I dream of a tasty tangerine

Not getting off to the best start in terms of conditions. The heatwave is keeping temps far too high and the humidity too low, So how this grow goes we shall see. I now have air-domes in the bottom of the pots to aid better oxygen to the roots. Plus I swapped out the 600w led for a 1200w led. Again just a cheap generic ‘eBay special’ till I throw some money at a decently setup.
