is it? Merc.

Hi, my lights accidentally were too close to my 3 day old seedlings for an evening and they are dry and flopped over but half of the stem is still strong. Should I start again or can the seedlings be saved somehow?

I need some help...... Ive been reading about teas with guano, kelp, earthworm castings & molasses. I found a recipe that looks like this - does this sound good? VEG TEA PER GALLON WATER 2 TBSP Peruvian Seabird Guano – 10 – 10 - 2 2 TBSP Mexican Bat Guano - 10 – 2 - 1 or (blood meal 13-0-0??) 2 TBSP Kelp Extract - 0 - 0 - 2 2 TBSP Earthworm Castings - 1 - 0.5- 0.5 2 TBSP Blackstrap Molasses - 2 - 0 – 10 TOTAL NPK - 23 - 12.5 - 15.5 For a flowering mix, the Mexican Bat Guano (high N) would be replaced with Indonesian Bat Guano (high P) I have a airpump to aerate a 4 litre bucket. How bad is …
